Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates
|
||||
the terms and conditions of version 3 of the GNU General Public
|
||||
License, supplemented by the additional permissions listed below.
|
||||
|
||||
0. Additional Definitions.
|
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser
|
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
||||
General Public License.
|
||||
|
||||
"The Library" refers to a covered work governed by this License,
|
||||
other than an Application or a Combined Work as defined below.
|
||||
|
||||
An "Application" is any work that makes use of an interface provided
|
||||
by the Library, but which is not otherwise based on the Library.
|
||||
Defining a subclass of a class defined by the Library is deemed a mode
|
||||
of using an interface provided by the Library.
|
||||
|
||||
A "Combined Work" is a work produced by combining or linking an
|
||||
Application with the Library. The particular version of the Library
|
||||
with which the Combined Work was made is also called the "Linked
|
||||
Version".
|
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the
|
||||
Corresponding Source for the Combined Work, excluding any source code
|
||||
for portions of the Combined Work that, considered in isolation, are
|
||||
based on the Application, and not on the Linked Version.
|
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the
|
||||
object code and/or source code for the Application, including any data
|
||||
and utility programs needed for reproducing the Combined Work from the
|
||||
Application, but excluding the System Libraries of the Combined Work.
|
||||
|
||||
1. Exception to Section 3 of the GNU GPL.
|
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License
|
||||
without being bound by section 3 of the GNU GPL.
|
||||
|
||||
2. Conveying Modified Versions.
|
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a
|
||||
facility refers to a function or data to be supplied by an Application
|
||||
that uses the facility (other than as an argument passed when the
|
||||
facility is invoked), then you may convey a copy of the modified
|
||||
version:
|
||||
|
||||
a) under this License, provided that you make a good faith effort to
|
||||
ensure that, in the event an Application does not supply the
|
||||
function or data, the facility still operates, and performs
|
||||
whatever part of its purpose remains meaningful, or
|
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of
|
||||
this License applicable to that copy.
|
||||
|
||||
3. Object Code Incorporating Material from Library Header Files.
|
||||
|
||||
The object code form of an Application may incorporate material from
|
||||
a header file that is part of the Library. You may convey such object
|
||||
code under terms of your choice, provided that, if the incorporated
|
||||
material is not limited to numerical parameters, data structure
|
||||
layouts and accessors, or small macros, inline functions and templates
|
||||
(ten or fewer lines in length), you do both of the following:
|
||||
|
||||
a) Give prominent notice with each copy of the object code that the
|
||||
Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
4. Combined Works.
|
||||
|
||||
You may convey a Combined Work under terms of your choice that,
|
||||
taken together, effectively do not restrict modification of the
|
||||
portions of the Library contained in the Combined Work and reverse
|
||||
engineering for debugging such modifications, if you also do each of
|
||||
the following:
|
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that
|
||||
the Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
c) For a Combined Work that displays copyright notices during
|
||||
execution, include the copyright notice for the Library among
|
||||
these notices, as well as a reference directing the user to the
|
||||
copies of the GNU GPL and this license document.
|
||||
|
||||
d) Do one of the following:
|
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this
|
||||
License, and the Corresponding Application Code in a form
|
||||
suitable for, and under terms that permit, the user to
|
||||
recombine or relink the Application with a modified version of
|
||||
the Linked Version to produce a modified Combined Work, in the
|
||||
manner specified by section 6 of the GNU GPL for conveying
|
||||
Corresponding Source.
|
||||
|
||||
1) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (a) uses at run time
|
||||
a copy of the Library already present on the user's computer
|
||||
system, and (b) will operate properly with a modified version
|
||||
of the Library that is interface-compatible with the Linked
|
||||
Version.
|
||||
|
||||
e) Provide Installation Information, but only if you would otherwise
|
||||
be required to provide such information under section 6 of the
|
||||
GNU GPL, and only to the extent that such information is
|
||||
necessary to install and execute a modified version of the
|
||||
Combined Work produced by recombining or relinking the
|
||||
Application with a modified version of the Linked Version. (If
|
||||
you use option 4d0, the Installation Information must accompany
|
||||
the Minimal Corresponding Source and Corresponding Application
|
||||
Code. If you use option 4d1, you must provide the Installation
|
||||
Information in the manner specified by section 6 of the GNU GPL
|
||||
for conveying Corresponding Source.)
|
||||
|
||||
5. Combined Libraries.
|
||||
|
||||
You may place library facilities that are a work based on the
|
||||
Library side by side in a single library together with other library
|
||||
facilities that are not Applications and are not covered by this
|
||||
License, and convey such a combined library under terms of your
|
||||
choice, if you do both of the following:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work based
|
||||
on the Library, uncombined with any other library facilities,
|
||||
conveyed under the terms of this License.
|
||||
|
||||
b) Give prominent notice with the combined library that part of it
|
||||
is a work based on the Library, and explaining where to find the
|
||||
accompanying uncombined form of the same work.
|
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU Lesser General Public License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Library as you received it specifies that a certain numbered version
|
||||
of the GNU Lesser General Public License "or any later version"
|
||||
applies to it, you have the option of following the terms and
|
||||
conditions either of that published version or of any later version
|
||||
published by the Free Software Foundation. If the Library as you
|
||||
received it does not specify a version number of the GNU Lesser
|
||||
General Public License, you may choose any version of the GNU Lesser
|
||||
General Public License ever published by the Free Software Foundation.
|
||||
|
||||
If the Library as you received it specifies that a proxy can decide
|
||||
whether future versions of the GNU Lesser General Public License shall
|
||||
apply, that proxy's public statement of acceptance of any version is
|
||||
permanent authorization for you to choose that version for the
|
||||
Library.

that, you must configure your build using cmake.
|

mkdir kmess2-build
|

Then configure your build using cmake,
|

and point to the source folder:

If the cmake scripts did not display any errors, you can run:
|
||||
To ease the building process, KMess comes with a 'configure' script that
|
||||
creates the directory and runs CMake for you. To build this package, simply
|
||||
run:
|
||||
|

cd kmess
|

./configure
|

make

To install on most systems, you can run:
|
||||
|
||||
make install
|
||||
sudo make install
|
||||
|
||||
If your system doesn't come with sudo, you can use:
|
||||
|
||||
su -c 'make install'
|
||||
|
||||
That's it!
|
||||
Of course, building without the configure script is also possible:
|
||||
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|

The configure script automatically makes the right build for you. For a release (non-alpha or beta)

package, the configure script builds KMess in release mode; for an alpha or beta package, KMess will

||||
run in debug mode. When something goes wrong, debug mode will help us find the cause, and fix it. :-)

Try the following switches the change the build.

If you want to modify your build, you can try the following options to the configure script:

--prefix=/usr
|
||||
|
||||
Install in the /usr directory instead.

--build-type=(one of debug,debugfull,release,relwithdebuginfo,minsizerel)
|
||||
|
||||
Set the preferred build type, which sets recommended compiler flags automatically.
|
||||
Tell CMake to build this specific build type.
|

Also consider running "ccmake" for an curses-interface to cmake.
|

Important:
|
||||
==========
|
||||
|
||||
The configure script tries to detect your KDE3 directory automatically.
|
||||
If configure fails to detect KDE, you should tell KMess which directory
|
||||
to use. Basically, we're talking about the parent directory
|
||||
of /share/apps/k~bunch of kapps~
|
||||
|
||||
Not doing this will result in emoticons being displayed
|
||||
as text, and icons being displayed incorrectly as well.
|
||||
|
||||
If configure tells you you're missing something that you think you
|
||||
have installed on your system, you probably need to install the
|
||||
"devel" version of that thing. i.e. If it tells you you're missing
|
||||
libfam, install the libfam-devel rpm.
|
||||
|
||||
More information can be found in the README file.
|
||||
The following paragraphs below provide generic installation instructions:
|
||||
|
||||
|
||||
|
||||
Basic Installation
|
||||
==================
|
||||
|
||||
These are generic installation instructions.
|
||||
|
||||
The `configure' shell script attempts to guess correct values for
|
||||
various system-dependent variables used during compilation. It uses
|
||||
those values to create a `Makefile' in each directory of the package.
|
||||
It may also create one or more `.h' files containing system-dependent
|
||||
definitions. Finally, it creates a shell script `config.status' that
|
||||
you can run in the future to recreate the current configuration, a file
|
||||
`config.cache' that saves the results of its tests to speed up
|
||||
reconfiguring, and a file `config.log' containing compiler output
|
||||
(useful mainly for debugging `configure').
|
||||
|
||||
If you need to do unusual things to compile the package, please try
|
||||
to figure out how `configure' could check whether to do them, and mail
|
||||
diffs or instructions to the address given in the `README' so they can
|
||||
be considered for the next release. If at some point `config.cache'
|
||||
contains results you don't want to keep, you may remove or edit it.
|
||||
|
||||
The file `configure.in' is used to create `configure' by a program
|
||||
called `autoconf'. You only need `configure.in' if you want to change
|
||||
it or regenerate `configure' using a newer version of `autoconf'.
|
||||
|
||||
The simplest way to compile this package is:
|
||||
|
||||
1. `cd' to the directory containing the package's source code and type
|
||||
`./configure' to configure the package for your system. If you're
|
||||
using `csh' on an old version of System V, you might need to type
|
||||
`sh ./configure' instead to prevent `csh' from trying to execute
|
||||
`configure' itself.
|
||||
|
||||
Running `configure' takes a while. While running, it prints some
|
||||
messages telling which features it is checking for.
|
||||
|
||||
2. Type `make' to compile the package.
|
||||
|
||||
3. Type `make install' to install the programs and any data files and
|
||||
documentation.
|
||||
|
||||
4. You can remove the program binaries and object files from the
|
||||
source code directory by typing `make clean'.
|
||||
|
||||
Compilers and Options
|
||||
=====================
|
||||
|
||||
Some systems require unusual options for compilation or linking that
|
||||
the `configure' script does not know about. You can give `configure'
|
||||
initial values for variables by setting them in the environment. Using
|
||||
a Bourne-compatible shell, you can do that on the command line like
|
||||
this:
|
||||
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
|
||||
|
||||
Or on systems that have the `env' program, you can do it like this:
|
||||
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
|
||||
|
||||
Compiling For Multiple Architectures
|
||||
====================================
|
||||
|
||||
You can compile the package for more than one kind of computer at the
|
||||
same time, by placing the object files for each architecture in their
|
||||
own directory. To do this, you must use a version of `make' that
|
||||
supports the `VPATH' variable, such as GNU `make'. `cd' to the
|
||||
directory where you want the object files and executables to go and run
|
||||
the `configure' script. `configure' automatically checks for the
|
||||
source code in the directory that `configure' is in and in `..'.
|
||||
|
||||
If you have to use a `make' that does not supports the `VPATH'
|
||||
variable, you have to compile the package for one architecture at a time
|
||||
in the source code directory. After you have installed the package for
|
||||
one architecture, use `make distclean' before reconfiguring for another
|
||||
architecture.
|
||||
|
||||
Installation Names
|
||||
==================
|
||||
|
||||
By default, `make install' will install the package's files in
|
||||
`/usr/local/bin', `/usr/local/man', etc. You can specify an
|
||||
installation prefix other than `/usr/local' by giving `configure' the
|
||||
option `--prefix=PATH'.
|
||||
|
||||
You can specify separate installation prefixes for
|
||||
architecture-specific files and architecture-independent files. If you
|
||||
give `configure' the option `--exec-prefix=PATH', the package will use
|
||||
PATH as the prefix for installing programs and libraries.
|
||||
Documentation and other data files will still use the regular prefix.
|
||||
|
||||
If the package supports it, you can cause programs to be installed
|
||||
with an extra prefix or suffix on their names by giving `configure' the
|
||||
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
|
||||
|
||||
Optional Features
|
||||
=================
|
||||
|
||||
Some packages pay attention to `--enable-FEATURE' options to
|
||||
`configure', where FEATURE indicates an optional part of the package.
|
||||
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
|
||||
is something like `gnu-as' or `x' (for the X Window System). The
|
||||
`README' should mention any `--enable-' and `--with-' options that the
|
||||
package recognizes.
|
||||
|
||||
For packages that use the X Window System, `configure' can usually
|
||||
find the X include and library files automatically, but if it doesn't,
|
||||
you can use the `configure' options `--x-includes=DIR' and
|
||||
`--x-libraries=DIR' to specify their locations.
|
||||
|
||||
Specifying the System Type
|
||||
==========================
|
||||
|
||||
There may be some features `configure' can not figure out
|
||||
automatically, but needs to determine by the type of host the package
|
||||
will run on. Usually `configure' can figure that out, but if it prints
|
||||
a message saying it can not guess the host type, give it the
|
||||
`--host=TYPE' option. TYPE can either be a short name for the system
|
||||
type, such as `sun4', or a canonical name with three fields:
|
||||
CPU-COMPANY-SYSTEM
|
||||
|
||||
See the file `config.sub' for the possible values of each field. If
|
||||
`config.sub' isn't included in this package, then this package doesn't
|
||||
need to know the host type.
|
||||
|
||||
If you are building compiler tools for cross-compiling, you can also
|
||||
use the `--target=TYPE' option to select the type of system they will
|
||||
produce code for and the `--build=TYPE' option to select the type of
|
||||
system on which you are compiling the package.
|
||||
|
||||
Sharing Defaults
|
||||
================
|
||||
|
||||
If you want to set default values for `configure' scripts to share,
|
||||
you can create a site shell script called `config.site' that gives
|
||||
default values for variables like `CC', `cache_file', and `prefix'.
|
||||
`configure' looks for `PREFIX/share/config.site' if it exists, then
|
||||
`PREFIX/etc/config.site' if it exists. Or, you can set the
|
||||
`CONFIG_SITE' environment variable to the location of the site script.
|
||||
A warning: not all `configure' scripts look for a site script.
|
||||
|
||||
Operation Controls
|
||||
==================
|
||||
|
||||
`configure' recognizes the following options to control how it
|
||||
operates.
|
||||
|
||||
`--cache-file=FILE'
|
||||
Use and save the results of the tests in FILE instead of
|
||||
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
|
||||
debugging `configure'.
|
||||
|
||||
`--help'
|
||||
Print a summary of the options to `configure', and exit.
|
||||
|
||||
`--quiet'
|
||||
`--silent'
|
||||
`-q'
|
||||
Do not print messages saying which checks are being made.
|
||||
|
||||
`--srcdir=DIR'
|
||||
Look for the package's source code in directory DIR. Usually
|
||||
`configure' can determine that directory automatically.
|
||||
|
||||
`--version'
|
||||
Print the version of Autoconf used to generate the `configure'
|
||||
script, and exit.
|
||||
|
||||
`configure' also accepts some other, not widely useful, options.
|
||||
|
||||
ccmake only works after the build directory has been configured with cmake before.

Installation Tip:
|
||||
Installing KMess:
|
||||
=================
|
||||
|
||||
NOTE: This package is used to build KMess from source code.
|
||||
If you're looking for a simple way to install KMess,
|
||||
take a look at http://www.kmess.org/download/.
|
||||
|
||||
First configure your build using the configure script:
|
||||
|
||||
./configure
|
||||
|
||||
If everything went well, you can run:
|
||||
|
||||
make
|
||||
|
||||
and then, as root, type
|
||||
|
||||
make install
|
||||
|
||||
That's it!
|
||||
|
||||
|
||||
|
||||
Compiling with cmake:
|
||||
=====================
|
||||
|
||||
* * this is for experienced users only * *
|
||||
|
||||
KMess 2 is KDE 4 software, which uses 'cmake' to build the software.
|
||||
To make it a bit more familiar for you, we have created a 'configure'
|
||||
script which does all the cmake magic behind the scenes.
|
||||
|
||||
It's also possible to use 'cmake' directly.
|
||||
The build commands become a little bit different.
|
||||
|
||||
First, you need to create a separate build directory:
|
||||
|
||||
mkdir build
|
||||
|
||||
Then configure your build using cmake,
|
||||
and point to the source folder:
|
||||
|
||||
cd build
|
||||
cmake ../
|
||||
|
||||
You can provide extra parameters with the '-D' option, see below.
|
||||
If the cmake scripts did not display any errors, you can run:
|
||||
|
||||
make
|
||||
|
||||
and then, as root, type
|
||||
|
||||
make install
|
||||
|
||||
|
||||
|
||||
Useful cmake parameters:
|
||||
========================
|
||||
|
||||
Try the following switches to change the build.
|
||||
|
||||
-D CMAKE_INSTALL_PREFIX=/usr
|
||||
|
||||
Install in the /usr directory instead (default is /usr/local).
|
||||
|
||||
-D CMAKE_BUILD_TYPE=[none,debug,debugfull,release,relwithdebuginfo,minsizerel]
|
||||
|
||||
Set the preferred build type, which sets recommended compiler flags automatically.
|
||||
|
||||
-D KMESS_DEBUG_OUTPUT=[1,0]
|
||||
|
||||
Activates/deactivates KMess debugging output to console, even on release builds.
|
||||
This flag is automatically enabled when the build type is "debugfull".
|
||||
|
||||
-D KMESS_ENABLE_BINRELOC=[1,0]
|
||||
|
||||
Enable support for binary relocatable binaries. This allows the binary
|
||||
to find it's resource files whatever directory it is installed in.
|
||||
|
||||
-G "MinGW Makefiles"
|
||||
|
||||
This option is required to build KMess on Windows (still experimental).
|
||||
See http://trac.kmess.org/wiki/Compiling%20KMess%20for%20Windows for details.
|
||||
|
||||
If you find this too difficult, consider using our "./configure" script
|
||||
instead. This is a wrapper these 'cmake' arguments to make it easier,
|
||||
and more familiar, to compile software.
|
||||
|
||||
Also consider running "ccmake" for an curses-interface to cmake.
|
||||
That only works after the build directory is configured with cmake before.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
* * * * * * The parts below do not apply to KMess 2 yet! * * * * * *
|
||||
|
||||
|
||||
|
||||
Important:
|
||||
==========
|
||||
|
||||
The configure script tries to detect your KDE3 directory automatically.
|
||||
If configure fails to detect KDE, you should tell KMess which directory
|
||||
to use. Basically, we're talking about the parent directory
|
||||
of /share/apps/k~bunch of kapps~
|
||||
|
||||
Not doing this will result in emoticons being displayed
|
||||
as text, and icons being displayed incorrectly as well.
|
||||
|
||||
|
||||
|
||||
Troubleshooting
|
||||
===============
|
||||
|
||||
The following packages are required to install KMess:
|
||||
- make
|
||||
- gcc
|
||||
- gcc-c++ (if available)
|
||||
- qt
|
||||
- kdelibs
|
||||
|
||||
|
||||
If your distribution uses separate "devel" or "dev" packages,
|
||||
make sure you have these packages installed also:
|
||||
- qt-devel (or qt3-devel)
|
||||
- kdelibs-devel (or kdelibs3-devel)
|
||||
- x-devel (or xfree-devel/xorg-x11-devel)
|
||||
- libstdc++-devel
|
||||
|
||||
|
||||
Likely the dependencies of these "devel" packages will
|
||||
be installed automatically. Some worth mentioning are:
|
||||
- fontconfig-devel
|
||||
- freetype2-devel
|
||||
- libfam-devel (or fam-devel)
|
||||
- libjpeg-devel
|
||||
- libpng-devel
|
||||
- zlib-devel
|
||||
- libart_lgpl-devel
|
||||
|
||||
|
||||
If configure tells you you're missing something that you think you
|
||||
have installed on your system, you probably need to install the
|
||||
"devel" package of that thing.
|
||||
|
||||
i.e. If it tells you you're missing libfam, install the libfam-devel rpm.
|
||||
|
||||
|
||||
If you get this error:
|
||||
''configure: error: no acceptable C compiler found in $PATH''
|
||||
you need to install the packages "gcc" and "make".
|
||||
|
||||
|
||||
If you get this error:
|
||||
''Your Installation isn't able to compile simple C++ programs.''
|
||||
you need to install "libstdc++-devel" and some distributions
|
||||
also require a "gcc-c++" package for C++ support.
|
||||
|
||||
|
||||
If you get this error:
|
||||
''error: Can't find X includes. Please check your installation [...]''
|
||||
you need to install the x developer packages. Depending on your distribution,
|
||||
this can be something like "x-devel", "xfree-devel", "xorg-devel".
|
||||
|
||||
|
||||
If you get this eror:
|
||||
''checking for libz... configure: error: not found.''
|
||||
you need to install the "zlib-devel" package.
|
||||
|
||||
|
||||
If you get this error:
|
||||
''configure: WARNING: libjpeg not found. disable JPEG support.''
|
||||
you need to install the "libjpeg-devel" package.
|
||||
|
||||
|
||||
If you get this error:
|
||||
''checking for Qt... configure: error:
|
||||
Qt (>= Qt 3.1 (20021021)) (headers and libraries) not found.
|
||||
Please check your installation!''
|
||||
you need to install the "qt-devel" (or "qt3-devel") package.
|
||||
|
||||
|
||||
If you get this error:
|
||||
''checking for KDE... configure: error:
|
||||
in the prefix, you've chosen, are no KDE headers installed. This will fail.
|
||||
So, check this please and use another prefix!''
|
||||
you need to make sure "kdelibs-devel" (or "kdelibs3-devel") is installed!

Installing from SVN:
|
||||
====================
|
||||
|
||||
If there is any need to install the SVN version, read on.
|
||||
|
||||
The KMess SVN repository contains the latest changes made to KMess.
|
||||
Each new feature or bugfix will be stored into SVN by developers.
|
||||
The code in SVN will eventually become the new KMess release.
|
||||
|
||||
NOTE: The SVN version is the equivalent
|
||||
of an "alpha" or "beta" release; there also is
|
||||
a little possibility that it won't even compile!
|
||||
|
||||
To install KMess from SVN you need to have the packages "autoconf"
|
||||
and "automake" installed.
|
||||
|
||||
|
||||
To download the SVN version, run these commands:
|
||||
|
||||
svn checkout http://kmess.svn.sourceforge.net/svnroot/kmess/trunk/kmess/
|
||||
|
||||
If the download succeeds, run this command:
|
||||
|
||||
make -f Makefile.dist
|
||||
|
||||
This will generate the ./configure script and Makefile templates.
|
||||
Then you can proceed with the normal installation.
|
||||
|
||||
|
||||
Each time the SVN version is updated, you can run
|
||||
|
||||
svn update
|
||||
make -f Makefile.dist
|
||||
./configure
|
||||
make
|
||||
make install
|
||||
|
||||
and you'll have the latest KMess version installed.

|

To do:
|
||||
======
|
||||
|
||||
Unfinished new features:
|
||||
___ Invite contacts for a new chat session when the current chat is used for file transfers.
|
||||
___ Invite contacts for a new chat session when the current chat has multiple participants (display dialog to choose the contact).
|
||||
___ Lookup all "TODO" items in the code.
|
||||
|
||||
Unfinished protocol features:
|
||||
___ Integrate UPnP support with file transfer invitation code.
|
||||
___ Make sure KMess can send two files at once with the classic file transfer method (test this).
|
||||
___ Support a SLP Decline/error message for a sent P2P/SLP transfer invitation, and continue to transfer over the switchboard.
|
||||
___ Support a second invitation for file transfers, detect when remote client only returns it's internal IP or does not listen.
|
||||
___ Detect network settings, make the other client server for file transfer (sending a second transfer-invite).
|
||||
___ Update the classic FileTransfer application to use the new async-cnnect, DirectConnectionPool and showTransfer*() API.
|
||||
|
||||
Critical bugs:
|
||||
___ Restore the documentation
|
||||
___ Restore the translations
|
||||
|
||||
Junior jobs:
|
||||
___ Improve wink playing, include preview, offer "play" button (also see other showWink() issues). Also fixes issues when chat is started with a wink.
|
||||
___ Implement phone settings (PRP and BPR fields).
|
||||
___ Implement privacy settings (GTC and BLP fields, messages like "can't chat with invited contact" because not in the AL).
|
||||
... And if you're up for a challenge, you could try one of the "Low priority protocol features" below too.
|
||||
... Or try to implement a new MSN feature (see "Future ideas" section).
|
||||
|
||||
Annoying bugs:
|
||||
___ Fix repeated picture transfer invitations when contact declines or aborts the invitation (preferably disable only for a few minutes).
|
||||
___ Automatically clean up the displaypics folder, and msnpicture-alias-##.png images that are older then 1 month.
|
||||
___ Add detection for NAK responses to file transfer invitations
|
||||
___ Improve performance of restyling the chat window: combine xml to one string.
|
||||
|
||||
Low-priority features:
|
||||
___ Improve wink processing messages of `cabextract` output in ChatWindow::showWink().
|
||||
___ When chat window closes, inform user the file transfers will also abort.
|
||||
___ See what happens when there is a picture transfer in a multi-chat, and one of the chats becomes busy.
|
||||
___ When opening chat windows, shift their position to make them cascade.
|
||||
|
||||
Low-priority code changes:
|
||||
___ Add Application::get..TransferAbortMessage().
|
||||
___ Only allow plugins/non-local files temporary when displaying winks?
|
||||
___ Implement Application::attachToChat(..) feature to improve aborting?
|
||||
___ Create a WinkArchive class for the code in ChatWindow::showWink().
|
||||
___ Include contact meta-data in receivedMessage() call of ChatWindow::showWink().
|
||||
|
||||
Low-priority protocol features:
|
||||
___ Support adding contacts to multiple groups.
|
||||
___ Detect multiple external IP addresses to advertise in file transfer invite message.
|
||||
___ Support sending the data-preparation ACK later with Windows Live Messenger picture transfers.
|
||||
___ Support direct connection setups when requesting contact pictures.
|
||||
___ Support aborting the data-preparation, also detect when contact does this.
|
||||
___ Support the datacast emulation over MSNP2P for MSNC1-compatible clients (for winks).
|
||||
___ Test whether applications need to be aborted when the switchboard reconnects.
|
||||
___ Check P2P incomingMessages_ / outgoingMessages_ cache for timeouts.
|
||||
___ Leave a P2PApplication half-open to receive a final error message.
|
||||
___ Use "URL PERSON/PROFILE" settings.
|
||||
|
||||
Wishes by users for 1.5:
|
||||
___ XMMS2 now listening: http://www.kmess.org/board/viewtopic.php?t=1569 (use relaytool from autopackage.org for that).

Future ideas:
|
||||
=============
|
||||
|
||||
MSN Protocol support:
|
||||
___ Improve old file transfer code, multiple connections like MSN5 does.
|
||||
___ Implement a settings category ("File transfers") where the user can at least choose:

GNU LESSER GENERAL PUBLIC LICENSE
|
||||
Version 2.1, February 1999
|
||||
|
||||
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
[This is the first released version of the Lesser GPL. It also counts
|
||||
as the successor of the GNU Library Public License, version 2, hence
|
||||
the version number 2.1.]
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
Licenses are intended to guarantee your freedom to share and change
|
||||
free software--to make sure the software is free for all its users.
|
||||
|
||||
This license, the Lesser General Public License, applies to some
|
||||
specially designated software packages--typically libraries--of the
|
||||
Free Software Foundation and other authors who decide to use it. You
|
||||
can use it too, but we suggest you first think carefully about whether
|
||||
this license or the ordinary General Public License is the better
|
||||
strategy to use in any particular case, based on the explanations below.
|
||||
|
||||
When we speak of free software, we are referring to freedom of use,
|
||||
not price. Our General Public Licenses are designed to make sure that
|
||||
you have the freedom to distribute copies of free software (and charge
|
||||
for this service if you wish); that you receive source code or can get
|
||||
it if you want it; that you can change the software and use pieces of
|
||||
it in new free programs; and that you are informed that you can do
|
||||
these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
distributors to deny you these rights or to ask you to surrender these
|
||||
rights. These restrictions translate to certain responsibilities for
|
||||
you if you distribute copies of the library or if you modify it.
|
||||
|
||||
For example, if you distribute copies of the library, whether gratis
|
||||
or for a fee, you must give the recipients all the rights that we gave
|
||||
you. You must make sure that they, too, receive or can get the source
|
||||
code. If you link other code with the library, you must provide
|
||||
complete object files to the recipients, so that they can relink them
|
||||
with the library after making changes to the library and recompiling
|
||||
it. And you must show them these terms so they know their rights.
|
||||
|
||||
We protect your rights with a two-step method: (1) we copyright the
|
||||
library, and (2) we offer you this license, which gives you legal
|
||||
permission to copy, distribute and/or modify the library.
|
||||
|
||||
To protect each distributor, we want to make it very clear that
|
||||
there is no warranty for the free library. Also, if the library is
|
||||
modified by someone else and passed on, the recipients should know
|
||||
that what they have is not the original version, so that the original
|
||||
author's reputation will not be affected by problems that might be
|
||||
introduced by others.
|
||||
|
||||
Finally, software patents pose a constant threat to the existence of
|
||||
any free program. We wish to make sure that a company cannot
|
||||
effectively restrict the users of a free program by obtaining a
|
||||
restrictive license from a patent holder. Therefore, we insist that
|
||||
any patent license obtained for a version of the library must be
|
||||
consistent with the full freedom of use specified in this license.
|
||||
|
||||
Most GNU software, including some libraries, is covered by the
|
||||
ordinary GNU General Public License. This license, the GNU Lesser
|
||||
General Public License, applies to certain designated libraries, and
|
||||
is quite different from the ordinary General Public License. We use
|
||||
this license for certain libraries in order to permit linking those
|
||||
libraries into non-free programs.
|
||||
|
||||
When a program is linked with a library, whether statically or using
|
||||
a shared library, the combination of the two is legally speaking a
|
||||
combined work, a derivative of the original library. The ordinary
|
||||
General Public License therefore permits such linking only if the
|
||||
entire combination fits its criteria of freedom. The Lesser General
|
||||
Public License permits more lax criteria for linking other code with
|
||||
the library.
|
||||
|
||||
We call this license the "Lesser" General Public License because it
|
||||
does Less to protect the user's freedom than the ordinary General
|
||||
Public License. It also provides other free software developers Less
|
||||
of an advantage over competing non-free programs. These disadvantages
|
||||
are the reason we use the ordinary General Public License for many
|
||||
libraries. However, the Lesser license provides advantages in certain
|
||||
special circumstances.
|
||||
|
||||
For example, on rare occasions, there may be a special need to
|
||||
encourage the widest possible use of a certain library, so that it becomes
|
||||
a de-facto standard. To achieve this, non-free programs must be
|
||||
allowed to use the library. A more frequent case is that a free
|
||||
library does the same job as widely used non-free libraries. In this
|
||||
case, there is little to gain by limiting the free library to free
|
||||
software only, so we use the Lesser General Public License.
|
||||
|
||||
In other cases, permission to use a particular library in non-free
|
||||
programs enables a greater number of people to use a large body of
|
||||
free software. For example, permission to use the GNU C Library in
|
||||
non-free programs enables many more people to use the whole GNU
|
||||
operating system, as well as its variant, the GNU/Linux operating
|
||||
system.
|
||||
|
||||
Although the Lesser General Public License is Less protective of the
|
||||
users' freedom, it does ensure that the user of a program that is
|
||||
linked with the Library has the freedom and the wherewithal to run
|
||||
that program using a modified version of the Library.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow. Pay close attention to the difference between a
|
||||
"work based on the library" and a "work that uses the library". The
|
||||
former contains code derived from the library, whereas the latter must
|
||||
be combined with the library in order to run.
|
||||
|
||||
GNU LESSER GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License Agreement applies to any software library or other
|
||||
program which contains a notice placed by the copyright holder or
|
||||
other authorized party saying it may be distributed under the terms of
|
||||
this Lesser General Public License (also called "this License").
|
||||
Each licensee is addressed as "you".
|
||||
|
||||
A "library" means a collection of software functions and/or data
|
||||
prepared so as to be conveniently linked with application programs
|
||||
(which use some of those functions and data) to form executables.
|
||||
|
||||
The "Library", below, refers to any such software library or work
|
||||
which has been distributed under these terms. A "work based on the
|
||||
Library" means either the Library or any derivative work under
|
||||
copyright law: that is to say, a work containing the Library or a
|
||||
portion of it, either verbatim or with modifications and/or translated
|
||||
straightforwardly into another language. (Hereinafter, translation is
|
||||
included without limitation in the term "modification".)
|
||||
|
||||
"Source code" for a work means the preferred form of the work for
|
||||
making modifications to it. For a library, complete source code means
|
||||
all the source code for all modules it contains, plus any associated
|
||||
interface definition files, plus the scripts used to control compilation
|
||||
and installation of the library.
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running a program using the Library is not restricted, and output from
|
||||
such a program is covered only if its contents constitute a work based
|
||||
on the Library (independent of the use of the Library in a tool for
|
||||
writing it). Whether that is true depends on what the Library does
|
||||
and what the program that uses the Library does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Library's
|
||||
complete source code as you receive it, in any medium, provided that
|
||||
you conspicuously and appropriately publish on each copy an
|
||||
appropriate copyright notice and disclaimer of warranty; keep intact
|
||||
all the notices that refer to this License and to the absence of any
|
||||
warranty; and distribute a copy of this License along with the
|
||||
Library.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy,
|
||||
and you may at your option offer warranty protection in exchange for a
|
||||
fee.
|
||||
|
||||
2. You may modify your copy or copies of the Library or any portion
|
||||
of it, thus forming a work based on the Library, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) The modified work must itself be a software library.
|
||||
|
||||
b) You must cause the files modified to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
c) You must cause the whole of the work to be licensed at no
|
||||
charge to all third parties under the terms of this License.
|
||||
|
||||
d) If a facility in the modified Library refers to a function or a
|
||||
table of data to be supplied by an application program that uses
|
||||
the facility, other than as an argument passed when the facility
|
||||
is invoked, then you must make a good faith effort to ensure that,
|
||||
in the event an application does not supply such function or
|
||||
table, the facility still operates, and performs whatever part of
|
||||
its purpose remains meaningful.
|
||||
|
||||
(For example, a function in a library to compute square roots has
|
||||
a purpose that is entirely well-defined independent of the
|
||||
application. Therefore, Subsection 2d requires that any
|
||||
application-supplied function or table used by this function must
|
||||
be optional: if the application does not supply it, the square
|
||||
root function must still compute square roots.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Library,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Library, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote
|
||||
it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Library.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Library
|
||||
with the Library (or with a work based on the Library) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may opt to apply the terms of the ordinary GNU General Public
|
||||
License instead of this License to a given copy of the Library. To do
|
||||
this, you must alter all the notices that refer to this License, so
|
||||
that they refer to the ordinary GNU General Public License, version 2,
|
||||
instead of to this License. (If a newer version than version 2 of the
|
||||
ordinary GNU General Public License has appeared, then you can specify
|
||||
that version instead if you wish.) Do not make any other change in
|
||||
these notices.
|
||||
|
||||
Once this change is made in a given copy, it is irreversible for
|
||||
that copy, so the ordinary GNU General Public License applies to all
|
||||
subsequent copies and derivative works made from that copy.
|
||||
|
||||
This option is useful when you wish to copy part of the code of
|
||||
the Library into a program that is not a library.
|
||||
|
||||
4. You may copy and distribute the Library (or a portion or
|
||||
derivative of it, under Section 2) in object code or executable form
|
||||
under the terms of Sections 1 and 2 above provided that you accompany
|
||||
it with the complete corresponding machine-readable source code, which
|
||||
must be distributed under the terms of Sections 1 and 2 above on a
|
||||
medium customarily used for software interchange.
|
||||
|
||||
If distribution of object code is made by offering access to copy
|
||||
from a designated place, then offering equivalent access to copy the
|
||||
source code from the same place satisfies the requirement to
|
||||
distribute the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
5. A program that contains no derivative of any portion of the
|
||||
Library, but is designed to work with the Library by being compiled or
|
||||
linked with it, is called a "work that uses the Library". Such a
|
||||
work, in isolation, is not a derivative work of the Library, and
|
||||
therefore falls outside the scope of this License.
|
||||
|
||||
However, linking a "work that uses the Library" with the Library
|
||||
creates an executable that is a derivative of the Library (because it
|
||||
contains portions of the Library), rather than a "work that uses the
|
||||
library". The executable is therefore covered by this License.
|
||||
Section 6 states terms for distribution of such executables.
|
||||
|
||||
When a "work that uses the Library" uses material from a header file
|
||||
that is part of the Library, the object code for the work may be a
|
||||
derivative work of the Library even though the source code is not.
|
||||
Whether this is true is especially significant if the work can be
|
||||
linked without the Library, or if the work is itself a library. The
|
||||
threshold for this to be true is not precisely defined by law.
|
||||
|
||||
If such an object file uses only numerical parameters, data
|
||||
structure layouts and accessors, and small macros and small inline
|
||||
functions (ten lines or less in length), then the use of the object
|
||||
file is unrestricted, regardless of whether it is legally a derivative
|
||||
work. (Executables containing this object code plus portions of the
|
||||
Library will still fall under Section 6.)
|
||||
|
||||
Otherwise, if the work is a derivative of the Library, you may
|
||||
distribute the object code for the work under the terms of Section 6.
|
||||
Any executables containing that work also fall under Section 6,
|
||||
whether or not they are linked directly with the Library itself.
|
||||
|
||||
6. As an exception to the Sections above, you may also combine or
|
||||
link a "work that uses the Library" with the Library to produce a
|
||||
work containing portions of the Library, and distribute that work
|
||||
under terms of your choice, provided that the terms permit
|
||||
modification of the work for the customer's own use and reverse
|
||||
engineering for debugging such modifications.
|
||||
|
||||
You must give prominent notice with each copy of the work that the
|
||||
Library is used in it and that the Library and its use are covered by
|
||||
this License. You must supply a copy of this License. If the work
|
||||
during execution displays copyright notices, you must include the
|
||||
copyright notice for the Library among them, as well as a reference
|
||||
directing the user to the copy of this License. Also, you must do one
|
||||
of these things:
|
||||
|
||||
a) Accompany the work with the complete corresponding
|
||||
machine-readable source code for the Library including whatever
|
||||
changes were used in the work (which must be distributed under
|
||||
Sections 1 and 2 above); and, if the work is an executable linked
|
||||
with the Library, with the complete machine-readable "work that
|
||||
uses the Library", as object code and/or source code, so that the
|
||||
user can modify the Library and then relink to produce a modified
|
||||
executable containing the modified Library. (It is understood
|
||||
that the user who changes the contents of definitions files in the
|
||||
Library will not necessarily be able to recompile the application
|
||||
to use the modified definitions.)
|
||||
|
||||
b) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (1) uses at run time a
|
||||
copy of the library already present on the user's computer system,
|
||||
rather than copying library functions into the executable, and (2)
|
||||
will operate properly with a modified version of the library, if
|
||||
the user installs one, as long as the modified version is
|
||||
interface-compatible with the version that the work was made with.
|
||||
|
||||
c) Accompany the work with a written offer, valid for at
|
||||
least three years, to give the same user the materials
|
||||
specified in Subsection 6a, above, for a charge no more
|
||||
than the cost of performing this distribution.
|
||||
|
||||
d) If distribution of the work is made by offering access to copy
|
||||
from a designated place, offer equivalent access to copy the above
|
||||
specified materials from the same place.
|
||||
|
||||
e) Verify that the user has already received a copy of these
|
||||
materials or that you have already sent this user a copy.
|
||||
|
||||
For an executable, the required form of the "work that uses the
|
||||
Library" must include any data and utility programs needed for
|
||||
reproducing the executable from it. However, as a special exception,
|
||||
the materials to be distributed need not include anything that is
|
||||
normally distributed (in either source or binary form) with the major
|
||||
components (compiler, kernel, and so on) of the operating system on
|
||||
which the executable runs, unless that component itself accompanies
|
||||
the executable.
|
||||
|
||||
It may happen that this requirement contradicts the license
|
||||
restrictions of other proprietary libraries that do not normally
|
||||
accompany the operating system. Such a contradiction means you cannot
|
||||
use both them and the Library together in an executable that you
|
||||
distribute.
|
||||
|
||||
7. You may place library facilities that are a work based on the
|
||||
Library side-by-side in a single library together with other library
|
||||
facilities not covered by this License, and distribute such a combined
|
||||
library, provided that the separate distribution of the work based on
|
||||
the Library and of the other library facilities is otherwise
|
||||
permitted, and provided that you do these two things:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work
|
||||
based on the Library, uncombined with any other library
|
||||
facilities. This must be distributed under the terms of the
|
||||
Sections above.
|
||||
|
||||
b) Give prominent notice with the combined library of the fact
|
||||
that part of it is a work based on the Library, and explaining
|
||||
where to find the accompanying uncombined form of the same work.
|
||||
|
||||
8. You may not copy, modify, sublicense, link with, or distribute
|
||||
the Library except as expressly provided under this License. Any
|
||||
attempt otherwise to copy, modify, sublicense, link with, or
|
||||
distribute the Library is void, and will automatically terminate your
|
||||
rights under this License. However, parties who have received copies,
|
||||
or rights, from you under this License will not have their licenses
|
||||
terminated so long as such parties remain in full compliance.
|
||||
|
||||
9. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Library or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Library (or any work based on the
|
||||
Library), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Library or works based on it.
|
||||
|
||||
10. Each time you redistribute the Library (or any work based on the
|
||||
Library), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute, link with or modify the Library
|
||||
subject to these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties with
|
||||
this License.
|
||||
|
||||
11. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Library at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Library by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Library.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under any
|
||||
particular circumstance, the balance of the section is intended to apply,
|
||||
and the section as a whole is intended to apply in other circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
12. If the distribution and/or use of the Library is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Library under this License may add
|
||||
an explicit geographical distribution limitation excluding those countries,
|
||||
so that distribution is permitted only in or among countries not thus
|
||||
excluded. In such case, this License incorporates the limitation as if
|
||||
written in the body of this License.
|
||||
|
||||
13. The Free Software Foundation may publish revised and/or new
|
||||
versions of the Lesser General Public License from time to time.
|
||||
Such new versions will be similar in spirit to the present version,
|
||||
but may differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Library
|
||||
specifies a version number of this License which applies to it and
|
||||
"any later version", you have the option of following the terms and
|
||||
conditions either of that version or of any later version published by
|
||||
the Free Software Foundation. If the Library does not specify a
|
||||
license version number, you may choose any version ever published by
|
||||
the Free Software Foundation.
|
||||
|
||||
14. If you wish to incorporate parts of the Library into other free
|
||||
programs whose distribution conditions are incompatible with these,
|
||||
write to the author to ask for permission. For software which is
|
||||
copyrighted by the Free Software Foundation, write to the Free
|
||||
Software Foundation; we sometimes make exceptions for this. Our
|
||||
decision will be guided by the two goals of preserving the free status
|
||||
of all derivatives of our free software and of promoting the sharing
|
||||
and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
||||
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
||||
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
||||
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
||||
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
||||
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
||||
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
||||
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
||||
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
||||
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
||||
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
||||
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
||||
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
||||
DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Libraries
|
||||
|
||||
If you develop a new library, and you want it to be of the greatest
|
||||
possible use to the public, we recommend making it free software that
|
||||
everyone can redistribute and change. You can do so by permitting
|
||||
redistribution under these terms (or, alternatively, under the terms of the
|
||||
ordinary General Public License).
|
||||
|
||||
To apply these terms, attach the following notices to the library. It is
|
||||
safest to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least the
|
||||
"copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the library's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This library is free software; you can redistribute it and/or
|
||||
modify it under the terms of the GNU Lesser General Public
|
||||
License as published by the Free Software Foundation; either
|
||||
version 2.1 of the License, or (at your option) any later version.
|
||||
|
||||
This library is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
|
||||
Lesser General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU Lesser General Public
|
||||
License along with this library; if not, write to the Free Software
|
||||
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the library, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the
|

library `Frob' (a library for tweaking knobs) written by James Random Hacker.

GNU LESSER GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates
|
||||
the terms and conditions of version 3 of the GNU General Public
|
||||
License, supplemented by the additional permissions listed below.
|
||||
|
||||
0. Additional Definitions.
|
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser
|
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
||||
General Public License.
|
||||
|
||||
"The Library" refers to a covered work governed by this License,
|
||||
other than an Application or a Combined Work as defined below.
|
||||
|
||||
An "Application" is any work that makes use of an interface provided
|
||||
by the Library, but which is not otherwise based on the Library.
|
||||
Defining a subclass of a class defined by the Library is deemed a mode
|
||||
of using an interface provided by the Library.
|
||||
|
||||
A "Combined Work" is a work produced by combining or linking an
|
||||
Application with the Library. The particular version of the Library
|
||||
with which the Combined Work was made is also called the "Linked
|
||||
Version".
|
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the
|
||||
Corresponding Source for the Combined Work, excluding any source code
|
||||
for portions of the Combined Work that, considered in isolation, are
|
||||
based on the Application, and not on the Linked Version.
|
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the
|
||||
object code and/or source code for the Application, including any data
|
||||
and utility programs needed for reproducing the Combined Work from the
|
||||
Application, but excluding the System Libraries of the Combined Work.
|
||||
|
||||
1. Exception to Section 3 of the GNU GPL.
|
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License
|
||||
without being bound by section 3 of the GNU GPL.
|
||||
|
||||
2. Conveying Modified Versions.
|
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a
|
||||
facility refers to a function or data to be supplied by an Application
|
||||
that uses the facility (other than as an argument passed when the
|
||||
facility is invoked), then you may convey a copy of the modified
|
||||
version:
|
||||
|
||||
a) under this License, provided that you make a good faith effort to
|
||||
ensure that, in the event an Application does not supply the
|
||||
function or data, the facility still operates, and performs
|
||||
whatever part of its purpose remains meaningful, or
|
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of
|
||||
this License applicable to that copy.
|
||||
|
||||
3. Object Code Incorporating Material from Library Header Files.
|
||||
|
||||
The object code form of an Application may incorporate material from
|
||||
a header file that is part of the Library. You may convey such object
|
||||
code under terms of your choice, provided that, if the incorporated
|
||||
material is not limited to numerical parameters, data structure
|
||||
layouts and accessors, or small macros, inline functions and templates
|
||||
(ten or fewer lines in length), you do both of the following:
|
||||
|
||||
a) Give prominent notice with each copy of the object code that the
|
||||
Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
4. Combined Works.
|
||||
|
||||
You may convey a Combined Work under terms of your choice that,
|
||||
taken together, effectively do not restrict modification of the
|
||||
portions of the Library contained in the Combined Work and reverse
|
||||
engineering for debugging such modifications, if you also do each of
|
||||
the following:
|
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that
|
||||
the Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
c) For a Combined Work that displays copyright notices during
|
||||
execution, include the copyright notice for the Library among
|
||||
these notices, as well as a reference directing the user to the
|
||||
copies of the GNU GPL and this license document.
|
||||
|
||||
d) Do one of the following:
|
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this
|
||||
License, and the Corresponding Application Code in a form
|
||||
suitable for, and under terms that permit, the user to
|
||||
recombine or relink the Application with a modified version of
|
||||
the Linked Version to produce a modified Combined Work, in the
|
||||
manner specified by section 6 of the GNU GPL for conveying
|
||||
Corresponding Source.
|
||||
|
||||
1) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (a) uses at run time
|
||||
a copy of the Library already present on the user's computer
|
||||
system, and (b) will operate properly with a modified version
|
||||
of the Library that is interface-compatible with the Linked
|
||||
Version.
|
||||
|
||||
e) Provide Installation Information, but only if you would otherwise
|
||||
be required to provide such information under section 6 of the
|
||||
GNU GPL, and only to the extent that such information is
|
||||
necessary to install and execute a modified version of the
|
||||
Combined Work produced by recombining or relinking the
|
||||
Application with a modified version of the Linked Version. (If
|
||||
you use option 4d0, the Installation Information must accompany
|
||||
the Minimal Corresponding Source and Corresponding Application
|
||||
Code. If you use option 4d1, you must provide the Installation
|
||||
Information in the manner specified by section 6 of the GNU GPL
|
||||
for conveying Corresponding Source.)
|
||||
|
||||
5. Combined Libraries.
|
||||
|
||||
You may place library facilities that are a work based on the
|
||||
Library side by side in a single library together with other library
|
||||
facilities that are not Applications and are not covered by this
|
||||
License, and convey such a combined library under terms of your
|
||||
choice, if you do both of the following:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work based
|
||||
on the Library, uncombined with any other library facilities,
|
||||
conveyed under the terms of this License.
|
||||
|
||||
b) Give prominent notice with the combined library that part of it
|
||||
is a work based on the Library, and explaining where to find the
|
||||
accompanying uncombined form of the same work.
|
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU Lesser General Public License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Library as you received it specifies that a certain numbered version
|
||||
of the GNU Lesser General Public License "or any later version"
|
||||
applies to it, you have the option of following the terms and
|
||||
conditions either of that published version or of any later version
|
||||
published by the Free Software Foundation. If the Library as you
|
||||
received it does not specify a version number of the GNU Lesser
|
||||
General Public License, you may choose any version of the GNU Lesser
|
||||
General Public License ever published by the Free Software Foundation.
|
||||
|
||||
If the Library as you received it specifies that a proxy can decide
|
||||
whether future versions of the GNU Lesser General Public License shall
|
||||
apply, that proxy's public statement of acceptance of any version is
|
||||
permanent authorization for you to choose that version for the
|
||||
Library.

* Fixed the copy constructor in Stroke, it was not copying all the necessary properties.
|
||||
* Fixed some compiler warnings.
|
||||
* Improved bundled compilation mode.
|
||||
|
||||
2010-07-22 (Valerio)
|
||||
* Improved the InkEdit text - added a checkbox to show the usage of Canvas::isEmpty() and a label
|
||||
to show usage of the Canvas::inkChanged() signal.
|
||||
* Fixed inkChanged() signal emission in Canvas: it was emitted too early, when the drawing was not
|
||||
updated yet: slots connected to inkChanged() could then call isEmpty() and get a true return value,
|
||||
even if the drawing wasn't empty.
|

* Use Q_ASSERT_X instead of qWarning where appropriate.
|

* Changed the default behavior of InkCanvas::pixmap(), now paints on a transparent
|
||||
background, instead of a white one.
|
||||
|
||||
2010-06-19 (Valerio)
|
||||
* Added support for PNG fortification. Like GIF fortification, this feature allows to
|
||||
write a PNG containing the full ISF drawing inside itself. Of course, it's now also
|
||||
possible to read a PNG containing ISF data and retrieve the actual drawing.
|
||||
|
||||
2010-03-20 (Adam)
|
||||
* Slight optimisation to painting - we no longer draw the background color, Qt does it for us.
|
||||
Also, only render the parts of the buffer that have changed.
|
||||
|
||||
2010-03-13 (Adam)
|
||||
* Add a bezier curve smoothing algorithm. Strokes with the FitToCurve flag set are
|
||||
rendered with an approximate bezier curve. Gives much smoother looking strokes.
|
||||
|
||||
2010-02-21 (Adam)
|
||||
* Optimise the painting of strokes. Cache logic added to IsfQtDrawing and only
|

strokes that have been added are painted. Also, no longer do a full bounding rect
|
||||
recalculation when a stroke is added.
|

* Added Fortified GIF read-write support. New optional dependency, giflib.
|
||||
* Added Base64-encoded input/output data support.
|
||||
* Updated the documentation files.
|
||||
* Added Doxygen documentation infrastructure. There still are a lot of errors.
|

* Rewritten the algorithm detection methods.
|
||||
* Changed the names of some internal data classes, and improved their namespaces.
|

* Added a maximum drawing size check, to avoid errors from resulting in 80k by 70k pixel wide
|

drawings.
|
||||
* Moved all algorithms into src/data/algorithms.
|
||||
* Renamed the Gorilla algorithm to "Bit Packing".
|

* Separated the delta-delta transformation methods into their own files.

||||
* Added an algorithm to do bit-packing of bytes.
|
||||
* Fixed bug in DataSource, the last bit of data was never read.
|
||||
* Added parsing the GUID table tag and saving the GUIDs into Drawing.
|
||||
* Added parsing of custom tags and decoding their contents.
|
||||
|
||||
2009-08-29 (Valerio)
|
||||
* Fixed skipping unknown custom tags contents.
|
||||
* Changed more method names to adhere to Qt's method naming style.
|
||||
|
||||
2009-08-29 (Adam)
|
||||
* Start qt-ifying the function names ie, "penSize()" instead of "getPenSize()".
|
||||
* Add methods to return pen size, colour and brush type from InkCanvas.
|
||||
* Always write at least one transformation to the stream: if no custom transforms, write the default one.
|
||||
* No longer take ownership of Isf::Drawing instances set with setDrawing().
|
||||
* By default InkCanvas' initial Isf::Drawing instance that is created is no longer allocated
|
||||
with new. This frees us from the concern of "when do we delete this initial reference?".
|
||||
* Rename Isf::InkEdit to Isf::InkCanvas. A better suited name.
|
||||
* When building bundled isf-qt, link statically and do not install any library components.
|
||||
Non-bundled builds a shared library and installs all components.
|
||||
|
||||
2009-08-28 (Adam)
|
||||
* Fix writing of transformation data: write in the correct order and scale the transform values
|
||||
appropriately before writing.
|
||||
* Write TIDX properly when transformations change between strokes.
|
||||
* Properly apply scaling when calculating the bounding rectangle.
|
||||
* Do not use Compress.decode(*) calls as function parameters. The order of parameter
|
||||
evaluation is platform-dependent and hence cannot be relied on.
|
||||
* Properly apply stroke transforms when drawing; scale pen size appropriately.
|
||||
|
||||
2009-08-24 (Adam)
|
||||
* Fix Drawing::getStrokeAtPoint to properly return point strokes.
|
||||
* Prevent strokes from having a bounding rectangle of size 1x1 (otherwise the eraser never hit them)
|
||||
* Tweak the collision distance to give a 25% margin of error (in practice this works well).
|
||||
|
||||
2009-08-23 (Adam)
|
||||
* Add Drawing::getStrokeAtPoint method. Uses Heron's Formula and triangle heights to determine
|
||||
if the cursor is positioned above a stroke. Seems to work quite well and appears to be fast.
|
||||
* Basic eraser support working. Individual strokes can be erased.
|
||||
* InkEdit now shows a custom cursor - a point drawn with the current stroke colour and width.
|
||||
* Drawing now calculates its bounding rectangle as necessary. Calls to finalizeChanges are not
|
||||
necessary anymore.
|
||||
* Remove cropping. Found a better method whereby InkEdit will draw the rendered ISF using the
|
||||
offset provided by the bounding rectangle of Isf::Drawing.
|
||||
* Supply the FitToCurve flag for all strokes. Windows will render them using Bezier smoothing, making
|
||||
them appear nicer.
|
||||
* Upgrade the TestInkEdit application. Supports multiple stroke colours and pen widths.
|
||||
* Remove InkEdit::getImageBytes and replace with InkEdit::getBytes. InkEdit doesn't write to GIF.
|
||||
* Support changing the colour of the InkEdit canvas.
|
||||
* Add a convenience method, InkEdit::save(), that will write the ISF drawing to a given QIODevice.
|
||||
Optionally will write the drawing in base64.
|
||||
|
||||
2009-08-23 (Adam)
|
||||
* Bug fixes in isf-qt: properly assign stroke attributes when changing colour on InkEdit.
|
||||
* Fix a crash that would occur if stroke attributes or transform were null.
|
||||
* Initial version of isf-qt InkEdit committed. Works reasonably well. Not integrated in KMess yet.
|
||||
* Added a cropping property to Isf::Drawing. When true, Drawing::getImage returns a cropped image
|
||||
and getSize returns the cropped size. When false, does the opposite. Necessary for InkEdit to
|
||||
properly support adding strokes to loaded Ink data.
|
||||
* Add a test application for new InkEdit. Can create, save and load Ink data in both raw ISF and
|
||||
ISF-base64 format.
|
||||
* Fix a bug in tagswriter which cause corrupt ISF data if there were no metric blocks.
|
||||
|
||||
2009-08-20 (Valerio)
|
||||
* Implemented writing metric blocks into ISF streams.
|
||||
* Fixed transformation/attributeSet/metrics index writing, now the index tags are written only
|
||||
when necessary.
|
||||
* Removed all user-side required conversions between HiMetric units and pixels. The library
|
||||
now only offers data expressed in pixels.
|
||||
* Fixed a bug in writeHiMetricSize() which prevented ISF streams from being parsed by older
|
||||
Microsoft.Ink libraries, like the one of Windows Messenger.
|
||||
|
||||
2009-08-20 (Adam)
|
||||
* Fix install path of FindIsfQt.cmake.
|
||||
* Don't attempt to install FindIsfQt.cmake if the library is build bundled.
|
||||
|
||||
2009-08-19 (Valerio)
|
||||
* Added DataSource::reset() method to start reading data back from the start.
|
||||
* Added to DataSource some ways to detect errors.
|
||||
* Rewritten the multi-byte encoding tests.
|
||||
* Switched away from QTransform to QMatrix for transformations.
|
||||
* Fixed the write order of transformation values.
|
||||
* Fixed stroke saving. The library should now be able to generate new ink.
|
||||
* Renamed Isf::Parser::isfToDrawing() and Isf::Parser::drawingToIsf()
|
||||
to Isf::Stream::reader() and Isf::Stream::writer() to enhance readability.
|
||||
* Renamed the Isf::PointInfo structure to Isf::AttributeSet, because the old name made no sense.
|
||||
* Added manipulation methods for strokes, transformations and attribute sets.
|
||||
* Fixed compiler warning. Thanks to Émeric Dupont.
|
||||
* Fixed colors in written streams.
|
||||
* Fixed the Scale&Translate transformation once again.
|
||||
* Isf::Drawings are now created on the heap instead of on the stack, to avoid unwanted object
|
||||
deletions.
|
||||
* Added optional parameter to Isf::Drawing::getPixmap() to choose the background color of
|
||||
the created image.
|
||||
* Added a method to compute some useful values before rendering new and changed drawings.
|
||||
* Added a couple stream writer improvements.
|
||||
|
||||
2009-08-14 (Valerio)
|
||||
* Added Drawing::clean() method to reset a drawing without creating a new one.
|
||||
|
||||
2009-08-13 (Valerio)
|
||||
* Added DataSource method to append bit arrays to the data.
|
||||
* Implemented Huffman encoding. Still missing is the algo to select the best encoding index.
|
||||
|
||||
2009-08-07 (Valerio)
|
||||
* Added an AUTHORS file with credits.
|
||||
* Implemented Gorilla compression.
|
||||
* Added stroke writing in the stream writer.
|
||||
* Moved all of Drawing's object lists to pointer lists, to ease comparing their items.
|
||||
|
||||
2009-08-06 (Valerio)
|
||||
* Added Metrics recognization and saving.
|
||||
* Made sense into the property tags: they're now all in the PacketProperty enum.
|
||||
* Added MultiByteCoding utility methods to find out the encoded size of a value.
|
||||
* Changed the installed include files directory to PREFIX/include/isf-qt .
|
||||
* Added a NOTES file with possibly useful stuff.
|
||||
* Added metrics measurement units, found on MSDN.
|
||||
* Added a couple more checks on data.
|
||||
* Moved include isfdrawing.h to isfqtdrawing.h .
|
||||
* Fixed CMake installing bug and added C++ style includes, <IsfQt> and <IsfQtDrawing>.
|
||||
* Fixed name of the drawing-to-isf converting method.
|
||||
* Fixed crash when given an invalid drawing address.
|
||||
|
||||
2009-08-05 (Valerio)
|
||||
* Extended Adam's last fix to the other main drawing properties.
|
||||
* Added maximum stroke pen size value.
|
||||
* Added stroke and drawing bounding box values.
|
||||
* Added adjusting the drawing's bounding box to include thick strokes.
|
||||
* Enabled transformations.
|
||||
* Fixed transform data order, it was inverted for scale+translate transforms.
|
||||
* Fixed destination QPixmap's size, it's now fit for the drawing.
|
||||
* Completed CMake rules, now the library can be installed on the system and
|
||||
other projects can find it.
|
||||
* Improved debugging rules, now debug mode is controlled (again) from CMake
|
||||
and verbose output is configurable.
|
||||
* Fixed the documentation to reflect the name change "libisf" to "isf-qt",
|
||||
and updated it.
|
||||
* Added updated KDevelop3/4 project files.
|
||||
* Changed the library structure:
|
||||
- separated the public interface includes into the /include/ dir
|
||||
- moved all internally used inclusions and data structures into
|
||||
/src/isfqt-internal.h
|
||||
- reorganized the internal files structure
|
||||
- renamed class Tags to TagsParser as there will be a TagWriter (made up name)
|
||||
- Renamed the IsfData class to DataSource as it is at a lower level than ISF.
|
||||
- Moved the ISF parser into a class Parser, found in include/isfqt.h and src/isfqt.cpp
|
||||
* Added a dummy drawing-to-ISF method in class Parser.
|
||||
* Added multibyte encoding methods taking a DataSource.
|
||||
* Added float encoding method and fixed uint encoding method.
|
||||
* Fixed seeking bug in DataSource::append() methods.
|
||||
* Added DataSource::prepend() methods.
|
||||
* Started working on the ISF stream writer.
|
||||
|
||||
2009-08-05 (Adam)
|
||||
* Correct an issue with incorrect colours for strokes.
|
||||
|
||||
2009-08-04 (Adam)
|
||||
* Re-save test ISF data with official Microsoft Ink classes.
|
||||
* Add functions to convert between HiMetric units and pixels.
|
||||
* Antialiasing whilst drawing ISF to QPixmap.
|
||||
* Fix the drawing of ISF data to QPixmap: draw the lines correctly between points.
|
||||
|
||||
2009-08-04 (Valerio)
|
||||
* Fixed endianness problems when retrieving datastream bits with IsfData.
|
||||
* Added a new parameter to IsfData::atEnd() to check if the buffer was all used,
|
||||
including the current byte's bits.
|
||||
* Changed IsfData::seekByteBack() with seekRelative(), which makes more sense.
|
||||
* Added IsfData::skipToNextByte() to discard the current byte's bits and move on
|
||||
to the next byte.
|
||||
* Added Isf::Drawing method getPixmap() to convert a drawing to a QPixmap. Quite raw
|
||||
at the moment, but still.
|
||||
* Moved actual tag parsing into Isf::Drawing::parseTag().
|
||||
* Added a whole lot of tags to Isf::Tags. Now the parser is able to recognize the most
|
||||
useful tags (and mostly make use of their data).
|
||||
* Added a GUID mapping from the ISF specs, I doubt it'll ever be used though.
|
||||
* Added float decoding method to multibytecoding.cpp.
|
||||
* Added new test ISF files - more complex - and sorted all test ISF files by complexity.
|
||||
* Added new test application "test_decode", which displays a parsed ISF file.
|
||||
* Added pressure data recognization.
|
||||
* Added stroke description blocks recognization.
|
||||
* Fixed stroke payload parsing appearing when not needed (and wasting bytes).
|
||||
* Added a set of data structures to hold metrics and to better contain stroke attributes.
|
||||
* Reorganized the code of the Tags namespace, it's now a class with all static members;
|
||||
this simplifies quite a bit the passing of data between that and IsfDrawing.
|
||||
* Fixed bug in the GUID Table tag parser.
|
||||
* Added more compiler flags (and warnings) to ease debugging.
|
||||
* Added the infrastructure to link metrics and transforms data to the strokes.
|
||||
* Finally linked the drawing attributes and stroke info to the strokes' data:
|
||||
libisf-qt is now correctly decoding all tests (except test 6).
|
||||
* Fixed all compiler warnings and improved the debugging output.
|
||||
* Fixed point rendering didn't work when points are made by a line from a point
|
||||
to the same point.
|
||||
* Fixed broken main parser loop, continued forever.
|
||||
|
||||
2009-07-30 (Valerio)
|
||||
* Added IsfData class to read and write bit-by-bit an array of bytes.
|
||||
* Changed all the code to use it instead of plain QByteArrays.
|
||||
* Completed huffman decompression support.
|
||||
* Added algorithm data to help writing gorilla decompression.
|
||||
* Added tests for the IsfData class.
|
||||
* Added tag recognization.
|
||||
* Fixed some IsfData bugs.
|
||||
* Changed default CMake build type to debugfull.
|
||||
* Completed Gorilla decompression support.
|
||||
* Started tag parsing work, made basic analysis methods.
|
||||
* Made the ParserError enum (now IsfError) the library's error enumeration system.
|
||||
* Continued a bit the tag parsing work, added a couple tags and another testfile.
|
||||
|
||||
2009-07-08 (Adam)
|
||||
* Make decode(UInt|Int) take a reference as a position parameter. This
|
||||
reference is then incremented as the integer is decoded.
|
||||
* Re-work tests for IsfDrawing.
|
||||
* Create IsfDrawing::fromIsfData() static method to create a new IsfDrawing
|
||||
instance from a QByteArray containing ISF data.
|
||||
* Begin state matchine for ISF parser.
|
||||
* Add appropriate unit tests for ISF parser.
|
||||
* Added TODO file for libisf to keep track of things.
|
||||
|
||||
2009-06-30 (Adam)
|
||||
* Parse ISF version number properly; add unit tests for it.
|
||||
* Fix CMakeLists.txt to build with debug info by default
|
||||
* Moved format/types.(cpp|h) into the multibytecoding.(cpp|h) classes.
|
||||
Also moved these into libisf/ and deleted format/ directory.
|
||||
* Added Isf::encodeInt to encode a signed integer into multibyte format
|
||||
* Added test cases for the encode/decode functions.
|
||||
* Re-add libisf.h
|
||||
* Fix wrong e-mail addresses in copyright info.
|
||||
* Created a unit test framework for libisf-qt; run using make test
|
||||
* Created IsfDrawing class which will represent an ISF drawing.
|
||||
* Added some rudimentary unit tests for IsfDrawing

To save received ISF from Messenger, put this code in src/chat/chatmaster.cpp at line 1324, below "case FORMAT_ISF:" but above the "break;":

QFile file( "~/output.isf" );

file.write( QByteArray::fromBase64( inkEncodedData ) );

file.close();

You probably have to change the file path :P

About LibISF-Qt:
|
||||
============
|
||||
|
||||
LibISF-Qt is a Qt4 library made to encode and decode Microsoft's
|
||||
Ink Serialized Format (ISF) files.
|
||||
|
||||
Q. What is ISF?
|
||||
A. Ink Serialized Format is an open specification initially
|
||||
made by Microsoft, and then freed up with their "Open
|
||||
Specification Promise" initiative. ISF is a file format
|
||||
made to store handwriting very efficiently: an ISF file
|
||||
with a somewhat complex handwritten drawing takes less than
|
||||
1000 bytes. ISF supports metrics to adapt drawings to
|
||||
different form factors, bezier smoothing of drawn strokes,
|
||||
coloring, stroke size varying by pen pressure, linking
|
||||
in static data, and more.
|
||||
|
||||
Q. How does this library differ from aMSN's or Emesene's?
|
||||
A. It's written with Qt, which makes it easily portable on
|
||||
a lot of different architectures; also Qt's new licensing
|
||||
terms (LGPL) make it possible for everyone to use it
|
||||
easily.
|
||||
The library supports more ISF features than those two,
|
||||
since we've written it using the official specification.
|
||||
Moreover, aMSN's and Emesene's are not distributed by
|
||||
theirselves, ours is.
|
||||
|
||||
Q. What's the status of completion of the library, and which
|
||||
ISF features does/will support?
|
||||
A. Please see the TODO file to have an overview.
|
||||
|
||||
|
||||
|
||||
Compiling and installing:
|
||||
=================
|
||||
|
||||
LibISF-Qt uses CMake, a quick and clean alternative to Autotools.
|
||||
|
||||
First create a new directory within the one which contains this
|
||||
file (we'll have the library built there):
|
||||
$ mkdir build
|
||||
Enter it and run CMake:
|
||||
$ cd build
|
||||
$ cmake -D CMAKE_INSTALL_PREFIX=/usr ..
|
||||
Then, if everything went smoothly, build the library itself:
|
||||
$ make
|
||||
If everything went right again, install it:
|
||||
$ make install
|
||||
Aaand now you're set. :)
|
||||
|
||||
LibISF-Qt natively supports being bundled into other applications.
|
||||
Bundling means that the library does not get installed system-wide
|
||||
along with your application, but instead it gets statically linked
|
||||
into the application.
|
||||
The idea is that you copy the Isf-Qt source tree (with an SVN export
|
||||
or a Git submodule) into your project's tree, and then set up your
|
||||
CMake listfile to add this library as a subdirectory:
|
||||
> SET( ISFQT_IS_BUNDLED TRUE )
|
||||
> ADD_SUBDIRECTORY( contrib/isf-qt )
|
||||
And again, you're done!
|
||||
|
||||
|
||||
Documentation:
|
||||
=================
|
||||
|
||||
The ISF format is (albeit poorly*) documented: here's the
|
||||
sources we used.
|
||||
|
||||
- Original Microsoft ISF specification, made open with their
|
||||
Open Specification Promise:
|
||||
http://download.microsoft.com/download/0/B/E/0BE8BDD7-E5E8-422A-ABFD-4342ED7AD886/InkSerializedFormat(ISF)Specification.pdf
|
||||
- Quick explanation of the algorithms and other very useful
|
||||
details:
|
||||
http://synce.org/moin/FormatDocumentation/InkSerializedFormat
|
||||
- Original code from aMSN:
|
||||
https://amsn.svn.sourceforge.net/svnroot/amsn/trunk/amsn/utils/tclISF/src
|
||||
- Original code from emesene:
|
||||
https://emesene.svn.sourceforge.net/svnroot/emesene/trunk/emesene/pyisf
|
||||
|
||||
* = The specification was probably not meant for use by
|
||||
developers wanting to write an alternative implementation;
|
||||
there's a lot of guesswork to be done.
|
||||
|
||||
|
||||
|
||||
Licensing
|
||||
=========
|
||||
|
||||
Only the Oxygen icon, draw-eraser, is released under LGPL 3.0 (see http://www.oxygen-icons.org/). See COPYING_ICONS for full license text.
|
||||
|
||||
The remainder of ISF-qt is released under LGPL2.1. See COPYING for full license text.

|

* @brief This is a control designed for the drawing and display of Ink.
|
||||
*
|
||||
* InkCanvas is used for drawing and displaying Ink. The currently displayed Ink drawing can be retrieved
|
||||
* or set using the drawing() and setDrawing() methods.
|
||||
*
|
||||
* To set the properties of the current pen, use the setPenColor(), setPenSize() and setPenType() methods.
|
||||
* The supported pen types are outlined in the PenType enumeration documentation.
|
||||
*
|
||||
* Example:
|
||||
*
|
||||
* \code
|
||||
* InkCanvas* canvas = new Isf::InkCanvas( this );
|
||||
* canvas->setPenColor( Qt::blue );
|
||||
* canvas->setPenSize( 10 );
|
||||
*
|
||||
* // the pen is now 10 pixels thick and blue.
|
||||
*
|
||||
* canvas->setPenType( EraserPen );
|
||||
*
|
||||
* // now an eraser will be used and strokes can be erased individually.
|
||||
* \endcode
|
||||
*
|
||||
* To return the currently displayed Ink as a QImage, use image(). To return the raw ISF data, suitable
|
||||
* for saving to disk or sending over a network, use bytes().
|
||||
*
|
||||
* To write the ISF data directly to a QIODevice, such as a file, use the save() method.
|
||||
*
|
||||
* Connect to the inkChanged() signal to be notified when the drawing displayed on the canvas changes,
|
||||
* either through strokes being drawn or deleted, or the current drawing being changed.

* @mainpage ISF-Qt - Ink Serialized Format library
|
||||
*
|
||||
* @section about About ISF-Qt
|
||||
*
|
||||
* ISF-Qt is a library, written in C++ with the Qt 4 toolkit, capable of reading
|
||||
* and writing the ISF format. ISF stands for "Ink Serialized Format", and is
|
||||
* the disk serialization format used by the Windows.Ink C# library and by the
|
||||
* TabletPC platform, but also by applications like Windows Live Messenger - which
|
||||
* uses ISF to transfer handwriting messages.
|
||||
*
|
||||
* We had the need to interpret these handwriting messages in the best possible
|
||||
* way, and started to reverse-engineer the format, with the help of existing
|
||||
* (but incomplete) libraries and specifications. What we ended up with is ISF-Qt,
|
||||
* a library which can be used to decode an ISF file or data stream, manage it
|
||||
* and the the strokes which comprise the drawing, and write ISF files/streams.
|
||||
* You can also create new drawings from scratch.
|
||||
*
|
||||
*
|
||||
* @section intro About this documentation
|
||||
* This documentation is written towards developers, to be used
|
||||
* as reference manual when writing code which uses ISF-Qt, or when developing
|
||||
* the library itself.
|
||||
* Please take your time to understand the structure of the library, its classes
|
||||
* and methods.
|
||||
*
|
||||
* Since ISF-Qt is built on top of the Qt 4 library, you will also need to
|
||||
* be familiar with it; more information can be found online at:
|
||||
* - http://doc.trolltech.com/4.3/index.html

Here's how this algorithm works:

1) Iterate through strokes in reverse order.

2) For each stroke, check if the bounding rectangle contains the point where the cursor is.
|
||||
If not, continue to the next stroke. Prevents us checking all the strokes.
|
||||
3) Next, iterate through each pair of points in the stroke. If both of the points fall outside
|
||||
of the searching rectangle around the cursor, skip. Saves us checking hundreds of points when
|
||||
only a few will do.
|
||||
4) a) For each pair of strokes, form a triangle whose points are defined by the two points for the
|
||||
line segment, plus the cursor position.
|
||||
b) Calculate the height of this triangle. To do so, use Heron's Formula plus the formula for the
|
||||
area of any triangle.
|
||||
c) If the cursor is touching the drawn stroke, the height should be less than or equal to the
|
||||
half-width of the pen that drew the stroke.
|
||||
|
||||
For reference (triangle sides a, b, c, height h)
|
||||
Heron's Formula: area = sqrt(s * (s - a) * (s - b) * (s - c) ), where s = semiperimeter = 0.5*(a+b+c)
|
||||
area = 0.5*base*height;
