I'm pleased to announce that version 1.11.1 of LPROF is now available.  LPROF is an open source application that will create ICC profiles for use with other applications such as Scribus, CinePaint, Krita, UFRAW and the development version of GIMP. This is the second development snap shot of the work that has been underway since LPROF became a SourceForge project.  Please see  the LPROF SourceForge web pages http://sourceforge.net/projects/lprof for details.

This is a development snap shot of what will become version 1.12 when it is stable.  Although testing by the development team indicates that this snap shot appears to be stable it is a development release and as such it should not considered to be a stable release.  It has not been extensively tested and may have significant unknown bugs.  This is being made available so that users can test the new release and report problems and make suggestions for improvements.

Changes since 1.11.0

Much improved SCons build scripts. These improvements include:

1. A number of command line switches have been added that give users more control over the build process. See the README file for details.

2. On some systems QT was not correctly detected by the 1.11.0 scons build scripts. The new scons build scripts should correct this and it should now build on most Linux systems and possibly netBSD and freeBSD systems.

There were also some minor changes to the user interface to facilitate functionality to be added later .

I'm pleased to announce that version 1.11.2 of LPROF is now available.  LPROF is an open source application that will create ICC profiles for use with other applications such as Scribus, CinePaint, Krita, UFRAW and the development version of GIMP. This is the fifth development snap shot of the work that has been underway since LPROF became a SourceForge project.  Please see  the LPROF SourceForge web pages http://sourceforge.net/projects/lprof for details.

Changes since 1.11.1

1. LPROF now includes scons-local to ensure that all users are using a know good version of SCons.

2. Some changes have been made to the SCons scripts to make builds more reliable. The build should now run correctly on most POSIX systems. But builds on Windows and Mac OS/X have not been tested at this point. Please report both problems and successes with builds. If you have build problems on your platform please report it in the LPROF bug tracker on SourceForge.net. If you would like to report a successfull build please report it in the LPROF Open Discussion form on SourceForge.net.

3. LPROF now correctly supports IT8.7/2 images with color depths greater than 8 bits/channel and should correctly handle images with the following per channel representations:

a. 8 bit unsigned integer.
b. 16 bit signed integer.
c. 16 bit unsigned integer.
d. 32 bit signed integer.
e. 32 bit unsigned integer.
f. 32 bit floating point (float). g. 64 bit floating point (double).

Only a and c have been tested at this point and users with the ability to create other file formats are encouraged to test these and report both problems and successes. If you find an image format that does not work please report it in the LPROF bug tracker on SourceForge.net. If you would like to report a success please report it in the LPROF Open Discussion form on SourceForge.net.

4. To implement #3 LPROF is now dependant on VIGRA. Any version from 1.30 on should work. Both 1.3.3 and 1.4.0 have been tested.
