lprof-anounce Mailing List for LProf open source ICC profiler

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I have now added an lprof-users email list.  This list intended for users of 
LProf to communicate with other users to ask questions and share information 
about how to use LProf.

I'm pleased to announce that development snapshot version 1.11.3 of LPROF is 
now available.  This is the sixth development snapshot of the work that has 
been underway since LPROF became a SourceForge project.  Please see  the 
LPROF SourceForge home page at http://lprof.sourceforge.net/ 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 
snapshot appears to be stable it is a development release and as such it 
should not be considered 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.

Significant changes since the last development snapshot  include:

1. LPROF now uses the ArgyllCMS spline regression code for creating camera and 
scanner profiles.  Profiles created with the new regression code have both 
lower delta E numbers and smoother CLUT curves.  Users have control of two 
parameters used by the regression algorithm to tune the resulting profiles.  
I would like to thank Gerhard Fuernkranz for integrating this into LPROF.

2. LPROF now uses the QT QSetting API to manage user and application settings.  
On Windows systems settings are now stored in the registry.  On Mac OS/X 
QSettings uses the Carbon preferences API and on Unix/Linux/BSD systems the 
settings are stored in a text file in the $HOME/.lprof/config directory.  
Users who have been using previous 1.11.x snapshots will loose whatever 
settings had been stored in the old configuration file.   As a result users 
will need to reinstall target reference files in LPROF.

3. LPROF now has expanded the the number of items that are actively tracked in 
the settings/configuration system to include configuration details of all 
profiles created in LPROF.  This will allow users to open a profile that was 
created with LPROF and all settings in affect at the time the profile was 
created will automatically become the current settings in LPROF.  This 
includes opening IT8.7 image files and the placing of corner marks on the 
IT8.7 image.

4. The charts for setting monitor gamma in the rough monitor profiler now work 
correctly on both little endian and big endian hardware.  I would like to 
thank Oleksandr (Alex) Moskalenko for his assistance in getting the fixes 
tested for big endian hardware.

5. LPROF now uses VIGRA for all image file IO and has eliminated the need for 
TiffIO to handle tiff files.  LPROF now supports the following image file 
formats:

"BMP" - Microsoft Windows bitmap image file.
"GIF" - CompuServe graphics interchange format; 8-bit color. 
"JPEG" - Joint Photographic Experts Group JFIF format; compressed 24-bit color 
(only available if libjpeg is installed). 
"PNG" - Portable Network Graphic (only available if libpng is installed). 
"PNM" - Portable anymap. 
"PPM" - Portable pixmap format (color). 
"SUN" - SUN Rasterfile. 
"TIFF" - Tagged Image File Format. (only available if libtiff is installed.) 
"VIFF" - Khoros Visualization image file.

With 8, 16 or 32 bit integer or 32 or 64 bit floating point values per color 
channel if these higher bit depths are supported by the image file format.  8 
and 16 bit integer and 32 bit floating point per channel image files have 
been tested and are working correctly.  32 bit integer and 64 bit floating 
point per channel images have not been tested at this time but should work.  
If anyone has the ability to test the untested formats please let the project 
team know your results.

6. Numerous other smaller bug fixes, enhancements and documentation 
improvements.

The development team has discovered that QT version 3.3.5 has a bug that will 
prevent LPROF or any application that uses custom QT widgets from building.  
This normally results in error messages about missing header files during the 
build process.  The files incorrectly listed as missing are:

it8selector.h
it8fileselector.h
iccprofileselector.h

Please see 
http://www.trolltech.com/developer/tasktracker.html?method=entry&id=85440 for 
more details about the bug and possible fixes.  If you receive messages like 
this while building LPROF please verify your QT version before opening a bug 
report.   

Please feel free to download, build, install and test this development 
snapshot.  User feedback is very much appreciated and any reported problems 
will receive prompt attention from the LPROF development team.  In addition, 
LPROF could use your help in other ways and we are looking for volunteers to 
handle various tasks.  For example, the LPROF team would really like to have 
someone work on getting the Windows and/or Max OS/X SCons builds working 
correctly and there are many other areas where we could use additional help.   
Many of the things that need to be done are non-technical so even those that 
do not have a technical back ground can contribute.  Please contact me if you 
would like to get involved in this effort in any way.

Hi all,

  I want to redirect the STDOUT to a text widget in gtk. Actually I am
invoking some APIs which spit some messages on console. I want to

 any suggestions?

Thanks in advance

I'm pleased to announce that version 1.11.2 of LPROF is now available. =A0L=
PROF
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. =A0Pl=
ease
see =A0the LPROF SourceForge web pages http://sourceforge.net/projects/lprof
for details.

This is a development snapshot of what will become version 1.12 when it is
stable. =A0Although testing by the development team indicates that this sna=
pshot=20
appears to be stable it is a development release and as such it should
not considered to be a stable release. =A0It has not been extensively tested
and may have significant unknown bugs. =A0This is being made available so t=
hat
users can test the new release and report problems and make suggestions for
improvements.

Changes since 1.11.1

1. LPROF now includes scons-local to ensure that all users are using a know=
=20
good version of SCons.=20

2. Some changes have been made to the SCons scripts to make builds more=20
reliable.  The build should now run correctly on most POSIX systems.  But=20
builds on Windows and Mac OS/X have not been tested at this point.  Please=
=20
report both problems and successes with builds.  If you have build problems=
=20
on your platform please report it in the LPROF bug tracker on=20
SourceForge.net.  If you would like to report a successfull build please=20
report it in the LPROF Open Discussion form on SourceForge.net. =20

3. LPROF now correctly supports IT8.7/2 images with color depths greater th=
an=20
8 bits/channel and should correctly handle images with the following per=20
channel representations:
 =20
   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=20
create other file formats are encouraged to test these and report both=20
problems and successes.  If you find an image format that does not work=20
please report it in the LPROF bug tracker on SourceForge.net.  If you would=
=20
like to report a success please report it in the LPROF Open Discussion form=
=20
on SourceForge.net. =20

4. To implement #3 LPROF is now dependant on VIGRA.   Any version from 1.30=
 on=20
should work.  Both 1.3.3 and 1.4.0 have been tested.

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=20
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=
=20
scripts.  The new scons build scripts should correct this and it should now=
=20
build on most Linux systems and possibly netBSD and freeBSD systems.

There were also some minor changes to the user interface to facilitate=20
functionality to be added later .=20
