Hal, I give up :( I tried to locate the Win32 executable in the "Qt4-port branch of CVS" but all I can find is v1.11.4 dated June 5, 2006, which only has support for th IT8. > > LProf CVS has support for all of the ColorChecker targets as well as the > EyeOne Scanner 1.4 target, DigitaL TargeT 003 and HCT targets (and of course > all of the IT8 flavors). For low patch count targets like the ColorChecker > 24 patch target you will get the best results using a matrix type profile. > The latest version of this code is in the Qt4-port branch of CVS which will > be merged into the main line soon. You should find a generic ColorChecker 24 > patch reference file in the data/pics subdirectory of the source tree > (ColorChecker-24patch.txt). > > Hal > > > Roger Breton
