My lcms2 plug-in now does do correct ICC profile conversions, from any RGB color space, to any RGB color space, at 8-bit integer, 16-bit integer, and 32-bit floating point. However, to get it to work, I had to modify the babl/babl/util.h file. After modifying the babl/babl/util.h file, 16-bit tiffs open correctly. As you might recall, with the default util.h file, 16-bit tiffs open with a mysterious and erroneous "gamma=2.2 correction" having been applied. This tiff issue has nothing to do with the lcms plug-in. I realize that modifying a babl file might be a controversial move on my part. But I would ask you to look at this web page before dismissing what I've done: http://ninedegreesbelow.com/temp/gimp-lcms-5.html The modified babl/babl/util.h code can be found here: http://ninedegreesbelow.com/temp/gimp-lcms-4.html Elle -- http://ninedegreesbelow.com Articles and tutorials on open source digital imaging and photography _______________________________________________ gimp-developer-list mailing list gimp-developer-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gimp-developer-list
