Hi, Ok, I have added some of the modifications from Arnaud to the source, and an updated tifficc and jpegicc is now available on site:
http://www.littlecms.com/tifficc.exe http://www.littlecms.com/jpegicc.exe Both are using the incoming 1.14 sources, so, it would be a chance to check new functionality. Improved areas are gamut checking, more built-in profiles and ability to save (grab) embedded profiles from images. The CMYK issue on jpeg is a known glitch from Adobe. I'm not sure if this is true or not, but as urban legend may be funny: In early versions of Photoshop, Adobe hired a junior programmer to code some parts of file formats. Internal Photoshop representation of inks is reversed, so 100% of ink is encoded as 0 and 0% is encoded as 255. This is sometimes known as "vanilla" flavor, as opposed to "chocolate", which would be to represent 100% of ink as 255. Photoshop does use chocolate flavor for RGB and vanilla flavor for inks. So the junior programmer was unaware of the translation and simply dumped the internal representation to the file. This worked for RGB but not for CMYK. Then, for compatibility sake, latter revisions of Photoshop keeps using same convention. In past, I solved it by adding two patched files for ijg library, but since it has been a source of problems, now jpegicc handles the reversing by its own, so ijg code has not to be modified anymore. Regarding CVS, well, I did set up CVS a couple of days ago, and will try to update the files to reflect current development sources, but still is a work in progress. So, please, don't take it too seriously as it is not fully synchronized. Hopefully a working beta of 1.14 would be available next week. And then I will try to get CVS operative.

I modify the source jpegicc.cc and now it is OK. I request it to marti maria but see it is not on the cvs for the moment. You can get my source file on: http://home.tele2.fr/janc Thanks NB: For debug I check result image on gqview so it is not Photoshop which is wrong but jpegicc. ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
