Edit report at https://bugs.php.net/bug.php?id=53598&edit=1 ID: 53598 Comment by: rostavanek at gmail dot com Reported by: the-ninth at gmx dot com Summary: GD does not support color profiles Status: Assigned Type: Feature/Change Request Package: GD related Operating System: Irrelevant PHP Version: Irrelevant Assigned To: pajoye Block user comment: N Private report: N New Comment: hi i have the same exact problem using OpenCart which uses GD library... i explained everything here: http://forum.opencart.com/viewtopic.php?f=20&t=125838 essentially most APPLE MACBOOK users that use Firefox will end up with washed out colors for all images that are resized using GD library... the color profile is discarded by GD library and 'Untagged RGB' files are generated by GD library... my situation refers to OpenCart because thats where i need to fix the problem... thanks and BUMP Previous Comments: ------------------------------------------------------------------------ [2011-02-27 10:33:13] pulzarraider at gmail dot com One more example, which shows difference in image with and without color profile. Use Firefox to see the difference: Original picture (with ICC profil Samsung - Natural Color Pro) http://fotky.sme.sk/foto/171985/vrak-skeleton-coast Picture resized with GD2 library (color profile is lost, sRGB used?) http://fotky.sme.sk/foto/171985/vrak-skeleton-coast?type=v&x=650&y=433 ------------------------------------------------------------------------ [2010-12-26 19:44:26] the-ninth at gmx dot com Sorry, should be back now. I added one more: http://www.the-ninth.com/demo/demo_phpim.jpg This one was re-sized with ImageMagick, which retains the color profile.

I assume that your Firefox should display it differently, because for the one from Lightroom it knows that it is AdobeRGB while for the one from PHP/GD it will fall back to sRGB. But in any case, the essence is that color profiles are a part of images and at least some current browsers rely on this information. At the moment it is FF and Safari, and IE9 will have color-management too. Then the problem will affect the majority of users. So for the future it would be really helpful if GD would allow to read/write color profiles. Cheers, Robert ------------------------------------------------------------------------ [2010-12-23 15:52:56] pajoye@php.net I think I need more visible differences as I don't have a calibration system in place nor a calibrated monitor :P I will already analyze the delta in the meta information of both images. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
