Psycho Posted July 24, 2009 Share Posted July 24, 2009 I think you should look at ImageMagik which is supported with PHP. I believe it has the capability to convert an image from CMYK to RGB. Not 100% sure: http://www.imagemagick.org/script/index.php Link to comment https://forums.phpfreaks.com/topic/167228-how-to-convert-cmyk-mode-to-rgb-mod-in-php/#findComment-882263 Share on other sites More sharing options...
ignace Posted July 24, 2009 Share Posted July 24, 2009 Apparently it appears that their isn't an actual accurate algorithm to convert cmyk to rgb as pointed out by: http://developer.loftdigital.com/blog/cmyk-rgb-and-php Link to comment https://forums.phpfreaks.com/topic/167228-how-to-convert-cmyk-mode-to-rgb-mod-in-php/#findComment-882275 Share on other sites More sharing options...

The only other option would be to have a full-featured image editor installed on the server and use command line functionality to convert the images.
