Image Manipulation Filter like white BalanceI have been trying since one week to achieve some image manipulation filters like WHITE BALANCE, EXPOSURE and SPLIT TONING (as in Photoshop) for my IOS app, but I didn’t get a standard implementation to achieve any of them.I found the shell scripts to achieve them through ImageMagickWhite Balance is achievable through changing temperature and tint of the image also. so if someone out there knows how to manipulate these tint and temperature of image, please help me out of this. Thanks.Based on my understanding of photoshop and image manipulation, to modify the “white balance” you are essentially mapping one color value in the original image to pure white, and then a uniform mapping is applied to all colors between 0 and the color you chose. The curves filter allows you to create nonuniform mappings. It took me a while of experimenting with levels and curves in Photoshop, and then writing the corresponding code, before I had an intuitive grasp of this relationship.
