I need to compare 2 same-size, nearly identical images for exact differences in the RGBs of every pixel.
I would like to find a tool that already does it… seems nowhere to be found on google, strangely.
If I could even find a tool to print out the RGB values of every pixel I could compute it by hand (the images are small enough) or load that input for my tool. Again, couldn’t find anything.
Otherwise I look for a simple C library to decode GIFs and access each pixel… recommendations? I see quite a few on google, most look old and have no documentation.
I hope someone with more exposure to image processing can help me solve this this somewhat trivial task in one way or another without spending too many hours!!
If you have ImageMagick installed, it already does it.
