Why are my pixels changed on some computers
I use Canvas to getImageData. On most of our client's computers retrieved pixels are same as in the original image. But, for few users some of the R,G,B components are raised or lowered by 1.
Image is PNG with only IHDR, IDATA and IEND chunks. So there is no color correction data. I must say that on these computers everything works ok on Chrome.
Images are DATA URIs, if it makes any difference.
