    11Summary of the bug:
    22When I try to zoom an image, if this image has a white background (255,255,255) I obtain an output with a variable white (between 255,255,255 and 255,254,255). It is ok with other colors.

     4IMPORTANT: this only happens with big scale number, for example scale=12800x7200. It is ok with scale=1280x720.
