My personal image editing scripts.

Usage:

• hueshift.py <file> <shift>: hue-shift all of the file by shift.
• magicshift.py <file> <target> <shift>: hue-shift saturated parts of the file with hue close to target by shift.
• redify.py <file>: remove the green and blue channels of an image, invert the red channel.
• xors.py <file> <x> <y> <n>: move file by x,y pixels and xor with the original image. repeat n times.

shift arguments are always floating-point inputs between 0 and 1.
