Modify the color balance of the specified drawable.
Modify the color balance of the specified drawable. There are three axis which can be modified: cyan-red, magenta-green, and yellow-blue. Negative values increase the amount of the former, positive values increase the amount of the latter. Color balance can be controlled with the 'transfer_mode' setting, which allows shadows, mid-tones, and highlights in an image to be affected differently. The 'preserve-lum' parameter, if TRUE, ensures that the luminosity of each pixel remains fixed.
