provides convenient functions and algorithms for manipulating colors in images, with full generality for arbitrary numbers of color channels.
adjust levels, brightness, contrast, gamma, etc.

tally of levels in each channel
convert between color spaces

negate color values
reduce any image to black and white
reduce the color palette of an image
the alpha channel of the image
apply an arbitrary function to each pixel value
create pseudocolor images
