NAME
ppmbrighten - change an images Saturation and Value from an HSV map
SYNOPSIS
ppmbrighten [-n] [-s <+- saturation>] [-v <+- value>] <ppmfile>
DESCRIPTION
Reads a portable pixmap as input. Converts the image from RGB space to HSV space and changes the Value by <+- value> as a percentage. Likewise with the Saturation. Doubling the Value would involve ppmbrighten -v 100 to add 100 percent to the Value. The 'n' option normalizes the Value to exist between 0 and 1 (normalized).
