DESCRIPTION

This routine over-writes an image with a gamma corected version. The second argument is a vector of three gamma values one for each channel. If it is NULL, then default gamma is used, either from lookup tables in standard placess (usually not available), or, if that fails, using standard gamma correction.

RETURNS

NO_ERROR on success, and ERROR on failure, with an appropriate error message being set.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
