gimp_curves_explicit (1995-1996)

NAME

gimp_curves_explicit - Modifies the intensity curve(s) for specified drawable.

SYNOPSIS

gimp_curves_explicit (drawable,channel,num_bytes,curve)

DESCRIPTION

Modifies the intensity mapping for one channel in the specified drawable. The drawable must be either grayscale or RGB, and the channel can be either an intensity component, or the value. The 'curve' parameter is an array of bytes which explicitly defines how each pixel value in the drawable will be modified. Use the 'gimp_curves_spline' function to modify intensity levels with Catmull Rom splines.
