gimp-gradient-get-uniform-samples

Federico Mena Quintero

Description

Sample the specified in uniform parts.

Help

This procedure samples the active gradient in the specified number of uniform parts. It returns a list of floating-point values which correspond to the RGBA values for each sample. The minimum number of samples to take is 2, in which case the returned colors will correspond to the { 0.0, 1.0 } positions in the gradient. For example, if the number of samples is 3, the procedure will return the colors at positions { 0.0, 0.5, 1.0 }.
