GIMP gradient to GLSL converter

ggr2glsl

ggr2glsl is a simple utility to convert GIMP gradient files to GLSL functions.

Usage

ggr2glsl reads from standard input and writes to standard output.

To convert a gradient called purples.ggr to a glsl function, with the file name myGradient.glsl, do:

./ggr2glsl < purples.ggr > myGradient.glsl

The file myGradient.glsl now contains, among some other functions, ggr2glsl_color.

This function takes a floating point value and returns a vec4, the color in the gradient.
