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.
