-
Generate an image using only `n_colors` or less colors as close as possible to the input image:
pnmcolormap n_colors path/to/input.pnm > path/to/output.ppm
-
Use the splitspread strategy for determining the output colors, possibly producing a better result for images with small details:
pnmcolormap -splitspread n_colors path/to/input.pnm > path/to/output.ppm
-
Sort the resulting colormap, which is useful for comparing colormaps:
pnmcolormap -sort path/to/input.pnm > path/to/output.ppm
