pnmcolormap

all

Create quantization color map for a PNM image.

Options (2)

boolean

Use the splitspread strategy for determining the output colors, possibly producing a better result for images with small details

Example: pnmcolormap {{[-splits|-splitspread]}} {{n_colors}} {{path/to/input.pnm}} > {{path/to/output.ppm}}

boolean

Sort the resulting colormap, which is useful for comparing colormaps

Example: pnmcolormap {{[-so|-sort]}} {{path/to/input.pnm}} > {{path/to/output.ppm}}

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 [-splits|-splitspread] n_colors path/to/input.pnm > path/to/output.ppm

Sort the resulting colormap, which is useful for comparing colormaps

pnmcolormap [-so|-sort] path/to/input.pnm > path/to/output.ppm
