Using Presets

Once you find a preset name, use it with show or create:

palettize show viridis
palettize create viridis -f gdal -o viridis.txt

Presets come from multiple sources:

• Built-in custom presets: Prefixed with custom/ (e.g., custom/grayscale)
• cmap library presets: Standard scientific colormaps like viridis, magma, inferno, plasma, etc.
