The ImagePalette Module
To use the ImagePalette class and related functions, import the ImagePalette module.
Examples
Attach a Palette to an Image (Sequence Syntax)
palette = []
for i in range(256):
palette.extend((i, i, i)) # grayscale wedge
assert len(palette) == 768
im.putpalette(palette)
Attach a Palette to an Image (Not Yet Supported)
import ImagePalette
palette = ImagePalette.ImagePalette("RGB")
palette.putdata(...)
im.putpalette(palette)
Getting the Palette Contents Using Resize/Convert
assert im.mode == "P"
lut = im.resize((256, 1))
lut.putdata(range(256))
lut = lut.convert("RGB").getdata()
# lut now contains a sequence of (r, g, b) tuples
Classes

ImagePalette.ImagePalette(mode="RGB") => palette instance
This constructor creates a new palette, mapping from "P" to the given mode. The palette is initialised to a linear grayscale ramp.
