The palette class represents a 256 color palette for 8-bit indexed color formats. Internally each palette object maintains an array of 256 32-bit integer color values packed in ARGB8888 format. Palette objects are typically used to set the surface palette with IPTCSurface.Palette. They are also used, although less frequently, to load and save surface pixels with IPTCSurface.Load and IPTCSurface.Save. And, even less frequently, they are used with the low level pixel copying and conversion routine TPTCCopy.Palette.
