ImagePalette Module

The ImagePalette module contains a class of the same name torepresent the color palette of palette mapped images.

注解

This module was never well-documented. It hasn’t changed since 2001,though, so it’s probably safe for you to read the source code and puzzleout the internals if you need to.

The ImagePalette class has several methods,but they are all marked as “experimental.” Read that as you will. The[source] link is there for a reason.

  • class PIL.ImagePalette.ImagePalette(mode='RGB', palette=None, size=0)[源代码]
  • Color palette for palette mapped images

参数:

  • mode – The mode to use for the Palette. See:模式. Defaults to “RGB”
  • palette – An optional palette. If given, it must be a bytearray,an array or a list of ints between 0-255 and of length sizetimes the number of colors in mode. The list must be alignedby channel (All R values must be contiguous in the list before Gand B values.) Defaults to 0 through 255 per channel.
  • size – An optional palette size. If given, it cannot be equal toor greater than 256. Defaults to 0.
  • getcolor(color)[源代码]
  • Given an rgb tuple, allocate palette entry.

  • getdata()[源代码]
  • Get palette contents in format suitable for the low-levelim.putpalette primitive.
