PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. The
Image
module provides a class with the same name which is used to represent a PIL image. The module also provides a number of factory functions, including functions to load images from files, and to create new images.
Image.convert()
Returns a converted copy of this image. For the âPâ mode, this method translates pixels through the palette. If mode is omitted, a mode is chosen so that all information in the image and the palette can be represented without a palette.
Syntax: Image.convert(mode=None, matrix=None, dither=None, palette=0, colors=256)
Parameters:
mode â The requested mode. See: Modes.
matrix â An optional conversion matrix. If given, this should be 4- or 12-tuple containing floating point values.
dither â Dithering method, used when converting from mode âRGBâ to âPâ or from âRGBâ or âLâ to â1â. Available methods are NONE or FLOYDSTEINBERG (default).
palette â Palette to use when converting from mode âRGBâ to âPâ. Available palettes are WEB or ADAPTIVE.
colors â Number of colors to use for the ADAPTIVE palette. Defaults to 256.
Returns: An Image object.
