Python PIL | putalpha() Method

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.putalpha() Adds or replaces the alpha layer in this image. If the image does not have an alpha layer, it’s converted to “LA” or “RGBA”. The new layer must be either “L” or “1”.

Syntax: Image.putalpha(alpha)



Parameters:
alpha – The new alpha layer. This can either be an “L” or “1” image having the same size as this image, or an integer or other color value.
