Pgmagick equalize() method - Python Last Updated : 04 Oct, 2021 Comments Improve Suggest changes Like Article Like Report The equalize() function is an inbuilt function in the Pgmagick library which is used to perform histogram equalization to the image. Syntax: equalize() Parameters: This function does not accept any parameters.Return Value: This function returns the Pgmagick object with image added. Input Image: Example 1: Python3 # import library from pgmagick import Image, DrawableCircle, DrawableText from pgmagick import Geometry, Color # draw the image of dimension 600 * 600 img = Image('input.png') # invoke equalize() function img.equalize() # invoke write function along with filename img.write('2_a.png') Output: Example 2: Python3 # import library from pgmagick import Image, DrawableCircle, DrawableText from pgmagick import Geometry, Color # Draw image of dimension 600 * 600 having background green im = Image(Geometry(600, 600), Color("# 32CD32")) # invoke DrawableCircle() function circle = DrawableCircle(100, 100, 300, 20) # invoke draw() function im.draw(circle) # set font size to 40px im.fontPointsize(40) # invoke DrawableText() function text = DrawableText(250, 450, "GeeksForGeeks") # invoke draw() function im.draw(text) # invoke equalize() function im.equalize() # invoke write function along with filename im.write('1_b.png') Output: Comment More infoAdvertise with us Next Article Pgmagick equalize() method - Python sarthak_ishu11 Follow Improve Article Tags : Python Image-Processing Python-pgmagick Practice Tags : python Similar Reads Pgmagick edge() method - Python The edge() function is an inbuilt function in the Pgmagick library which is used to apply a convolution filter to detect edges.
