Pgmagick gamma() method – Python Improve Improve Like Article Like Save Share Report The gamma() function is an inbuilt function in the Pgmagick library which is used to level of gamma correction. The function returns the true value on success. Syntax: gamma(red, green, blue) Parameters: This function accepts three parameters as red, green and blue which correct the gamma level of red, green and blue color respectively. Return Value: This function returns the Pgmagick object with image added. Input Image: Example 1: from pgmagick import Image, DrawableCircle, DrawableText from pgmagick import Geometry, Color # draw the image of dimension 600 * 600 img = Image('input.png') # invoke gamma() function img.gamma(1, 3.4, 6) # invoke write function along with filename img.write('2_a.png') Output: Example 2: # 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 gamma() function im.gamma(3, 45, 10) # invoke write function along with filename im.write('1_b.png') Output: Last Updated : 03 Jun, 2020 Like Article Save Article Previous Pgmagick edge() method - Python Next random.expovariate() function in Python Share your thoughts in the comments Add Your Comment Please Login to comment...
