Pgmagick solarize() method - Python Last Updated : 19 Oct, 2021 Comments Improve Suggest changes Like Article Like Report The solarize() function is an inbuilt function in the Pgmagick library that is used to negate all pixels above the threshold level. The function returns the true value on success. Syntax: solarize(thresholdLevel) Parameters: This function accepts a single parameter thresholdlevel which is used to specify the threshold level between 0 to 100.Return Value: This function returns the Pgmagick object with image added. Input Image: Example 1: Python3 from pgmagick import Image, DrawableCircle, DrawableText from pgmagick import Geometry, Color # draw the image of dimension 600 * 600 img = Image('input.png') # invoke solarize function with factor as 60 img.solarize(60) # 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 size function with factor as 10 im.solarize(10) # invoke write function along with filename im.write('1_b.png') Output: Comment More infoAdvertise with us Next Article Pgmagick solarize() method - Python S sarthak_ishu11 Follow Improve Article Tags : Python Image-Processing Python-pgmagick Practice Tags : python Similar Reads Pgmagick resize() method - Python The resize() function is an inbuilt function in the Pgmagick library which is used to resize an image.
