Pgmagick edge() method – Python Last Updated : 26 May, 2020 Improve Improve Like Article Like Save Share Report The edge() function is an inbuilt function in the Pgmagick library which is used to apply a convolution filter to detect edges. Syntax: edge(radius) Parameters: This function accepts single parameter as mentioned above and defined below: radius: This parameter stores the aperture of detection filter. 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 despeckle() function img.edge(0.7) # 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 despeckle() function im.edge(0.4) # invoke write function along with filename im.write('1_b.png') Output: Like Article Suggest improvement Previous Pgmagick wave() method - Python Next Pgmagick write() method - Python Share your thoughts in the comments Add Your Comment Please Login to comment...
