Pgmagick wave() method – Python Improve Improve Like Article Like Save Share Report The wave() function is an inbuilt function in the Pgmagick library which is used to alter an image along with a sine wave. The function returns the true value on success. Syntax: wave(amplitude, wavelength) Parameters: This function accept two parameters as mentioned above and described below: amplitude: This parameter stores the value of the amplitude of the sine wave. wavelength: This parameter stores the value of the wavelength of the sine wave. 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 wave function with amplitude 5 and wavelength 8 img.wave(5, 8) # 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 wave function with amplitude 15 and wavelength 18 im.wave(15, 18) # invoke write function along with filename im.write('1_b.png') Output: Last Updated : 26 May, 2020 Like Article Save Article Previous Pgmagick edge() method - Python Next Pgmagick edge() method - Python Share your thoughts in the comments Add Your Comment Please Login to comment...
