Pgmagick wave() method – Python
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') |
