Pgmagick wave() method – Python
  • Last Updated : 26 May, 2020

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:

code

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')

# 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')
