Last Updated :
23 Aug, 2021
The wave() function is an inbuilt function in the Python Wand ImageMagick library which is used to alter an image along with a sine wave. It creates a ripple effect.
Syntax:
wave(amplitude, wave_length, method)
Parameters: This function accepts three parameters as mentioned above and defined below:
- Amplitude: This parameter stores the value of the amplitude of the sine wave.
- Wave_length: This parameter stores the value of the wavelength of the sine wave.
- method: This parameter is used to specify the value of method which takes pixel interpolation method as ‘undefined’, ‘average’, ‘average9’, ‘average16’, ‘background’, ‘bilinear’, ‘blend’, ‘catrom’, ‘integer’, ‘mesh’, ‘nearest’, ‘spline’
Return Value: This function returns the Wand ImageMagick object.

Example 1:
Python3
from wand.image import Image
with Image(filename = '../geeksforgeeks.png' ) as image:
with image.clone() as wave:
wave.wave( 12 , 15 , 'bilinear' )
wave.save(filename = 'wave1.jpg' )
|
Output:
Example 2:
Python3
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
with Drawing() as draw:
draw.stroke_color = Color( 'black' )
draw.stroke_width = 1
draw.fill_color = Color( 'white' )
draw.circle(( 200 , 200 ),
( 100 , 100 ))
draw.font = '../Helvetica.ttf'
draw.font_size = 30
with Image(width = 400 , height = 400 , background = Color( '# 45ff33' )) as pic:
draw.text( int (pic.width / 3 ), int (pic.height / 2 ), 'GeeksForGeeks !' )
draw(pic)
pic.wave( 10 , 10 , 'blend' )
pic.save(filename = 'wave2.jpg' )
