Wand wave() function in Python

wave() function creates a wave like structure from top and bottom of the image. Creates a ripple effect within the image. We can change wavelength as well as amplitude of the image using amplitude & wave_length parameters in wave() function.

Syntax :

wand.image.wave(amplitude, wave_length)

Parameters :

Parameter	Input Type	Description
amplitude	numbers.Integer	Sets amplitude of wave.
wavelength	numbers.Integer	Sets wavelength of wave.

Example 1:

Python3

# Import Image from wand.image module
from wand.image import Image

# Read image using Image function
with Image(filename ="koala.jpeg") as img:

    # rippled effect in image using wave() function
    img.wave(amplitude = img.height / 32,
             wave_length = img.width / 4)
    img.save(filename ="wkoala2.jpeg")

Output :

Example 2: Increasing amplitude and decreasing wavelength. 

Python3

# Import Image from wand.image module
from wand.image import Image

# Read image using Image function
with Image(filename ="koala.jpeg") as img:

    # rippled effect in image using wave() function
    img.wave(amplitude = img.height / 24,
             wave_length = img.width / 8)
    img.save(filename ="wkoala2.jpeg")

Output:
