Wand wave() function in Python

0 0 1 minute read

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.

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")
