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.
Example 1:
Python3
Output:
Example 2:
Python3
Syntax:Input Image:wave(amplitude, wavelength)Parameters: This function accept two parameters as mentioned above and described below:Return Value: This function returns the Pgmagick object with image added.
- 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.
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')
# 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')
Output:
