Last Updated :
10 Aug, 2021
The motion_blur() function is an inbuilt function in the Python Wand ImageMagick library which is used to simulate motion blur. This function convolves the image with a Gaussian operator of the given radius and standard deviation.
Syntax:
motion_blur(radius, sigma, angle)
Parameters: This function accepts three parameters as mentioned above and defined below:
- radius: This parameter is used to store the radius of the Gaussian, in pixels.
- sigma: This parameter is used to find the standard deviation of the Gaussian, in pixels.
- angle: This parameter apply the effect along this angle.
Return Value: This function returns the Wand ImageMagick object.
Original Image:
Example 1:
Python3
from wand.image import Image
with Image(filename = '../geeksforgeeks.png' ) as image:
with image.clone() as motion_blur:
motion_blur.motion_blur( 25 , 3 , 45 )
motion_blur.save(filename = 'motion_blur1.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.motion_blur( 30 , 4 , 260 )
pic.save(filename = 'motion_blur2.jpg' )
