Wand matte_color property in Python

Last Updated : 08 May, 2020

Some distortion transitions can not be calculated in the virtual-pixel space. Either being invalid, or NaN (not-a-number). You can define how such a pixel should be represented by setting the Image.matte_color property.

Syntax :

wand.image.matte_color = 'color'

Source Image:

Example 1:

from wand.color import Color 
# Import Image from wand.image module 
from wand.image import Image 
   
# Read image using Image function 
with Image(filename ="gog.png") as img: 
    img.matte_color = Color('BLUE') 
    img.virtual_pixel = 'tile'  
    args = (0, 0, 30, 60, 140, 0, 110, 60, 
            0, 92, 2, 90, 140, 92, 138, 90) 
    img.distort('perspective', args) 
    img.save(filename ="rdmc.jpg") 

Output :

Example 2:
changing VIRTUAL_PIXEL_METHOD to tile

from wand.color import Color 
# Import Image from wand.image module 
from wand.image import Image 
   
# Read image using Image function 
with Image(filename ="gog.png") as img: 
    arguments = (0, 0, 20, 60, 
                 90, 0, 70, 63, 
                 0, 90, 5, 83, 
                 90, 90, 85, 88) 
    img.matte_color = Color('YELLOW') 
    img.distort('perspective', arguments) 
    img.save(filename ='mattegog.png') 

Output :
