Wand affine_projection distortion method in Python
Last Updated :
16 Mar, 2023
Affine Projection is very much similar to scale_rotate_translate distortion type. The only difference is that it exactly needs six real numbers for the distortion arguments.
Scalex, Rotatex, Rotatey, Scaley, Translatex, Translatey
Source Image: Example #1:
Python3
from collections import namedtuple
from wand.color import Color
from wand.image import Image
Point = namedtuple( 'Point' , [ 'x' , 'y' ])
with Image(filename = 'gog.png' ) as img:
img.background_color = Color( 'skyblue' )
img.virtual_pixel = 'background'
rotate = Point( 0.1 , 0 )
scale = Point( 0.7 , 0.6 )
translate = Point( 5 , 5 )
args = (
scale.x, rotate.x, rotate.y,
scale.y, translate.x, translate.y
)
img.distort( 'affine_projection' , args)
img.save(filename = "affinegfg.png")
|
Output : Example #2: changing argument values.
Python3
from wand.color import Color
from wand.image import Image
with Image(filename = 'gog.png' ) as img:
img.background_color = Color( 'skyblue' )
img.virtual_pixel = 'background'
rotate = Point( 0.1 , 0.3 )
scale = Point( 0.9 , 0.2 )
translate = Point( 7 , 5 )
args = (
scale.x, rotate.x, rotate.y,
scale.y, translate.x, translate.y
)
img.distort( 'affine_projection' , args)
img.save(filename = "affinegfg2.png")
