ImageMagick provides several ways to distort an image by applying various transformations against user-supplied arguments. In Wand, the method distort() is used, and follows a basic function.
Syntax :
wand.image.distort(method, arguments, best_fit)
Parameters :
| Parameter | Input Type | Description |
|---|---|---|
| method | basestring | Black point, as a percentage of the system’s quantum range. Defaults to 0.. |
| arguments | collections.abc.Sequence | Distortion method name from DISTORTION_METHODS. |
| best_fit | bool | Attempt to resize resulting image fit distortion. Defaults False. |
Following are the Distortion Methods :
| Distortion Method | Description |
|---|---|
| ‘undefined’ | default Distortion Method |
| ‘affine’ | parallel type of distortion. |
| ‘affine_projection’ | kind of 3 parallelogram projection. |
| ‘scale_rotate_translate’ | transformation distortion |
| ‘perspective’ | 3 dimensional outwards projection distortion. |
| ‘perspective_projection’ | creates a away perspective. |
| ‘bilinear_forward’ | based on bilinear equation. |
| ‘bilinear_reverse’ | based on reverse bilinear equation. |
| ‘polynomial’ | based on polynomial. |
| ‘arc’ | creates a circular curve of image. |
| ‘polar’ | creates a polar distortion effect. |
| ‘depolar’ | creates a depolar distortion effect. |
| ‘cylinder_2_plane’ | creates a cylinder to plane distortion effect. |
| ‘plane_2_cylinder’ | creates a plane to cylinder distortion effect. |
| ‘barrel’ | creates outwards bump on 2d image. |
| ‘barrel_inverse’ | creates inwards bump on 2d image. |
| ‘resize’ | resize distortion image. |
| ‘sentinel’ | creates sentinel image distortion. |

Code Example 1:
Python3
# Import Image from wand.image modulefrom wand.image import Image# Read image using Image functionwith Image(filename ="gog.png") as img: img.distort('arc', (45, )) img.save(filename ='gogdistort1.png') |

Code Example 2:
Changing DISTORTION_METHOD to ‘perspective’.
Python3
# Import Image from wand.image modulefrom wand.image import Image# Read image using Image functionwith Image(filename ="gog.png") as img: arguments = (0, 0, 20, 60, 90, 0, 70, 63, 0, 90, 5, 83, 90, 90, 85, 88) img.distort('perspective', arguments) img.save(filename ='gogdistort.png') |
