Expand description
Geometric transformations of images. This includes rotations, translation, and general projective transformations.
Structs§
- Projection
- A 2d projective transformation, stored as a row major 3x3 matrix.
Enums§
- Interpolation
- How to handle pixels whose pre-image lies between input pixels.
Functions§
- rotate
- Rotates an image clockwise about the provided center by theta radians.
The output image has the same dimensions as the input. Output pixels
whose pre-image lies outside the input image are set to
default. - rotate90
- Rotates an image 90 degrees clockwise.
- rotate180
- Rotates an image 180 degrees clockwise.
- rotate270
- Rotates an image 270 degrees clockwise.
- rotate180_
mut - An in-place version of
rotate180(). - rotate_
about_ center - Rotates an image clockwise about its center.
The output image has the same dimensions as the input. Output pixels
whose pre-image lies outside the input image are set to
default. - rotate_
about_ center_ no_ crop - Rotates an image clockwise about its center by theta radians without cropping.
The output image has dimensions calculated to fit the entire rotated image.
Output pixels whose pre-image lies outside the input image are set to
default. - translate
- Translates the input image by t. Note that image coordinates increase from top left to bottom right. Output pixels whose pre-image are not in the input image are set to the boundary pixel in the input image nearest to their pre-image.
- warp
- Applies a projective transformation to an image.
- warp_
into - Applies a projective transformation to an image, writing to a provided output.
- warp_
into_ with - Warps an image using the provided function to define the pre-image of each output pixel, writing into a preallocated output.
- warp_
with - Warps an image using the provided function to define the pre-image of each output pixel.
