Module geometric_transformations

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.
• 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.
• 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.
