Module imageproc::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.
