- affine ๐Functions for performing affine transformations.
- Functions for altering and converting the color of pixelbufs
- sample ๐Functions and filters for the sampling of pixels.
Enumsยง
- Available Sampling Filters.
Functionsยง
- Image sampling Performs a Gaussian blur on the supplied image.
sigma
is a measure of how much to blur by. - Return a mutable view into an image The coordinates set the position of the top left corner of the crop.
- crop_
dimms ๐ - Return an immutable view into an image The coordinates set the position of the top left corner of the crop.
- Image sampling Perform a 3x3 box filter on the supplied image.
kernel
is an array of the filter weights of length 9. - Affine transformations Flip an image horizontally
- Affine transformations Flip an image horizontally and put the result into the destination
ImageBuffer
. - Affine transformations Flip an image horizontally in place.
- Affine transformations Flip an image vertically
- Affine transformations Flip an image vertically and put the result into the destination
ImageBuffer
. - Affine transformations Flip an image vertically in place.
- Fill the image with a linear horizontal gradient
- Image sampling Linearly sample from an image using coordinates in [0, w-1] and [0, h-1].
- Image sampling Sample from an image using coordinates in [0, w-1] and [0, h-1], taking the nearest pixel.
- Overlay an image at a given coordinate (x, y)
- Calculate the region that can be copied from top to bottom.
- overlay_
bounds_ ๐ext Calculate the region that can be copied from top to bottom. - Replace the contents of an image at a given coordinate (x, y)
- Image sampling Resize the supplied image to the specified dimensions.
nwidth
andnheight
are the new dimensions.filter
is the sampling filter to use. - Affine transformations Rotate an image 90 degrees clockwise.
- Affine transformations Rotate an image 90 degrees clockwise and put the result into the destination

- Affine transformations Rotate an image 270 degrees clockwise.
- Affine transformations Rotate an image 180 degrees clockwise and put the result into the destination
ImageBuffer
. - Affine transformations Rotate an image 180 degrees clockwise in place.
- Affine transformations Rotate an image 270 degrees clockwise and put the result into the destination
ImageBuffer
. - Image sampling Linearly sample from an image using coordinates in [0, 1].
- Image sampling Sample from an image using coordinates in [0, 1], taking the nearest coordinate.
- Image sampling Resize the supplied image to the specific dimensions.
- Tile an image by repeating it multiple times
- Image sampling Performs an unsharpen mask on the supplied image.
sigma
is the amount to blur the image by.threshold
is the threshold for minimal brightness change that will be sharpened. - Fill the image with a linear vertical gradient
