Modules

• colorops
  Functions for altering and converting the color of pixelbufs

Enums

• FilterType
  Available Sampling Filters.

Functions

• blur
  Image sampling Performs a Gaussian blur on the supplied image. sigma is a measure of how much to blur by.
• crop
  Return a mutable view into an image The coordinates set the position of the top left corner of the crop.
• crop_imm
  Return an immutable view into an image The coordinates set the position of the top left corner of the crop.
• filter3x3
  Image sampling Perform a 3x3 box filter on the supplied image. kernel is an array of the filter weights of length 9.
• flip_horizontal
  Affine transformations Flip an image horizontally
• flip_horizontal_in
  Affine transformations Flip an image horizontally and put the result into the destination ImageBuffer.
• flip_horizontal_in_place
  Affine transformations Flip an image horizontally in place.
• flip_vertical
  Affine transformations Flip an image vertically
• flip_vertical_in
  Affine transformations Flip an image vertically and put the result into the destination ImageBuffer.
• flip_vertical_in_place
  Affine transformations Flip an image vertically in place.
• horizontal_gradient
  Fill the image with a linear horizontal gradient
• overlay
  Overlay an image at a given coordinate (x, y)
• overlay_bounds
  Calculate the region that can be copied from top to bottom.
• replace
  Replace the contents of an image at a given coordinate (x, y)
• resize
  Image sampling Resize the supplied image to the specified dimensions. nwidth and nheight are the new dimensions. filter is the sampling filter to use.
• rotate90
  Affine transformations Rotate an image 90 degrees clockwise.
• rotate90_in
  Affine transformations Rotate an image 90 degrees clockwise and put the result into the destination ImageBuffer.
• rotate180
  Affine transformations Rotate an image 180 degrees clockwise.
• rotate270
  Affine transformations Rotate an image 270 degrees clockwise.
• rotate180_in
  Affine transformations Rotate an image 180 degrees clockwise and put the result into the destination ImageBuffer.
• rotate180_in_place
  Affine transformations Rotate an image 180 degrees clockwise in place.
• rotate270_in
  Affine transformations Rotate an image 270 degrees clockwise and put the result into the destination ImageBuffer.
• thumbnail
  Image sampling Resize the supplied image to the specific dimensions.
• tile
  Tile an image by repeating it multiple times
• unsharpen
  Image sampling Performs an unsharpen mask on the supplied image. sigma is the amount to blur the image by. threshold is the threshold for the difference between
• vertical_gradient
  Fill the image with a linear vertical gradient
