Functions

blur	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
crop_imm	Return an immutable view into an image
filter3x3	Perform a 3x3 box filter on the supplied image. kernel is an array of the filter weights of length 9.
flip_horizontal	Flip an image horizontally
flip_horizontal_in	Flip an image horizontally and put the result into the destination ImageBuffer.
flip_horizontal_in_place	Flip an image horizontally in place.
flip_vertical	Flip an image vertically
flip_vertical_in	Flip an image vertically and put the result into the destination ImageBuffer.
flip_vertical_in_place	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	Resize the supplied image to the specified dimensions. nwidth and nheight are the new dimensions. filter is the sampling filter to use.
rotate90	Rotate an image 90 degrees clockwise.
rotate90_in	Rotate an image 90 degrees clockwise and put the result into the destination ImageBuffer.
rotate180	Rotate an image 180 degrees clockwise.
rotate180_in	Rotate an image 180 degrees clockwise and put the result into the destination ImageBuffer.
rotate180_in_place	Rotate an image 180 degrees clockwise in place.
rotate270	Rotate an image 270 degrees clockwise.
rotate270_in	Rotate an image 270 degrees clockwise and put the result into the destination ImageBuffer.
thumbnail	Resize the supplied image to the specific dimensions.
tile	Tile an image by repeating it multiple times
unsharpen	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
