Available Sampling Filters

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

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_vertical

Flip an image vertically

overlay

Overlay an image at a given coordinate (x, y)

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.

rotate180

Rotate an image 180 degrees clockwise.

rotate270

Rotate an image 270 degrees clockwise.

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
