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)
resize	Resize the supplied image to the specified dimensions `nwidth` and `nheight` are the new dimensions. `filter` is the sampling filter to use.
rotate180	Rotate an image 180 degrees clockwise.
rotate270	Rotate an image 270 degrees clockwise.
rotate90	Rotate an image 90 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 see https://en.wikipedia.org/wiki/Unsharp_masking#Digital_unsharp_masking
