Functions

blur	Performs a Gaussian blur on the supplied image. sigma is a measure of how much to blur by.
brighten	Brighten the supplied image. value is the amount to brighten each pixel by. Negative values decrease the brightness and positive values increase it.
contrast	Adjust the contrast of the supplied image. contrast is the amount to adjust the contrast by. Negative values decrease the contrast and positive values increase the contrast.
crop	Return a mutable view into an image
dither	Reduces the colors of the image using the supplied color_map while applying Floyd-Steinberg dithering to improve the visual conception
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
grayscale	Convert the supplied image to grayscale
index_colors	Reduces the colors using the supplied color_map and returns an image of the indices
invert	Invert each pixel within the supplied image. This function operates in place.
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.
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
