Function Documentation

void imProcessQuantizeRGBUniform	(	const imImage *	src_image,
		imImage *	dst_image,
		int	do_dither
	)

Converts a RGB image to a MAP image using uniform quantization.
with an optional 8x8 ordered dither. The RGB image must have data type IM_BYTE.

im.ProcessQuantizeRGBUniform(src_image: imImage, dst_image: imImage, do_dither: boolean) [in Lua 5] 

im.ProcessQuantizeRGBUniformNew(src_image: imImage, do_dither: boolean) -> new_image: imImage [in Lua 5] 

void imProcessQuantizeRGBMedianCut	(	const imImage *	image,
		imImage *	NewImage
	)

Converts a RGB image to a MAP image using median cut quantization.
The RGB image must have data type IM_BYTE.

im.ProcessQuantizeRGBMedianCut(src_image: imImage, dst_image: imImage) [in Lua 5] 

im.ProcessQuantizeRGBMedianCutNew(src_image: imImage) -> new_image: imImage [in Lua 5] 

void imProcessQuantizeGrayUniform	(	const imImage *	src_image,
		imImage *	dst_image,
		int	grays
	)

Quantizes a gray scale image in less that 256 grays using uniform quantization.
Both images should be IM_BYTE/IM_GRAY, the target can be IM_MAP. Can be done in-place.
The result is in the 0-255 range, except when target is IM_MAP that is in the 0-(grays-1) range.

im.ProcessQuantizeGrayUniform(src_image: imImage, dst_image: imImage, grays: number) [in Lua 5] 

im.ProcessQuantizeGrayUniformNew(src_image: imImage, grays: number) -> new_image: imImage [in Lua 5] 

void imProcessQuantizeGrayMedianCut	(	imImage *	src_image,
		imImage *	dst_image,
		int	grays
	)

Quantizes a gray scale image in less that 256 grays using median cut quantization.
Both images should be IM_BYTE/IM_GRAY. Can be done in-place.

im.ProcessQuantizeGrayMedianCut(src_image: imImage, dst_image: imImage, grays: number) [in Lua 5]
