Function Documentation

void imProcessPixelate (  const imImage *  src_image,
imImage *  dst_image,
int  box_size
) 
 

Generates a zoom in effect averaging colors inside a square region.
Operates only on IM_BYTE images.

im.ProcessPixelate(src_image: imImage, dst_image: imImage, box_size: number) [in Lua 5] 
im.ProcessPixelateNew(src_image: imImage, box_size: number) -> new_image: imImage [in Lua 5]

void imProcessPosterize (  const imImage *  src_image,
imImage *  dst_image,
int  level
) 
 

A simple Posterize effect. It reduces the number of colors in the image eliminating less significant bit planes. Can have 1 to 7 levels. See imProcessBitMask.
Image data type must be integer.

im.ProcessPosterize(src_image: imImage, dst_image: imImage, level: number) [in Lua 5] 
im.ProcessPosterizeNew(src_image: imImage, level: number) -> new_image: imImage [in Lua 5]
