Function Documentation

void imConvertPacking	(	const void *	src_data,
		void *	dst_data,
		int	width,
		int	height,
		int	src_depth,
		int	dst_depth,
		int	data_type,
		int	src_is_packed
	)

Changes the packing of the data buffer. Both must have the same width, height and data_type.
It can be used to copy data even if depth=1.
Unsed in OpenGL data conversions.

void imConvertMapToRGB	(	unsigned char *	data,
		int	count,
		int	depth,
		int	packed,
		long *	palette,
		int	palette_count
	)

Changes in-place a MAP data into a RGB data. The data must have room for the RGB image.
depth can be 3 or 4. count=width*height.
Unsed in OpenGL data conversions.
