void ReduxAlphaChannel_hq2x	(	W8 *	data,
		W32	width,
		W32	height
	)

Remove fringe from scaled hq2x images.

Parameters:

[in,out]	data	Image data.
[in]	width	Width (in pixels) of image data.
[in]	height	Height (in pixels) of image image.

Returns:

Nothing.

void RGB24_adjustBrightness	(	void *	data,
		W32	size
	)

Adjust the brightness of an RGB24 image.

Parameters:
