Function Documentation

int tl_normalize_gray	(	tlPixel *	src,
		int	width,
		int	height,
		tlMask *	mask,
		tlRect *	rect,
		tlPixel *	dest
	)

Normalize a GRAY picture so that it uses to full range as defined by TL_MIN_PIXEL_VAL and TL_MAX_PIXEL_VAL. The normlization is limited to the masked area.

Parameters:

	src	the pixel array to normalize
	width	image width
	height	image height
	mask	data mask
	rect	portion of the image to process
	dest	[out] destination pixel array

Returns:

0 on success, -1 otherwise.
See error management for details.

Note:

src and dest can be pointing to the same pixel array. When normalizing a subimage, the normalization occurs in the subimage ONLY (the rest of the image is ignored); therefore, the same area of an image can render differently if normalized within the whole image or a subimage.

int tl_normalize_gray	(	tlPixel *	src,
		int	width,
		int	height,
		tlRect *	rect,
		tlPixel *	dest
	)

Normalize a GRAY picture so that it uses to full range as defined by TL_MIN_PIXEL_VAL and TL_MAX_PIXEL_VAL.

Parameters:

	src	the pixel array to normalize
	width	image width
	height	image height
	rect	portion of the image to process
	dest	[out] destination pixel array

Returns:

0 on success, -1 otherwise.
