Function Documentation

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

Binary image edge detection.

Parameters:

	src	pixel array containing image to convert
	width	image width
	height	image height
	rect	portion of the image to process
	dest	[out] pixel array containing the edge map

Returns:

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

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

Horizontal image edge detection using the Sobel operator.

Parameters:

	src	pixel array containing image to convert
	width	image width
	height	image height
	pixel_width	pixel width
	rect	portion of the image to process
	dest	[out] pixel array containing the edge map

Returns:

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

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

Vertical image edge detection using the Prewitt operator.

Parameters:

	src	pixel array containing image to convert
	width	image width
	height	image height
	pixel_width	pixel width
	rect	portion of the image to process
	dest	[out] pixel array containing the edge map

Returns:

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

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

Vertical image edge detection using the Sobel operator.

Parameters:

	src	pixel array containing image to convert
	width	image width
	height	image height
	pixel_width	pixel width
	rect	portion of the image to process
	dest	[out] pixel array containing the edge map

Returns:

0 on success, -1 otherwise.
