Function Documentation

RC_EXPORT int rc_crop_box_bin	(	const uint8_t *	buf,
		int	dim,
		int	width,
		int	height,
		unsigned	box[4]
	)

Compute the bounding box.

Parameters:

[in]	buf	Input pixel buffer.
	dim	Row dimension of the input buffer.
	width	Image width in pixels.
	height	Image height in pixels.
[out]	box	Bounding box of the non-zero pixels.

Returns:

One if the image is non-empty, zero otherwise.

RC_EXPORT int rc_crop_seek_bin	(	const uint8_t *	buf,
		int	dim,
		int	width,
		int	height,
		unsigned	pos[2]
	)

Find the first non-zero pixel in traversal order.

Parameters:

[in]	buf	Input pixel buffer.
	dim	Row dimension of the input buffer.
	width	Image width in pixels.
	height	Image height in pixels.
[out]	pos	Coordinate of the first non-zero pixel.

Returns:

One if a non-zero pixel was found, zero otherwise.
