int rapp_scatter_u8	(	uint8_t *restrict	dst,
		int	dst_dim,
		const uint8_t *restrict	map,
		int	map_dim,
		const uint8_t *restrict	pack,
		int	width,
		int	height
	)

Scatter 8-bit pixels designated by a binary mask.

Parameters:

[out]	dst	Destination pixel buffer.
	dst_dim	Row dimension of the destination buffer.
[in]	map	Map pixel buffer.
	map_dim	Row dimension of the map buffer.
[in]	pack	Packed pixel buffer.
	width	Image width in pixels.
	height	Image height in pixels.

Returns:

The number of pixels scattered, or a negative error code on error.
