int	Rast3d_cache_size_encode (int cacheCode, int n)
	Returns a number which encodes multiplicity n of cacheCode. This value can be used to specify the size of the cache. If cacheCode is the size (in tiles) of the cache the function returns cacheCode * n. If cacheCode is RASTER3D_USE_CACHE_DEFAULT the function returns RASTER3D_USE_CACHE_DEFAULT. If cacheCode is RASTER3D_USE_CACHE_??? the function returns a value encoding RASTER3D_USE_CACHE_??? and n. Here RASTER3D_USE_CACHE_??? is one of RASTER3D_USE_CACHE_X, RASTER3D_USE_CACHE_Y, RASTER3D_USE_CACHE_Z, RASTER3D_USE_CACHE_XY, RASTER3D_USE_CACHE_XZ, RASTER3D_USE_CACHE_YZ, or RASTER3D_USE_CACHE_XYZ, where e.g. RASTER3D_USE_CACHE_X specifies that the cache should store as many tiles as there exist in one row along the x-axis of the tile cube, and RASTER3D_USE_CACHE_XY specifies that the cache should store as many tiles as there exist in one slice of the tile cube with constant Z coordinate.

Rast3d_cache_size_encode()

int Rast3d_cache_size_encode	(	int	cacheCode,
		int	n
	)

Returns a number which encodes multiplicity n of cacheCode. This value can be used to specify the size of the cache. If cacheCode is the size (in tiles) of the cache the function returns cacheCode * n. If cacheCode is RASTER3D_USE_CACHE_DEFAULT the function returns RASTER3D_USE_CACHE_DEFAULT. If cacheCode is RASTER3D_USE_CACHE_??? the function returns a value encoding RASTER3D_USE_CACHE_??? and n. Here RASTER3D_USE_CACHE_??? is one of RASTER3D_USE_CACHE_X, RASTER3D_USE_CACHE_Y, RASTER3D_USE_CACHE_Z, RASTER3D_USE_CACHE_XY, RASTER3D_USE_CACHE_XZ, RASTER3D_USE_CACHE_YZ, or RASTER3D_USE_CACHE_XYZ, where e.g. RASTER3D_USE_CACHE_X specifies that the cache should store as many tiles as there exist in one row along the x-axis of the tile cube, and RASTER3D_USE_CACHE_XY specifies that the cache should store as many tiles as there exist in one slice of the tile cube with constant Z coordinate.
