| int | Rast3d_write_tile (RASTER3D_Map *map, int tileIndex, const void *tile, int type) |
| Writes tile with index tileIndex to the file corresponding to map. It is assumed that the cells in tile are of type which must be one of FCELL_TYPE and DCELL_TYPE. The actual type used to write the tile depends on the type specified at the time when map is initialized. A tile can only be written once. Subsequent attempts to write the same tile are ignored.

| int | Rast3d_write_tile_float (RASTER3D_Map *map, int tileIndex, const void *tile) |
Is equivalent to Rast3d_write_tile (map, tileIndex, tile, FCELL_TYPE). More... | |
| int | Rast3d_write_tile_double (RASTER3D_Map *map, int tileIndex, const void *tile) |
Is equivalent to Rast3d_write_tile (map, tileIndex, tile, DCELL_TYPE). More... | |
| int | Rast3d_flush_tile (RASTER3D_Map *map, int tileIndex) |
| Writes the tile with tileIndex to the file corresponding to map and removes the tile from the cache (in non-cache mode the buffer provided by the map-structure is written). If this tile has already been written before the write request is ignored. If the tile was never referred to before the invokation of Rast3d_flush_tile, a tile filled with NULL-values is written.

| int | Rast3d_flush_tile_cube (RASTER3D_Map *map, int xMin, int yMin, int zMin, int xMax, int yMax, int zMax) |
| Writes the tiles with tile-coordinates contained in the axis-parallel cube with vertices (xMin, yMin, zMin) and (xMax, yMax, zMax). Tiles which are not stored in the cache are written as NULL-tiles. Write attempts for tiles which have already been written earlier are ignored. More... | |
| int | Rast3d_flush_tiles_in_cube (RASTER3D_Map *map, int xMin, int yMin, int zMin, int xMax, int yMax, int zMax) |
| Writes those tiles for which every cell has coordinate contained in the axis-parallel cube defined by the vertices with cell-coordinates (xMin, yMin, zMin) and (xMax, yMax, zMax). Tiles which are not stored in the cache are written as NULL-tiles. Write attempts for tiles which have already been written earlier are ignored. More... | |
