Specifies a range of tile mappings to use with the UpdateTileMappings function.

Syntax


enum D3DWDDM1_3DDI_TILE_RANGE_FLAG {  D3DWDDM_1_3DDI_TILE_RANGE_NULL               = 0x00000001, 
  D3DWDDM_1_3DDI_TILE_RANGE_SKIP               = 0x00000002, 
  D3DWDDM_1_3DDI_TILE_RANGE_REUSE_SINGLE_TILE  = 0x00000004 

};

Constants

D3DWDDM_1_3DDI_TILE_RANGE_NULL

The tile range is NULL.

If this flag is set in the UpdateTileMappings function's pRangeFlags parameter, the pRangeTileCounts parameter specifies the total number of tiles in all the tile regions, and the pTilePoolStartOffsets parameter is ignored.

D3DWDDM_1_3DDI_TILE_RANGE_SKIP

Tiles should be skipped over, and existing tile mappings should be left unchanged.

If this flag is set in the UpdateTileMappings function's pRangeFlags parameter, the pRangeTileCounts parameter specifies how many tiles from the tile regions to skip over, and the pTilePoolStartOffsets parameter is ignored.

D3DWDDM_1_3DDI_TILE_RANGE_REUSE_SINGLE_TILE

A single tile in the tile pool should be reused.

If this flag is set in the UpdateTileMappings function's pRangeFlags parameter, the pTilePoolStartOffsets parameter specifies the single tile in the tile pool to map to, and the pRangeTileCounts parameter specifies how many tiles from the tile region to map to that tile pool location.
