  • CompressedScanLineBlock
    A Block of possibly compressed flat scan lines. Corresponds to type attribute scanlineimage.
  • CompressedTileBlock
    This Block is a tile of flat (non-deep) data. Corresponds to type attribute tiledimage.
  • TileCoordinates
    Indicates the position and resolution level of a TileBlock or DeepTileBlock.
