CzMapTile::OpenDirectInterface

Create local copy of a map tile's memory handles, so that calls to CzMapTile::GetPixel and CzMapTile::SetPixel do not need to make API calls, and thereby execute more quickly.

bool CzMapTile::OpenDirectInterface();

None.

True if successful, and false if an error occurred (consult event log for reason).

Please note that if you make changes to the tile data after calling CzMapTile::OpenDirectInterface, you need to call CzMapTile::MarkChanged, or the changes may be lost when the tile is paged to disk.
