====== CzMapTile::OpenDirectInterface ======

===== Description =====

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

===== Return value =====

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

===== Comments =====

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