void
gimp_tile_ref (GimpTile *tile);
gimp_tile_ref is deprecated and should not be used in newly-written code.
void
gimp_tile_ref_zero (GimpTile *tile);
gimp_tile_ref_zero is deprecated and should not be used in newly-written code.
void gimp_tile_unref (GimpTile *tile,gboolean dirty);
gimp_tile_unref is deprecated and should not be used in newly-written code.
void
gimp_tile_flush (GimpTile *tile);
gimp_tile_flush is deprecated and should not be used in newly-written code.
void
gimp_tile_cache_size (gulong kilobytes);
gimp_tile_cache_size is deprecated and should not be used in newly-written code.
Sets the size of the tile cache on the plug-in side. The tile cache
is used to reduce the number of tiles exchanged between the GIMP core
and the plug-in. See also gimp_tile_cache_ntiles().
void
gimp_tile_cache_ntiles (gulong ntiles);
gimp_tile_cache_ntiles is deprecated and should not be used in newly-written code.
Sets the size of the tile cache on the plug-in side. This function
is similar to gimp_tile_cache_size() but supports specifying the
number of tiles directly.
If your plug-in access pixels tile-by-tile, it doesn't need a tile cache at all. If however the plug-in accesses drawable pixel data row-by-row, it should set the tile cache large enough to hold the number of tiles per row. Double this size if your plug-in uses shadow tiles.
