bool ossimOpjJp2Reader::getOverviewTile	(	ossim_uint32	resLevel,

Gets an overview tile.

Overrides ossimImageHandler::getOverviewTile

Parameters

resLevel	The resolution level to pull from with resLevel 0 being full res.
result	The tile to stuff. Note The requested rectangle in full image space and bands should be set in the result tile prior to passing. This method will subtract the subImageOffset if needed for external overview call since they do not know about the sub image offset.

Returns: true on success false on error. Typically this will return false if resLevel==0 unless the overview has r0. If return is false, result is undefined so caller should handle appropriately with makeBlank or whatever.
