◆ loadState()

bool ossimCcfTileSource::loadState	(	const ossimKeywordlist &	kwl,

virtual

Method to the load (recreate) the state of an object from a keyword list.

Return true if ok or false on error.

Reimplemented from ossimImageHandler.

◆ open()

bool ossimCcfTileSource::open ( )

virtual

Returns: Returns true on success, false on error.

Note: This method relies on the data member ossimImageData::theImageFile being set. Callers should do a "setFilename" prior to calling this method or use the ossimImageHandler::open that takes a file name and an entry index.
