Indicates whether or not the image is tiled internally.

This implementation returns true if (getImageTileWidth() && getImageTileHeight()) are both non zero. Override in the image handler if something else is desired. Returns true if tiled, false if not.

Reimplemented from ossimImageHandler.

◆ open()

bool ossimKakaduJpipHandler::open ( )

Pure virtual open.

Derived classes must implement.

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.
