◆ open()

bool ossimQbTileFilesHandler::open ( )

virtual

Opens the image file given entry index.

Returns: Returns true on success, false on error.

Note: This method relies on the data member ossimImageData::theImageFile being set.

This class does not support multiple entries.

Parameters

imageFile	File to open.
entryIndex

Returns: false if entry index other than 0 specified.

Implements ossimTiledImageHandler.
