◆ open() [3/3]

bool ossimTiffTileSource::open ( )

protectedvirtual

Returns true if no errors initializing object.

Notes:

Callers of this method must ensure "theTiffPtr" data member is initialized.
This method was added to consolidate object initialization code between constructor and public open method.

Implements ossimImageHandler.
