◆ createObject() [1/2]

ossimObject * ossimTiffProjectionFactory::createObject ( const ossimString & typeName ) const

virtual

Creates an object given a type name.

Implements ossimObjectFactory.

◆ createObject() [2/2]

ossimObject * ossimTiffProjectionFactory::createObject	(	const ossimKeywordlist &	kwl,
		const char *	prefix = `0`
	)		const

virtual

Creates and object given a keyword list.

Implements ossimObjectFactory.

◆ createProjection() [1/4]

ossimProjection * ossimTiffProjectionFactory::createProjection	(	const ossimFilename &	filename,

	)		const

virtual

takes a filename.

This filename can be an image file or it can also be a ossim .geom file. It could be other forms of geom files as well. The factories job will be to determine what parser to use and return a projection if successful.
