◆ createProjection() [1/4]

virtual ossimProjection* ossimProjectionFactoryBase::createProjection	(	const ossimFilename &	filename,
		ossim_uint32	entryIdx
	)		const

pure 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.

Implemented in ossimNitfProjectionFactory, ossimMiscProjectionFactory, ossimEpsgProjectionFactory, ossimWktProjectionFactory, ossimMapProjectionFactory, ossimTiffProjectionFactory, ossimplugins::ossimPluginProjectionFactory, ossimGdalProjectionFactory, ossimNgaProjectionFactory, ossimSensorModelFactory, ossimHdf5ProjectionFactory, ossimHdf5ProjectionFactory, and ossimJpipProjectionFactory.

Referenced by createProjection().

◆ createProjection() [2/4]

virtual ossimProjection* ossimProjectionFactoryBase::createProjection ( const ossimString & name ) const

pure virtual

Take a projection type name.

Implemented in ossimNitfProjectionFactory, ossimEpsgProjectionFactory, ossimMapProjectionFactory, ossimTiffProjectionFactory, ossimWktProjectionFactory, ossimMiscProjectionFactory, ossimplugins::ossimPluginProjectionFactory, ossimGdalProjectionFactory, ossimSensorModelFactory, ossimNgaProjectionFactory, ossimHdf5ProjectionFactory, ossimHdf5ProjectionFactory, and ossimJpipProjectionFactory.

◆ createProjection() [3/4]

virtual ossimProjection* ossimProjectionFactoryBase::createProjection	(	const ossimKeywordlist &	kwl,
		const char *	prefix
	)		const

pure virtual

Take a keywordlist.

Implemented in ossimNitfProjectionFactory, ossimEpsgProjectionFactory, ossimWktProjectionFactory, ossimMapProjectionFactory, ossimTiffProjectionFactory, ossimplugins::ossimPluginProjectionFactory, ossimMiscProjectionFactory, ossimNgaProjectionFactory, ossimGdalProjectionFactory, ossimSensorModelFactory, ossimHdf5ProjectionFactory, ossimHdf5ProjectionFactory, and ossimJpipProjectionFactory.

◆ createProjection() [4/4]

ossimProjection * ossimProjectionFactoryBase::createProjection ( ossimImageHandler * handler ) const

virtual

Reimplemented in ossimNitfProjectionFactory, and ossimTiffProjectionFactory.

Definition at line 105 of file ossimProjectionFactoryBase.cpp.

References createProjection(), ossimImageHandler::getCurrentEntry(), and ossimImageHandler::getFilename().

    if(!handler) return 0;
    return createProjection(handler->getFilename(), handler->getCurrentEntry());
 }

◆ createProjectionFromGeometryFile()

ossimProjection * ossimProjectionFactoryBase::createProjectionFromGeometryFile	(	const ossimFilename &	imageFile,
		ossim_uint32	entryIdx
	)		const

protected

This method takes the filename and tries to find an external ".geom" file.

If the "entryIndx" is 0 and the "imageFile" is foo.ntf this will look for "foo.geom". If that fails it will look for foo_e0.geom.

If the "entryIndx" is 5 and the "imageFile" is foo.ntf this will look for foo_e5.geom.

Parameters

imageFile	Image file that needs a projection.
entryIdx	For image files that support multiple images this is the zero base index to that image. Images that don't support multiple indexes should just pass 0.

Returns: An ossimProjection* on success or NULL on failure.
