addProjDataPath()

void ossimHdf5ProjectionFactory::addProjDataPath ( const ossimString &  projPath )

inline

Specifies which HDF5 internal paths to search through to locate geometry information.

This can be either explicit dataset names, or group names containing known datasets, such as "Latitude" and "longitude". The plugins depending on HDF5 should register their geometry groups here in the same order as image entries.

createObject() [1/4]

ossimObject * ossimHdf5ProjectionFactory::createObject ( const ossimString &  typeName ) const

createProjection() [1/6]

ossimProjection * ossimHdf5ProjectionFactory::createProjection ( const ossimFilename &  filename, ossim_uint32  entryIdx  ) 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.
