public:
RasterCollection<RasterTagMetadata^>^ ReadGeoKeys( 
   String^ fileName,
   int pageNumber
) 

Parameters

fileName

A String containing the input file name.

pageNumber

1-based index of the page from which to read the GeoKey tags.

Return Value

To read a specific GeoKey stored in a file, use ReadGeoKey and to enumerate all the GeoKeys stored in a file use EnumGeoKeys.

This method will throw an exception if the file format does not support GeoKeys. To determine whether a file format supports GeoKeys, use GeoKeysSupported. You can also automatically load all the GeoKeys stored in a file during a load operation by setting the CodecsLoadOptions.GeoKeys property to true. The GeoKeys data will be stored in the resulting image RasterImage.GeoKeys collection.

To load all the GeoKeys stored in a stream containing the image data, use ReadGeoKeys.
