Public Overloads Function WriteGeoKeysAsync( _ 
   ByVal stream As ILeadStream, _ 
   ByVal pageNumber As Integer, _ 
   ByVal geoKeys() As Leadtools.RasterTagMetadata _ 
) As IAsyncAction 
public IAsyncAction WriteGeoKeysAsync(  
   ILeadStream stream, 
   int pageNumber, 
   Leadtools.RasterTagMetadata[] geoKeys 
) 
 function Leadtools.Codecs.RasterCodecs.WriteGeoKeysAsync(ILeadStream,Int32,RasterTagMetadata[])(  
   stream , 
   pageNumber , 
   geoKeys  
) 
public: 
IAsyncAction^ WriteGeoKeysAsync(  
   ILeadStream^ stream, 
   int pageNumber, 
   Leadtools.array<RasterTagMetadata^>^ geoKeys 
)

Parameters

stream
A ILeadStream that contains the file data.

pageNumber
1-based index of the page at which to write the tag.

geoKeys
An array of RasterTagMetadata GeoKey objects to identify the data in the TIFF file.

Remarks

This method writes to or changes the GeoKeys in an existing file.

This method works only with TIFF files. If you also want to write the other TIFF tags and comments, use WriteMarkers instead.

Note: Use this method carefully. LEADTOOLS will not restrict the GeoKeys that you write. If you write bad GeoKeys, the file might become corrupted. Consult the GeoTIFF specification documentation for a list of GeoKeys.

Some restrictions apply to this function if you use an IFD to indicate to which page to write the GeoKey. See the Loading and Saving Large TIFF / BigTIFF Files topic for more information.
