WriteGeoKeyAsync Method

public IAsyncAction WriteGeoKeyAsync( 
   ILeadStream stream,
   int pageNumber,
   RasterTagMetadata geoKey
)

'Declaration
 
Public Function WriteGeoKeyAsync( _
   ByVal stream As ILeadStream, _
   ByVal pageNumber As Integer, _
   ByVal geoKey As RasterTagMetadata _
) As IAsyncAction

'Usage
 
Dim instance As RasterCodecs
Dim stream As ILeadStream
Dim pageNumber As Integer
Dim geoKey As RasterTagMetadata
Dim value As IAsyncAction
 
value = instance.WriteGeoKeyAsync(stream, pageNumber, geoKey)

public IAsyncAction WriteGeoKeyAsync( 
   ILeadStream stream,
   int pageNumber,
   RasterTagMetadata geoKey
)

 function Leadtools.Codecs.RasterCodecs.WriteGeoKeyAsync( 
   stream ,
   pageNumber ,
   geoKey 
)

public:
IAsyncAction^ WriteGeoKeyAsync( 
   ILeadStream^ stream,
   int pageNumber,
   RasterTagMetadata^ geoKey
) 

Parameters

stream

A Leadtools.ILeadStream that contains the file data.

pageNumber

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

geoKey

GeoKey to identify the data in the Geo TIFF file.

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 Files topic for more information.
