WriteGeoKeysAsync(ILeadStream,Int32,RasterTagMetadata[]) Method

Show in webframe







A Leadtools.ILeadStream that contains the file data.
1-based index of the page at which to write the tag.
An array of Leadtools.RasterTagMetadata GeoKey objects to identify the data in the TIFF file.
Writes or changes one or more GeoKeys to an existing stream.
Syntax

   ILeadStream stream,
   int pageNumber,
   RasterTagMetadata[] geoKeys
)
'Declaration

   ILeadStream^ stream,

Parameters

stream
A Leadtools.ILeadStream that contains the file data.
pageNumber
1-based index of the page at which to write the tag.
geoKeys
An array of Leadtools.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 Files topic for more information.

Example
For an example, refer to EnumGeoKeys(String,Int32).
