Syntax

Objective-C

C++

public void WriteGeoKeys( 
   string fileName, 
   int pageNumber, 
   RasterCollection<RasterTagMetadata> geoKeys 
)

Public Overloads Sub WriteGeoKeys( _ 
   ByVal fileName As String, _ 
   ByVal pageNumber As Integer, _ 
   ByVal geoKeys As Leadtools.RasterCollection(Of RasterTagMetadata) _ 
)

public void WriteGeoKeys(  
   string fileName, 
   int pageNumber, 
   Leadtools.RasterCollection<RasterTagMetadata> geoKeys 
)

- (BOOL)writeGeoKeys:(nullable NSArray<LTRasterTagMetadata *> *)geoKeys  
              toFile:(NSString *)file  
          pageNumber:(NSInteger)pageNumber  
               error:(NSError **)error

 function Leadtools.Codecs.RasterCodecs.WriteGeoKeys(String,Int32,RasterCollection{RasterTagMetadata})(  
   fileName , 
   pageNumber , 
   geoKeys  
)

public: 
void WriteGeoKeys(  
   String^ fileName, 
   int pageNumber, 
   Leadtools.RasterCollection<RasterTagMetadata^>^ geoKeys 
)

Parameters

fileName
A String that contains the file name.

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

geoKeys
A collection 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.

For an example, refer to EnumGeoKeys.
