Public Property GeoKeys As Boolean

Visual Basic (Usage)	Copy Code
Dim instance As CodecsLoadOptions Dim value As Boolean   instance.GeoKeys = value   value = instance.GeoKeys

public bool GeoKeys {get; set;}

public:
property bool GeoKeys {
   bool get();
   void set (bool value);
}

Return Value

When the value of the GeoKeys property is set to true, any subsequent load operation performed by this RasterCodecs object will automatically try to load all the TIFF Geo key tags found in the file and store them in the RasterImage.GeoKeys collection of the result image.

Internally, the RasterCodecs object will call RasterCodecs.GeoKeysSupported on the image and only tries to load the geo keys if the value returned was true.

When loading more than one page from a multi-page file, only the geo keys found in the first page will be automatically loaded when the value of this property is set to true. To manually load all the geo keys in any page, use RasterCodecs.ReadGeoKeys(String,Int32).

You must set the value of the Markers property to false to enable automatically loading the geo keys. If the value of both Markers and GeoKeys is set to true, then the markers will take take precedence and no geo keys will be loaded.

Note that any load method that uses tiles, offset or resizing will not load any file metadata automatically regardless of the value of this property.
