GeoKeys Property (CodecsLoadOptions)
Summary
Gets or sets a value that indicates whether any TIFF Geo key tags found in the file should be automatically loaded.
Syntax
public bool GeoKeys {get; set;} Public Property GeoKeys As Boolean public bool GeoKeys {get; set;} @property (nonatomic, assign) BOOL geoKeys public boolean getGeoKeys()public void setGeoKeys(boolean value)
get_GeoKeys();set_GeoKeys(value);Object.defineProperty('GeoKeys');
Property Value
true to automatically load any TIFF Geo key tags found in the file, otherwise; false.
Remarks
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 resulting image.
Internally, the RasterCodecs object will call GeoKeysSupported on the image and only tries to load the GeoKeys if the value returned was true.
When loading more than one page from a multi-page file, only the GeoKeys found in the first page will be automatically loaded when the value of this property is set to true. To manually load all the GeoKeys in any page, use ReadGeoKeys.
You must set the value of the Markers property to false to enable automatically loading the GeoKeys. If the value of both Markers and GeoKeys is set to true, then the markers will take take precedence and no GeoKeys 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.
Example
For an example, refer to Tags.
