public bool Markers { get; set; }
@property (nonatomic, assign) BOOL markers;
public boolean getMarkers()
public void setMarkers(boolean value)
Markers # get and set (CodecsLoadOptions)
Value | Description |
---|---|
true | To enable loading metadata markers if present in the file. |
false | To disable loading metadata markers in the file. The default value is false. |
When the value of the Markers property is set to true, any subsequent load operation performed by this RasterCodecs object will automatically try to load all the metadata (tags and comments) found in the file and store them in the RasterImage.Markers collection of the resulting image.
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.
