WpfRasterSource¶

Namespace: ThinkGeo.UI.Wpf

This class allows you to view standard image types such as BMP, JPG, and PNG, using wpf classes such as BitmapSource

public class WpfRasterSource : ThinkGeo.Core.RasterSource

Inheritance Object → RasterSource → WpfRasterSource

Remarks:

This class handles all default supported image types of Windows. Any image can be opened by ImageView on Windows can also be opened by this class. As none of these types embed geographic information in them, you will need to ensure that the image file is always accompanied by a world file. The world file is text file that stores the associated geographic information we need to properly display the image along with your other feature data.
