Member	Description
Animated	Animated geometry. The control will draw the geometry using the same stroke as in fixed in addition to a storyboard animation that will change the dash of the stroke to create a moving rubber band effect.
Fixed	Fixed geometry. The control will draw the geometry outline using a fixed stroke of thickness equals to 1.
None	No frame. The control will not draw the geometry.

The ImageViewer.Geometry property can be used to put any shape on top of this control and frame it to indicate the current region of interest area.

The coordinates of the ImageViewer.Geometry must be in image coordinates, and accordingly, the geometry will be zoomed in and out and scrolled depending on current viewer zoom value and scroll position.

The ImageViewer control does not create a geometry object by itself, however you can set the value of ImageViewer.Geometry to any System.Windows.Media.Geometry object or one of its derived classes (for example, a System.Windows.Media.PathGeometry) to simulate a region of interest. How the coordinates are calculated and what to do with this area is up to you since WPF/Silverlight System.Windows.Media.ImageSource and its derived classes do not use a region of interest.

The RasterImageViewer control is used to view a LEADTOOLS Leadtools.RasterImage object. This object has support for a region of interest that can be used to limit image processing effects to a certain area of the image of example. The Leadtools.RasterImage region is expressed with a Leadtools.RasterRegion object and you can use the RasterRegionConverter.ConvertToGeometry to convert the Leadtools.RasterRegion object to a WPF/Silverlight System.Windows.Media.Geometry object. When the region inside the Leadtools.RasterImage object being used with this RasterImageViewer is changed, the control will automatically creates a new System.Windows.Media.Geometry object and set in the ImageViewer.Geometry property.

In either cases, to draw the geometry of the viewer, you must set the value of the ImageViewer.GeometryFrameType property to GeometryFrameType.Fixed or GeometryFrameType.Animated. This value is set to GeometryFrameType.None by default which instructs the control to not draw the geometry.

For XAML example, refer to ImageViewer.GeometryFrameType.

For C#/VB examples, refer to ImageViewer.GeometryFrameType.
