ImageDrawing Class

Draws an image within a region defined by a Rect.

Namespace:  System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)

public sealed class ImageDrawing : Drawing
<ImageDrawing .../>

Performance Note: A DrawingImage provides less features then an Image for rendering images, however, DrawingImage provides performance benefits making them ideal for describing backgrounds, clip art, and for low-level drawing with Visual objects. See Drawing Objects Overview for more information.

An ImageDrawing is a type of Freezable object and therefore can be frozen to improve performance. For information about Freezable features, such as freezing and cloning, see the Freezable Objects Overview.

This example shows how to use an ImageDrawing to draw an image. An ImageDrawing enables you display an ImageSource with a DrawingBrush, DrawingImage, or Visual. To draw an image, you create an ImageDrawing and set its ImageDrawing.ImageSource and ImageDrawing.Rect properties. The ImageDrawing.ImageSource property specifies the image to draw, and the ImageDrawing.Rect property specifies the position and size of each image.

The following example creates a composite drawing using four ImageDrawing objects. This example produces the following image:
