Remarks

An ImageBrush is a type of TileBrush that defines its content as an image, which is specified by its ImageSource property. You can control how the image is stretched, aligned, and tiled, enabling you to produce patterns and other effects. The following images show some effects that can be achieved with an ImageBrush.

ImageBrush output examples
An ImageBrush can paint shapes, controls, text, and more

As mentioned, an ImageBrush paints an area with an ImageSource. The most common type of ImageSource to use with an ImageBrush is a BitmapImage, which describes a bitmap graphic. You can use a DrawingImage to paint using a Drawing object, but it is simpler to use a DrawingBrush instead. For more information about ImageSource objects, see Imaging Overview.

For more information about ImageBrush features, see Painting with Images, Drawings, and Visuals overview.

Freezable Features

Because the ImageBrush class inherits from Freezable, ImageBrush objects gain several special features, which include the following: they can be declared as , shared among multiple objects, made read-only to improve performance, cloned, and made thread safe. For more information about the features provided by Freezable objects, see Freezable Objects Overview.

Constructors
