+# How to: Transform a Brush
+This example shows how to transform <xref:System.Windows.Media.Brush> objects by using their two transformation properties: <xref:System.Windows.Media.Brush.RelativeTransform%2A> and <xref:System.Windows.Media.Brush.Transform%2A>.  
+  
+ The following examples use a <xref:System.Windows.Media.RotateTransform> to rotate the content of an <xref:System.Windows.Media.ImageBrush> by 45 degrees.  
+  
+ The following illustration shows the <xref:System.Windows.Media.ImageBrush> without a <xref:System.Windows.Media.RotateTransform>, with the <xref:System.Windows.Media.RotateTransform> applied to the <xref:System.Windows.Media.Brush.RelativeTransform%2A> property, and with the <xref:System.Windows.Media.RotateTransform> applied to the <xref:System.Windows.Media.Brush.Transform%2A> property.

+  
+## Example  
+ The first example applies a <xref:System.Windows.Media.RotateTransform> to the <xref:System.Windows.Media.Brush.RelativeTransform%2A> property of an <xref:System.Windows.Media.ImageBrush>. The <xref:System.Windows.Media.RotateTransform.CenterX%2A> and <xref:System.Windows.Media.RotateTransform.CenterY%2A> properties of a <xref:System.Windows.Media.RotateTransform> object are both set to 0.5, which is the relative coordinate of the center point of this content. As a result, the <xref:System.Windows.Media.ImageBrush> content rotates about its center.

+ [!code-xaml[BrushesIntroduction_snip#ImageBrushRelativeTransformExample](~/samples/snippets/xaml/VS_Snippets_Wpf/BrushesIntroduction_snip/XAML/BrushTransformExample.xaml#imagebrushrelativetransformexample)]  
+  
+ The second example also applies a <xref:System.Windows.Media.RotateTransform> to an <xref:System.Windows.Media.ImageBrush>; however, this example uses the <xref:System.Windows.Media.Brush.Transform%2A> property instead of the <xref:System.Windows.Media.Brush.RelativeTransform%2A> property.  
+  
+ To rotate the brush about its center, the example sets the <xref:System.Windows.Media.RotateTransform.CenterX%2A> and <xref:System.Windows.Media.RotateTransform.CenterY%2A> properties of the <xref:System.Windows.Media.RotateTransform> object to absolute coordinates. Because the brush paints a rectangle that is 175 by 90 pixels, the center point of the rectangle is (87.5, 45).
