SetBitmapScalingMode Method

RenderOptions.SetBitmapScalingMode Method (DependencyObject, BitmapScalingMode)


Sets the value of the BitmapScalingMode attached property on a specified dependency object.

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

public static void SetBitmapScalingMode(
	DependencyObject target,
	BitmapScalingMode bitmapScalingMode


Type: System.Windows.DependencyObject

The UIElement or DrawingGroup descendant on which to set the value of the BitmapScalingMode property.

Type: System.Windows.Media.BitmapScalingMode

The new value to set the property to.

Exception Condition

The specified target is null.

Use the SetBitmapScalingMode method on a UIElement or DrawingGroup descendant that is animating a bitmap.

When animating the scale of any bitmap, the default high-quality image re-sampling algorithm can sometimes consume sufficient system resources to cause frame rate degradation, effectively causing animations to stutter. By setting the BitmapScalingMode property of the RenderOptions object to LowQuality, you can create a smoother animation when scaling a bitmap.

The following example shows how to set the BitmapScalingMode for an Image object.

// Set the bitmap scaling mode for the image to render faster.
RenderOptions.SetBitmapScalingMode(MyImage, BitmapScalingMode.LowQuality);
