RenderOptions::SetBitmapScalingMode Method (DependencyObject^, BitmapScalingMode)

.NET Framework (current version)

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

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

Syntax

public:
static void SetBitmapScalingMode(
	DependencyObject^ target,
	BitmapScalingMode bitmapScalingMode
)

Parameters

target: Type: System.Windows::DependencyObject^
The UIElement or DrawingGroup descendant on which to set the value of the BitmapScalingMode property.

bitmapScalingMode: Type: System.Windows.Media::BitmapScalingMode
The new value to set the property to.

Exceptions

Exception	Condition
ArgumentNullException	The specified target is null.

Remarks

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.

Examples

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