Sets the value of the BitmapScalingMode attached property on a specified dependency object.
public:
static void SetBitmapScalingMode(System::Windows::DependencyObject ^ target, System::Windows::Media::BitmapScalingMode bitmapScalingMode);public static void SetBitmapScalingMode (System.Windows.DependencyObject target, System.Windows.Media.BitmapScalingMode bitmapScalingMode);static member SetBitmapScalingMode : System.Windows.DependencyObject * System.Windows.Media.BitmapScalingMode -> unitPublic Shared Sub SetBitmapScalingMode (target As DependencyObject, bitmapScalingMode As BitmapScalingMode)Parameters
- target
- DependencyObject
The UIElement or DrawingGroup descendant on which to set the value of the BitmapScalingMode property.
- bitmapScalingMode
- BitmapScalingMode
The new value to set the property to.
Exceptions
The specified target is null.
Examples
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);
' Set the bitmap scaling mode for the image to render faster.
RenderOptions.SetBitmapScalingMode(MyImage, BitmapScalingMode.LowQuality)
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.
