RenderOptions..::.SetBitmapScalingMode Method

Updated: February 2009

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

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

Syntax

Visual Basic (Declaration)

Public Shared Sub SetBitmapScalingMode ( _
    target As DependencyObject, _
    bitmapScalingMode As BitmapScalingMode _
)

Visual Basic (Usage)

Dim target As DependencyObject
Dim bitmapScalingMode As BitmapScalingMode

RenderOptions.SetBitmapScalingMode(target, _
    bitmapScalingMode)

public static void SetBitmapScalingMode(
    DependencyObject target,
    BitmapScalingMode bitmapScalingMode
)

Visual C++

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

JScript

public static function SetBitmapScalingMode(
    target : DependencyObject, 
    bitmapScalingMode : BitmapScalingMode
)

XAML

You cannot use methods in XAML.

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.

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.

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

Platforms

Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003

The .NET Framework and .NET Compact Framework do not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
