HwndSourceParameters.UsesPerPixelOpacity Property

Definition

Namespace:

System.Windows.Interop

Assembly:

PresentationCore.dll

Gets a value that declares whether the per-pixel opacity of the source window content is respected.

public:
 property bool UsesPerPixelOpacity { bool get(); void set(bool value); };

public bool UsesPerPixelOpacity { get; set; }

member this.UsesPerPixelOpacity : bool with get, set

Public Property UsesPerPixelOpacity As Boolean

Property Value

Boolean

true if using per-pixel opacity; otherwise, false.

Remarks

By enabling per-pixel opacity, the system no longer draws the non-client area.

The opacity is used when the window is drawn on the desktop (it represents a final rendering step and does not appear as a contributor to property values such as Opacity).

UsesPerPixelOpacity applies only to top-level windows.
