Overloads
| VirtualSurfaceImageSource(Int32, Int32) |
Initializes a new instance of the VirtualSurfaceImageSource class, specifying the size of the drawing area. |
| VirtualSurfaceImageSource(Int32, Int32, Boolean) |
Initializes a new instance of the VirtualSurfaceImageSource class, specifying the size of the drawing area and a preference for whether to render with an alpha transparency. |
VirtualSurfaceImageSource(Int32, Int32)
Initializes a new instance of the VirtualSurfaceImageSource class, specifying the size of the drawing area.
public:
VirtualSurfaceImageSource(int pixelWidth, int pixelHeight); VirtualSurfaceImageSource(int const& pixelWidth, int const& pixelHeight);public VirtualSurfaceImageSource(int pixelWidth, int pixelHeight);function VirtualSurfaceImageSource(pixelWidth, pixelHeight)Public Sub New (pixelWidth As Integer, pixelHeight As Integer)Parameters
- pixelWidth
-
Int32
int
Width of the drawing area in pixels.
- pixelHeight
-
Int32
int
Height of the drawing area in pixels.
Remarks
Windows 8 behavior
Windows 8 validates that pixelWidth and pixelHeight are under 100 million (100,000,000). Starting with Windows 8.1 the validation limit is 17 million (17,000,000) in each dimension. > [!NOTE]
Other factors might impact how much content can be rendered in a single VirtualSurfaceImageSource. For example, placing a VirtualSurfaceImageSource in a ScrollViewer might further reduce the effective size based on the ScrollViewer's limits.
