HwndSourceParameters.SetSize Method

Sets the values that are used for the window size of the HwndSource.

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

public void SetSize(
	int width,
	int height


Type: System.Int32
The width of the window, in device pixels.
Type: System.Int32
The height of the window, in device pixels.

Unlike most methods that take rectangle screen-region measures in Windows Presentation Foundation (WPF), you specify this window size in device pixels, not in the typical device-independent units. If you need to size your window to its content, set SizeToContent to true.

Do not pass 0 (zero) for either the width or height parameters. Although the method eventually succeeds even if you do pass 0, a substantial performance penalty occurs.
