Property Value

The zoom factor used to display the image.

You can get and set this property when the SizeMode property is RasterPaintSizeMode.Normal.
This property is read only when the SizeMode property is set to any other value. When SizeMode is set to RasterPaintSizeMode.Stretch, the zoom factor is the smallest of the Width or Height zoom factors (the aspect ratio is not preserved).
