PushClip(Nullable<RectangleF>) メソッド

Specifies a rectangle to which all subsequent drawing operations are clipped.

The GcGraphics.Clip object returned by this method implements IDisposable, so this method can be used with the 'using' pattern:

using (g.PushClip(...)) ... in which case the clipping region will be removed when the returned object is disposed.
