Sets the location and size of the rectangle.
The width and height of the rectangle are set to the new width
The rectangle is then moved to the supplied position while
maintaining the width and height. The corner moved to the location
is indicated by the Pin
property. The default pin corner is the bottom left.
The overload taking an XRect copies the effective location and
size. It behaves as if this XRect and the parameter XRect use the
default Pin and the default
coordinate settings (Doc.TopDown and Doc.Units) so it functions
differently from the other overload and from copying using String. Pin is not copied.
For example suppose you have a Doc object (called doc) for which
you have set the Doc.Units to mm and also a separate XRect (called
rect) that you have created. If you call rect.SetRect(doc.Rect) the
rect will contain coordinates in points rather than mm. Similarly
if you call doc.Rect.SetRect(rect), the point based units within
the rect will be converted to mm for insertion into the doc.Rect.
So there is an automatic conversion between coordinate systems.
