Synopsis
This class implements a complex graphics path that can be used to
encapsulate a number of different drawing elements in a single
container. It can be used in conjunction with the
System.Drawing.Graphics.DrawPath() and
System.Drawing.Graphics.FillPath() members to
render outlines or filled shapes. The FillMode
specifies the winding mode for filled shapes. If the path is an open
shape, the system automatically adds a straight line to close the
path if it is to be filled; this does not affect outline drawing.
The path can also be used for hit-testing. The
IsOutlineVisible() method will widen the path
with the specified pen, and then return a value indicating whether a
particular point is to be found under that path. Note that this is
non-destructive, whereas the Widen() method
followed by IsVisible(), while logically similar,
will irreversibly flatten the path first. (See below for information
on flattened paths.) In a similar vein, GetBounds() will give you the minimum containing rectangle for the
path.
A path consists of one or more figures. A figure is a connected set
of drawing objects. A figure is automatically started when the path
is created, and you can then use the various AddXXX() methods to insert shapes into the path. Those shapes are
not actually inserted as-is, but approximated with a set of straight
line or Bezier spline segments.
You then call CloseFigure() if you wish to create
a closed shape and start a new figure, or alternatively call
StartFigure() ...
