Sounds like an excersise in rasterization to me.
Sort all the points for Y, and then for X within each of the Y boundaries
then create rectangles for each Y value and each pair of X values such that
you create an array of rectangles that attempt to cover the area. Similar to
the rectangles in a region.
If all Y points are not covered, ie there are horizontal lines in the
resulting set, you'll need to extrapolate ans fill in the blanks somehow.
Possibly by doing a bresenham line-drawing algorithm in between the points
and thenn re-creating and re-sorting the array until you can't add any more
Y lines.
Finally create a region from the rectangle set by taking the union of a
blank region and all the rectangles in the set, use this region to clip the
output of your GraphicsPath.
To draw a line around it for a border you'll have to find one of the many
winding edge-walking algorithms that exist on the net and implement that.
You'll excuse me for not including code, you can see that it'd be a little
too much work for a complete answer.
See the article on extracting a region from a bitmap for at least some of
the techniques mentioned above.
