MetaDraw is a special purpose picturebox/image editing component. To your application, it looks like a standard picturebox, but it offers unique support for metafiles - a graphical format well suited to the drawing and/or moving of graphical objects - including the ability to tag individual graphic objects for HyperGraphic/HotSpot applications. Use as a metafile viewer with support for zoom and scroll.
