MetaDraw WinForms for .Net is the .NET version of MetaDraw ActiveX component. This product has been completely rewritten to take advantage of the infrastructure provided by .NET so you can maximize your development productivity. MetaDraw WinForms for .Net integrates seamlessly with Microsoft's .NET Framework. As a result, you get an easy-to-use, robust Object Oriented Image component to create user-friendly interfaces that meet your development needs.
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.
