Generate GDI+ source code by enumerating a WMF file.

Is there anyway to create a program that can generate vb.net GDI+ source code from a windows metafile or an enhanced metafile? I was thinking it would be possible through calling Graphics.EnumerateMetafile, but I don't know if there was a way to convert the metafile records to generate equivilant GDI+ code.
Any ideas?

I'm not following you.... tell us what you're trying do (rather than the technique you want to use)

I apologize for my delay in responding to your question.

What I would like to be able to do is design the graphics in a graphics editor such as Adobe Illustrator, export my art as a vector art file, and have a program generate vb.net code (DrawLine, DrawEllipse, .. and such) so that I can animate different parts of the drawing with code.

A very simple example would be that I go into Illustrator and draw a circle with a red fill. Then I save the art as a WMF or an EMF. Then I run my code generator app which would read the file, and output a text file with the vb.net code: graphics.DrawEllipse(...).

Then in the application I am building, I can paste the code that was generated, and maybe change the fill color based on any number of parameters.

On a much larger scale, this would allow for me to create complex art drawings in a graphics editor instead of having to try and develop all the code for the graphics. Then I could generate the vb.net code from that vector art file, and have the ability to modify pieces of that code for animating the graphics.

Thanks for your time, if I need to clarify anything further, please let me know!

No, I've never heard of anything exactly like that...
However, that concept is part of the idea behind the new the XAML file format.   You create a graphic using a member of the Microsoft Expression Suite (or some other graphics application) and save the graphics as a XAML file.  Then you can open the XAML file in Visual Studio for further processing or for run-time changes.

But, it wont generate VB.Net code for you...

That could be quite useful! Only usable in a WPF application though right?

Here is an example of what I was trying to accomplish, only it generates c++ code:
ArtCode
I also found this site that shows how to enumerate through a wmf file, and allows you to skip over parts of the drawing process:
Enumerate WMF File
Which is why it might be possible to take it one step further and generate the .net code for each step, but the only way I can see that being possible would be to write a class that detected the type of record, and extract the metadata, and use a select case to correlate the record type to a specific graphics object method. And I wasn't sure if that was even possible!
