The consensus seems to be that this can be achieved by resampling or enumerating all of the GDI calls and converting them to their equivalent. The latter approach would better suit our needs because we would like to retain the constructs. Does anyone know of any commercial or open source libraries/components that support the translation of metafiles into their equivalent GDI+ calls? Failing that, would anyone be interested in doing the custom development? Any points would be greatly appreciated.

It would be a small step to convert to GDI+ instead of PDF. Try contacting them.

Microsoft has a function in v1.1 of GDI+ that appears to do this, but unfortunately the API is not yet available. For my needs, a control capable of rendering metafiles antialiased using drawing primitives would suffice -- whether it's implemented using GDI+, AGG, G32 or ImageEn is arbitrary as long as it's efficient.

In addition to primitives, I also wanted the text to be antialiased. I saw the same kind of posts about converting the metafile records to EMF+ records. In the end, I found the simply rendering the metafile onto a GDI+ metafile did the trick for the font stuff. It may also work for the primitives as well. I just made sure that I set the proper antialiasing settings on the Graphics object that was wrapping the GDI+ metafile.
