Hi,

I was directed here by an anonymous comment on my blog (link at sig):

“I know its not the same as what you are working on but from what I can tell it may be an idea to have a look at : [here]
From the looks of it they are rewriting large chunks of RISC OS”

I’m not sure if that’s entirely true (this posting seems to be the most relevant), but the Compatibility library in ROLF may be of some interest to you.

But GDI+ given us an easy-to-use .NET API which allows us to quickly and easily implement much of what we need to cover. Our VDU drivers are pretty well decoupled from the actual rendering mechanism, so it won't be much work to provide a rendering backend for another API, such as GDI as you suggest, or possibly OpenGL to be more cross platform. @Richard Russell

I thought it was one of the limitations of GDI+ that it provided no equivalent to GDI's SetROP2 functionality.
