I'd like to use the same algorithm to render to the screen and to the printer, simply swap out the device context.
The Microsoft MFC library takes this approach and, IMHO, it is the best way to go.
That's okay for simple things, but for any serious printing work you need to know you're talking to a printer. For example, you may need to embed postscript in your output stream.
I'd like to look at how OS X is able to make a PDF of everything. Observing that capability lead me to believe that you could simply swap out the underlying device. Is this still a way to go, using the same algorithm, but adding an object to represent the context, screen, printer, etc.? -- Alan Gutierrez - alan@engrm.com
