10.3 and later
With 10.4, I know I can do the following
+ (NSGraphicsContext *)graphicsContextWithGraphicsPort:(void
*)graphicsPort flipped:(BOOL)initialFlippedState;
where the graphicsPort is a CGBitmapContextRef
+ (void)setCurrentContext:(NSGraphicsContext *)context;
Even with that, I don't see how creating a NSView will set up an
offscreen rendering space.

What I want to be able to do is to render an html page into an
offscreen context and then create an image from it.
The advice from the Quartz list was to render the page in a WebView,
create PDF data from it, render that into a CGBitmapContextRef, then
pull the CGImageRef from that.
The key is this has to be done offscreen.
I don't think you need to bother with the PDF data stream in the
process above.
Which OS versions do you want to target?
10.2 and later?
10.3 and later?
10.4 and later?
