James,
I've done quite a bit of direct frame buffer/blit code with the 7300
(as well as funding the 800x600 update ;-)
If you, or anyone else, would like access to some of my code (for non-
commercial uses) then I'll look at posting some code - Unfortunately
I use a folding text editor (Interspector) which mangles the raw
source code which makes it difficult to extract...
Functions I've coded include:
* Anti-Aliased Fonts in multiple sizes and horizontal/vertial
orientation complete with kerning.
* Boxes and frames with adjustable line thicknesses and corner radius.
* Icon bliting by using the spare screens as icon stores which are
pre-loaded before my application runs.
* Anti-Aliased line routines.
I must say, for my use (machine user interface) the 7300 has been
very easy to work with and using double buffering, the screen updates
are very quick.
Regards,
PJE
