Hello people,
as you know I have been playing with Rome a bit. My question is:
Can I use RomeCanvas to make a Morph (or, for instance, ALL of
them) anti-aliased?
In principle, yes, though it's going to be a lot of work.
What is much better supported is Balloon rendering (the engine behind
Squeak's Flash player). Basically, you just send #asBalloonCanvas to
a regular Canvas, set the antialiasing level (up to 4), and draw.
See, for example, WatchMorph. Create one, and enable AA in its halo
menu.
Has someone made efforts in that area? (Tweak maybe?)
Yes, the Rome-Tweak package contains a RomeTweakCanvas that mimics
CTransformCanvas, which is normally used for Tweak rendering. It's
much easier to do than for Morphic because Tweak has a much cleaner
graphics model. You can toggle its usage on and off, it's got a nice
quality boost. The plan was to use this while transitioning to a pure
RomeCanvas, but this effort has stalled.
If not, I would be willing to investigate the possibility
(antialiased graphics is a must for me).
Correct me if I'm wrong, but I would need to see that all the
drawing operations of FormCanvas are supported, right? Or how would
you proceed?
Yes, but there are many places in Morphic that rely on the canvas
being a FormCanvas, and even direct bitblt operations.
P.S. Is this the right place to ask these questions? Or is there a
Rome mailing list?
This isn't exactly newbie stuff, so I'd rather take this to squeak-
dev. There is no Rome list, as far as I know you are the first one
trying to use it for Morphic rendering.
