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.
