WatchMorph was a good starting point. It seems that #line:to:color: does
not use Antialiasing. I.e.
form := Form extent: 640@480 depth: 32.
form fillWhite.
canvas := BalloonCanvas on: form.
canvas aaLevel: 4.
canvas line: 0@0 to: 640@480 color: Color red.
morph := ImageMorph new.
morph image: form.
morph openCenteredInWorld.
"morph abandon."
does not show any antialiasing. Replacing it with
#drawPolygon:color:borderWidth:borderColor does use AntiAliasing:
form := Form extent: 640@480 depth: 32.
form fillWhite.
canvas := BalloonCanvas on: form.
canvas aaLevel: 4.
canvas drawPolygon: { 0@0 . 640@480 } color: Color transparent
borderWidth: 1 borderColor: Color red.
morph := ImageMorph new.
morph image: form.
morph openCenteredInWorld.
"morph abandon."
That's a "solution" I can live with - as unintuitive as it is though ...
Thanks for your help.

See WatchMorph. It has halo memu anti alias. And when it activated
eclipses looks really good.
I tryed it in pharo1.1 standart windows VM

Hi Richo,
could you tell me which Image/VM/OS you where using?
On my System (Mac OS X 10.6.6) Pharo 1.1 and Squeak 4.1 on Cog VM
(r2349) and regular VM (4.2.5beta1U) both show no antialiasing
(image attached)
Is this maybe somehow platform/plugin related?
Best Regards,
Udo

Hi Udo,
Out of curiosity, I executed your code in Squeak and the
antialiasing
works there. Debugging a little, I found a difference in
BalloonCanvas>>#line:to:width:color:. If you update Pharo's
implementation with Squeak's one it works in Pharo as well.
There might be other differences so you might look into that.
I hope this helps.

I'm doing something wrong:

All,
does somebody has a pointer to a graphics
lib/framework/engine
for Pharo
which works with Anti-Aliasing.
My first tests with Balloon2D were disappointing (maybe
I'm doing
something wrong). But even setting aaLevel does not seem to
bring any
result. I.e. the line drawing code falls back to
superclass code
which
simply draws the same jagged lines like always.
Any pointers?
CU,
Udo
