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.
Richo
