Re: [Pharo-project] Graphics with Anti-Aliasing

by Udo Schneider

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.

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.
