[Pharo-project] Graphics with Anti-Aliasing
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
I cc'ed Carla. I'm sure she should know something about this :) On Sat, Jan 22, 2011 at 11:37 AM, Udo Schneider < udo.schneider@homeaddress.de> wrote:

did you check a bit in CUIS or Squeak because I know that there were a couple a little fixes. Now I do not know if this fix your problems. What we would like to do probably over the summer, is to propose a Cairo and openVG back end via a common api: rome like. But this is not for tomorrow, just something we want to have.

All, I'm using the following code. IMHO the line is jagged ... but maybe I'm doing something wrong: 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." CU. Udo On 22.01.11 15:37, Udo Schneider wrote:

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.

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?

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. Udo On 23.01.11 21:12, Denis Kudriashov wrote:

The Windows VM is impressive - you can tell Andreas I said so :) On whole, if there is something to get right in the Squeak/Pharo world, I've come to expect to see it on Windows first - certainly not because of the OS. ________________________________________ From: pharo-project-bounces@lists.gforge.inria.fr [pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of Ricardo Moran [richi.moran@gmail.com] Sent: Sunday, January 23, 2011 3:13 PM To: Pharo-project@lists.gforge.inria.fr Subject: Re: [Pharo-project] Graphics with Anti-Aliasing Mmmm... maybe it is platform related.
