Dear VisAD LIsters,I received this email from an Apple engineer and I am following up with them on the apparent OS X 10.1 problem.
Truly yours, John Anderson ps. GO APPLE!
hi John, To answer your original question, you control the antialias by using com.apple.macosx.AntialiasedTextOn and com.apple.macosx.AntialiasedGraphicsOn flags. Here is an example of how you use them: java -Dcom.apple.macosx.AntialiasedTextOn=true -Dcom.apple.macosx.AntialiasedGraphicsOn=true -jar JavaApp.jar Remember that the developer is able to change these setting programmatically within their code. In such case there is nothing you can do. From your description, it looks to me like the antialiasing is actually off. In such cases the Quartz engine produces really ugly output, ie. boxes instead of single points, rectangles instead of lines. The CoreGraphics team is aware of the problem and are working on this. I downloaded VisAD to see the problem you describe, but all the examples I tried require Java3D, which is not supported by MacOS X yet. Please tell me what examples do you run to see the problems. cheersVon: John Philip Anderson <jpanderson_215@xxxxxxxxxxx> Datum: Mo, 01.

Dear Apple-Java Developers, I use the "VisAD" (Visualization for Algorithm Development) numerical graphics package. http://www.ssec.wisc.edu/~billh/visad.html It worked great, until I upgraded to OS X 10.1. Now, the Java2D graphics appear distorted. Curves are now lines, points are now boxes and etc. I suspect that the Quartz "anti-aliasing" functions are the problem. Although, OS X 10.1 Java Release Notes discuss this issue, I do not know how to turn "anti-aliasing" off. Specifically, I would like to know what Object is supposed to call "setRenderingHint()" to turn "anti-aliasing" off within the code. Likewise, my system cannot find "com.apple.macosx.AntiAliasedTextOn" from the "java" command line nor within code. And of course, I can not run MRJAppBuilder nor Project Builder because I do not have the new Developer Tools yet. Can anyone help me? Truly yours, John Philip Anderson <br><br><br> John Philip Anderson 215 West Newman Road Okemos, Michigan 48864-1332 Email: jpanderson_215@xxxxxxxxxxx Telepone: (517)349-6131
