I do SWGraphics.setAntialias(SWT.ON) to smooth the =
org.eclipse.draw2d.Polygon and would like to find out if there is any =
performance impact?
Thanks
Shannon

While it might be much slower, drawing a simple decoration at the end of =
a connection is still going to be quite cheap. Also, if you use a =
decoration figure or your own clipping logic, the cost is only incurred =
for those decorations in the damaged region.

Is there any other way we can achieve smooth polygons specifically =
diamond and triangle shapes?

It depends on the platform. On win32, the impact is huge. It's an =
order of magnitude slower. On OS X, there is little or no impact.

Hi Shannon,
This depends on your domain and the complexity of your diagram. Consider =
how many things are on the diagram and how many figures must be =
processed.
For GMF based diagrams, we default to anti-alias on, as we like the =
improved smoothed look.
Rational Software Architect makes use of GMF for its diagrams. When I =
open the largest, most complex UML Class Diagram I have in Rational =
Software Architect, I see no difference in performance on Windows XP =
whether anti-alias is on or off.
If someone has a concrete example of how anti-aliasing performs poorly, =
I would be interested in documenting and put in the GEF FAQ on the wiki.
Cheers...
Anthony
