Hi,

We have a diamond polygon in a gef based application. The diamond polygon
subclasses from org.eclipse.draw2d.Polygon. The outline of the diamond
borders is rough. I noticed that DiamondFigure of the logicdiagram in gmf
looks pretty smooth. Please see the attachment. I'd like to know if there is
a quick way to smooth the polygon border without depending on the whole gmf
plugins.

Help is greatly appreciated.

Shannon,

We use advanced graphics mode in GMF. You can try turning on advanced
graphics / anti-alias in your Graphics object.

Graphics.setAntialias(SWT.ON);

This is only supported on some platforms though and can cause problems
if turned on on platforms that don't support it.

Regards,
Cherie

That is actually pretty cool!

Can one of you refer me to a resource, or give me an example, about
creating diamonds? (I've tried some, but they have "invisible squares"
around them).

I'd also like to make some triangles later :)

Regards,

Tomas

Thanks for the response. Graphics.setAntialias(SWT.ON) does work very well
to smooth the diamond polygon. I have a further question which I posted in
gef news group early on today. Is there any performance impact due to to
this setting?

To create diamond polygon, subclass from org.eclipse.draw2d.Polygon and
create diamond points.
