Problem taking screen shot (Squeak 4.1 Ubuntu 10.04)

I attempted to take a screen shot of my Squeak 4.1 image (I am running
Ubuntu 10.04) using "print PS to file ..." but it crashed with error:

shotDSCPostscriptCanvas(Object)>>doesNotUnderstand:
#frameAndFillRoundRect:radius:fillStyle:borderWidth:borderColor:

in PluggableButtonMorphPlus>>drawOn:

where shotDCSPostscriptCanvas is a DSCPostscriptCanvas.

Is this a known problem?/ should I generate a bug report?
Is there another way to generate a screenshot such as a gif file?

Regards,

Ralph Boland

P.S. I ran into a similar problem with Squeak 10.2.

A fix would be better ;)

The PostScript export tries to render all morphs as post script objects, this is not a pixel-screenshot. It cannot reproduce everything correctly but it will try.

Yes, it's in the halo menu's "export..." sub menu.

The PostscriptCanvas is a seprate hierarchy than FormCanvas, so you
might try moving
frameAndFillRoundRect:radius:fillStyle:borderWidth:borderColor: up to
Canvas; I haven't tried it or researched it, but I had a similar
problem with balloonFillOval:... back in 3.9 and that was my
solution..

I've just replaced the menu entry with a simple 'make screenshot' that
makes a screenshot and saves it to a file named SqueakScreen.X.png.
Holler if you want postscript stuff back in the menu (but send a fix
first! :-)
