Hi,

   I'd like to take a serries of snap shots. Looking through perfly
I've found a funtion pfuSaveImage which looks like it should do what
I want. However, the saved images only save off the red component
of my object, and nothing of the background. I'm running perf 2.0 on
a RE^2 run Irix 5.3. I've read the FAQ, and all it says is
pfuSaveImage is bogus, and the old mailing list log files don't offer
a solution.

   Does anyone have a solution?

My psudocode program look like :

<init>
<setup pipe>
<setup objects>
<setup ESky>
while (!Done)
{
   pfSync();
   <Trans + Rot Object>
   pfFrame();
   pfuGetEvents(&ViewState->events);
   processKeybdInput();
   pfuSaveImage(snapshot,200,100,512,512);
}

THanks for any light you can shed on the subject.
