Hi Ulrich,
Ulrich,
I cannot understand what you try to do!
My assumption is that you have a TEmbeddedCanvas already paint.
Why do you create another TCanvas ?
Why not to do simply:
{
gROOT->SetStyle("print");// contains SetHeaderPS("175 850
translate");
// to put the plot on top centered
TPostScript ps("jostps.ps", 111);
ps.Range(18, 18);
ps.NewPage();
embcanvas->GetCanvas()->UseCurrentStyle();
embcanvas->GetCanvas()->Draw();
// annotation->Paint(); // a TPavetext object
c1->Update();
ps.Close();
delete c1;
}
The examples given at http://root.cern.ch/root/HowtoPS.html
work correctly.
