Re: [ROOT] Colors in PS prints

Hi Rene,

Sorry,

I was wrong - colors greater than 100 do not work.
As fars as I remember:
     100+colornumber - dark version of a color.
     150+colornumber - light

this is the macro Dmitry.C:
{
TCanvas* c = new TCanvas("test","test",800,600);
c->cd();
TPad* pad = new TPad("pad","pad",0.25,0.25,0.75,0.75);
pad->SetFillColor(108);
pad->Draw();
c->SaveAs("canvas.ps");
}

root -b -q Dmitry.C produces the first PS file I attached (canvas.ps)
The color of the Pad is far from being green

Running the same macro interactively produced the second PS
attached PS file (canvas1.ps) with the right color.

regards,
Dmitri Litvintsev
