Hi,
I am using ROOT 3.03/08 from CVS ca. 8/26) GhostScript 6.0 via GV
3.5.8 on Debian x86, GCC 3.0.4.
I am trying to use the new multi-page TPad::Print method but get odd
behavior. In viewing a 3 page output, as I go down the pages in GV I
see:
page 1 blank
page 2 okay
page 3 okay
page 2 okay
page 1 okay
page 2 blank
page 3 HUGE zoom of lower right corner
page 2 same
page 1 same
page 2 same
page 3 blank
page 2 HUGE zoom of lower right corner
etc.
Appended is some test code (am I using the feature correctly?) and
attached is the PS file.
-Brett.
// test_hist.C
//
// run like: root test_hist.C
// needs: hsimple.root from root/test in CWD
// creates: test.ps
//
TCanvas* canvas=0;
TFile* hist_file=0;
void plot_one ()
{
// canvas->Clear(); // no effect
TH2D* hpxpy = hist_file->Get("hpxpy");
hpxpy->Draw("colz");
}
void test_hist ()
{
hist_file = new TFile("hsimple.root");
gStyle->SetOptStat(0);
canvas = new TCanvas("test","test",1100,850);
canvas->Print("test.ps(");
plot_one();
canvas->Print("test.ps");
plot_one();
canvas->Print("test.ps");
plot_one();
canvas->Print("test.ps)");
delete canvas;
canvas=0;
}
