Example #1

File: makeimage.C Project: leloulight/rootsubtree

void makeimage(const char *MacroName, const char *ImageName, const char *OutDir, bool cp)
{
   gROOT->ProcessLine(Form(".x %s",MacroName));
   if (cp) gSystem->Exec(TString::Format("cp %s %s/macros", MacroName, OutDir));

   TIter iCanvas(gROOT->GetListOfCanvases());
   TVirtualPad* pad = 0;

   while ((pad = (TVirtualPad*) iCanvas())) {
      pad->SaveAs(TString::Format("%s/html/%s",OutDir,ImageName));
   }
}

Example #2

File: makeimage.C Project: A2-Collaboration/root

{
   if (!py) gROOT->ProcessLine(Form(".x %s",MacroName));
   else     gROOT->ProcessLine(Form("TPython::ExecScript(\"%s\");",MacroName));
   if (cp) {

      if (i>0) MN.Remove(i, l);
      gSystem->Exec(TString::Format("cp %s %s/macros", MN.Data(), OutDir));
   }

   int ImageNum = 0;
   while ((pad = (TVirtualPad*) iCanvas())) {

      pad->SaveAs(TString::Format("%s/html/pict%d_%s",OutDir,ImageNum,ImageName));
   }

   FILE *f = fopen("NumberOfImages.dat", "w");
