TPDF

• The following macro produed a wrong PDF file. The second page had a black background.

       {
          gROOT->SetStyle("Plain");
          TCanvas*  canvas = new TCanvas("canvas", "canvas", 600, 700);
          TH1F* h = new TH1F("h","ht", 100, -5, 5);
          h->FillRandom("gaus",10000);
          canvas->Divide(2,1);
          canvas->cd(1); h->Draw();
          canvas->Update();
          canvas->Print("test.pdf(");
          canvas->Print("test.pdf");
          canvas->Print("test.pdf)");
       }
       

TPostscript

• Fix a precision problem in the text positionning. When the pad limits along X or Y were very close the text position might be wrong. This was found thanks to the test #15 in stressGraphics. The text position is now computed using double precision variables only.

TASImage

• Horizontal dashed lines having a width greater than 1, were not correct.

TLatex

• Improve the sqrt drawing to avoid the overlapping problem mentionned here https://savannah.cern.ch/bugs/index.php?82436

TGaxis

• The following macro produced two different labelling. Label "3" was missing on the axis "b".

       {
          TGaxis *a = new TGaxis(0.2,0.5,0.8,0.5,0.2,3.5,510,"G");
          a->SetMoreLogLabels(1); a->Draw();
          TGaxis *b = new TGaxis(0.8,0.7,0.2,0.7,0.2,3.5,510,"G");
          b->SetMoreLogLabels(1); b->Draw();
       }
       

TPad

• Add a protection in TPad:Clear() to fix the bug report #78382. An histogram redrawing in a cloned pad produced a segmentation fault.

GX11Gui

• Only call XFreeColors if we are on a <= 8 plane machine (to match calls to XAllocColor). This solves the bug #77329: X11 error clicking on '?' in context menus

TGWin32

• Unmap the window before to destroy it, in order to properly receive kUnmapNotify needed by gClient->WaitForUnmap(). This fixes the problem reported on the forum
