Hello,
I'm using root of the CVS of today.
When I do the following:
h = new TH1F("","",1,0,1);
h->Draw();
gPad->SaveAs("test1.eps");
I get a eps file which looks ok.
However, if I do (I want to save the current gStyle
in order to modify it and go back to the old style
when returning e.g. from a subroutine):
old_style = gStyle;
gStyle = new TStyle(*gStyle);
h->Draw();
gPad->SaveAs("test2.eps");
I get a broken eps file, i.e. the bounding box is 0 0 0 0.
I saw that the two fields
TStyle::fPaperSizeX
TStyle::fPaperSizeY
are not copied in TStyle::Copy (in fact, these are the only
fields I found which are not copied).
Here's a patch (After which the example works properly):
~ROOTSYS > cvs diff -c base/src/TStyle.cxx
Index: base/src/TStyle.cxx
