Oh and apparently in pdf and ps formats, the filling of the histograms disappears (i.e. only the histogram lines remain but their fill area is empty). I don't know if this problem s related at all to the png problem.

Hi all,

I have created a plotter class that mainly manipulates TH1D's and THStacks (weighting, setting styles etc..) before plotting multiple them on a TCanvas.

The problem I am experiencing is that when I save the canvas to png format, the png image is somewhat corrupted, in the sense that at the half bottom of the picture the top half part is repeated. It's like the picture is "tiled". Has anyone experienced this problem before? Any hints of how to avoid it?
