RE: Changing canvas size

To show where the problem comes from I've run Akira's example with Qt-plugin on and got both images 600 x 600. ( I tested this on windows. I'll check on Linux later)  

 Hope this helps, Valeri

Hello Olivier,

One size is the size of the widget including the frame decoration, another is the size of the TPad image.

Thank you, Valeri

I agree, that is weird. I get also two different sizes:

$ ls -l *.png
-rwxr-xr-x 1 Olivier None 2261 Apr  1 15:22 c1.png
-rwxr-xr-x 1 Olivier None 2382 Apr  1 15:22 c2.png

They should be the same.....

Hello ROOTers,

How can I change the size of a canvas before printing it? The sizes of c1.png and c2.png are different in the following example.

$ cat can.C
{

   Double_t w = 600;
   Double_t h = 600;
   TCanvas * c1 = new TCanvas("c", "c", w, h);

   c->SetWindowSize(w + (w - c->GetWw()), h + (h - c->GetWh()));
   c->SaveAs("c1.png");
   c->SaveAs("c2.png");

$ root
root [0] .x c.C
Info in <TCanvas::Print>: file c1.png has been created Info in <TCanvas::Print>: file c2.png has been created root [1] .q
$ file c1.png c2.png
c1.png: PNG image data, 596 x 572, 8-bit/color RGB, non-interlaced c2.png: PNG image data, 600 x 600, 8-bit/color RGB, non-interlaced
