It seems that this problem was in older versions of ROOT, but I could not find any recent information about this. I use root 5.25
I create a TF2 image on canvas created after
gStyle->SetCanvasPreferGL(kTRUE);
with something like mpsf->DrawClone(“glsurf2”);
It displays fine, until I try to print it to a file. Printed image contains just a part of a histogram frame and otherwise is white, regardless format (gif, jpg, png). I tried the same thing with gl samples from the ROOT package and had the same effect - no matter if I try to save from the command line or from the menu. Should I do anything special?

Olivier is right, this part was not finished. You can use ps. Or just make a screen-shot ))
I understand. A shame, since I need to create an animated gif from maany function drawings, thus a screenshot would be a very difficult choice. Perhaps in the future…
Depends what you want to do but if you want to make a seen, change angle zoom… you may capture a session using the event recorder (in the Tools menu of TCanvas) of course that will not help if you want to put it on the web.
I think that won’t work. Unfortunately I modify a 2D function parameter than redraw it. Animation shows this function dependence on the modified parameter - like an evolution in time.

Well, at least this should definitly work with non-gl version and with root prior to 5.22
When drawing with glsurf2 (in my case) option, there is a rectangular frame around the histogram, gowing through axis labels etc. I tried drawing with “fb bb” option, but it does not help. How to remove that frame?

Can you, please, show a picture? I do not have the trunk version of ROOT.[/quote]
Do not see any special frame, “growing through axes, labels”. Both are glsurf2.
fb bb are ignored in gl. Back box always present (due to the slicing I have for different “glxxx” options).
It took me a while to find out when it happens. I attach the script.
It seems, that the frame is drawed, when I modify axis titles after the function is drawed.
This is important, when I do something like TF2 tf = (TF2)f->DrawCopy(“glsurf2”);
and than operate on tf to get title etc. Important when drawing the same function, but slightly modified, in two pads. test_frame.C (261 Bytes)
