Re: saving images

Can you make a small macro showing the problem with SetPaperSize ?

Thank you Adrien.
In my case, I don't see any difference using the batch mode or not. On the other hand, my problem shows up for large images only (but they never exceed the screen); in some sense, below a certain size (that I still don't know), everything works fine.

Maybe I found: I have a command
gStyle->SetPaperSize(var/10.0,20)
The problem comes up when var/10.0 (centimeters) is bigger than the standard a4 paper size. Is it a feature or a bug?

Hi Giovanni,

I experienced problems that sound similar without being exactly the same (sorry if it does not answer your question) so just to share my little experience: The problem occured when the canvas is resized by root because it overfit the screen. I found two solutions, the first one is to launch root in batch mode (root -b), which mean you will not see the canvas, or to instantiate the canvas with an appropriate size. The problem does not occure when you save the canvas as a macro because it is already resized I guess.

Using the batch mode is also the only way I found to obtain High resolution png.

the program that generates my plots is very long and with a complicated input part. Thus, I have tried to generate a macro by File -> Save -> filename.C
Well, it turns out that the macro filename.C works perfectly without problems while the problem still persists in the original program.

I have also observed that files saved in jpg, gif or png formats are fine. The problem appears with pdf only.

Dear experts

I have the following problem in saving images. An image is correctly saved if eps format is used but is wrongly saved if I use pdf. Actually, it partially sliced out, as you can see in the attached files. The print goes by a very standard

c1->Print(file.eps) or file.pdf command

Root Version 5.30/06 10 January 2012 on a Fedora 16 machine.

Thank you in advance,

Giovanni Feverati
