HA: saving a canvas as postscript or pdf

Hi,
you can display PS file with antialising=ON in ROOT itself without gv -> just click on PS file in ROOT browser. It will invoke the same method which used in gv, i.e. running GhostScript program. TCanvas with PS file image will appear. One can save this canvas in any other image format (no need for convert).

Regards. Valeriy

Hi Roger,

Details about the anti aliasing in GV are given here: http://root.cern.ch/root/HowtoPS.html
(at the end)
Nothing is siad about th fact the lines look thicker. I will had some thing in the coming new version of the HowTo's. I agree that xpdf does not seems to have this option ... I will look.

Ah! Thank-you.

I see now that command toggles anti-aliasing. For anyone else listening to this exchange gv can be started with antialiasing on or off like this:

gv [-]-[no]antialias <filename>

xpdf can enable or disable antialiasing for vector graphics like this:

xpdf -aaVector yes || no <filename>

I could not find any means to toggle antialiasing from within xpdf.

Thanks you very much Olivier.
