Hi Valeriy and Valeri :) About this point, as TASImage and libAfterImage are working on my PC, I tried pad2png.C but it does not works because pixmap2asimage is only working on X11 (take a look at ximage.c). Will take a look at this point next week (I will be away this week-end) Cheers, Bertrand. -----Original Message----- From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch] On Behalf Of Valeriy Onuchin Sent: Saturday, April 10, 2004 12:26 AM To: Valeri Fine; 'Andy Buckley'; roottalk@cern.ch Subject: Re: [ROOT] PNG output? Hi Valeri, I meant, recently Sasha Vasko ported libAfterImage http://afterstep.sourceforge.net/afterimage/ to win32. Bertrand Bellenot made correspondent changes to make it available in ROOT (win32gdk). "Strangelly enough, it is not" incorporated in ROOT yet. Regards.
