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.

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.
