Hi Qian,
No. I think there is no reason to convert .xpm for the book.
Any way to produce the final picture that is included in the book is fine.
As far as I know, .xpm might be needed for HyperDoc.
Otherwise, I would be super-happy, if we can generate the pictures for
the book without X.
Let me know what you are doing. It would be possible to inject code that
while generating the .xmp, some other code generates .ps.

Hi Ralf,
I noticed that in the creation process of book.pdf,
you convert .xpm (bitmap) image to .ps format.
But "draw" in FriCAS can create ".ps" (vector) image directly.
I'm trying to use this better quality for the book.
So I'm asking there's no particular reason to choose
bitmap image over vector image, right?
There is a trouble: currently our 2D Postscript output is black and
white only (no colors). So there is some extra work to do,
either use Postscript only for 3D, or modify Postscript output
so that it can handle colors also for 2D.
BTW. There is long standing issue that our 3D Postscript output
needs connection to X server. It would be good to make it work
independently of X.
