This is my current progress. The ps image looks much better that
xpm image, I have not realized this before.
I have not looked at the code so sorry if I say something wrong here.
Do you mean "better" after conversion xpm -> ps happened?
Some problems other than black-and-white 2D image:
1. Title not shown in .ps format.
Oh yes, I think that was one of the problems when I experimented with it.
2. Image size needs adjustment in *.tex. (Currently too big.
I guess a new tex package is required for auto resizing.)
Yep. I also remember that. The problem for me was that the .ps has no
size and the .tex file does not say in which size it wants the picture.
So even an auto-resizing does not help much. I think the best would be
to add some size information into the .tex file. But that was too much
for me at that time.
3. "smooth" style image is not shown.
What exactly does that mean?
BTW, can be perhaps work on a branch of your github repo. I do not so
much like patches in emails when we have git already.
Eventually, the .ps image creation must be fixed.

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.
