Hello there,
After scouring the net for hours looking for a nice Python package
that would help me build vector graphics and charts, I came to the
conclusion that PyX would be just the ticket. Unfortunately, I'm still
running into some problems.
There seems to be hardly any documentation on getting PyX to run on
Windows. Since some other people on the mailing list have tried, it
seems that it might not be entirely unsupported. Certainly, on my
first attempt to generate one of the graphics I want to do, it worked
fine on Windows as well. However, as soon as I added the text to it,
it errored out:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\Programs\Dev\Python\Lib\site-packages\pyx\canvas.py", line
309, in text
return self.insert(self.texrunner.text(x, y, atext, *args, **kwargs))
File "D:\Programs\Dev\Python\Lib\site-packages\pyx\text.py", line
1199, in text
self.execute(expr, self.defaulttexmessagesdefaultrun +
self.texmessagesdefaultrun + texmessages)
File "D:\Programs\Dev\Python\Lib\site-packages\pyx\text.py", line
899, in execute
self.fontmap = dvifile.readfontmap(self.fontmaps.split())
File "D:\Programs\Dev\Python\Lib\site-packages\pyx\dvifile.py", line
386, in readfontmap
raise RuntimeError("cannot find font mapping file '%s'" % filename)
RuntimeError: cannot find font mapping file 'psfonts.map'
I downloaded ProTexT (or however it's supposed to be capitalized), but
that hasn't helped. Where am I supposed to get a psfonts.map file?
There was one other problem I ran into. One of the graphics I'm trying
to build is rather large, but narrow, with these sizes taken from
c.bbox():
(1.715765 t + 0.000000 u + 0.000000 v + 0.000000 w + 0.000000 x) m
(8.852500 t + 0.000000 u + 0.000000 v + 0.000000 w + 0.000000 x) m
I wanted to have canvas that was basically the same size but with some
margin, but I couldn't get that to work. The weird thing is that it
works when I just use document.paperformat.A0 with fittosize, but when
I specify another size that is closer to the dimensions I actually
(especially with a more fitting width/height ratio), fittosize seizes
to work and, while I get no errors, my output PDF appears empty.
So I wonder if someone could help me out with these issues.
Cheers,
Manuzhai
