[PyX-user] Gradient Fill and Gradient Line

[S J. S. <swa...@gm...>]

Hello,

I've been getting very good use out of PyX. I want to know how to do a
gradient fill and a gradient line, where the color along a path shifts from
one color to another, hopefully in a customizable way.

[PyX-user] bbox.empty

[Simon B. <si...@ar...>]

Hi,

Finding the bbox of a canvas doesn't seem to work.
For example:

    c = canvas.canvas()

    c.stroke(path.line(0, 0, 1, 1)) 
    c.stroke(path.line(1, 1, 0, 0)) 

    b = pyx.bbox.empty()
    for item in c.items:
        b1 = item.bbox()
        b += b1
    print(b)

The final bbox is empty.

Oh! It's not actually empty, but it is still an instance of
the bbox.empty class. Surely this should be a function, not a
class ? Or otherwise bbox.__iadd__ should just call __add__.

thanks,

Simon.

[PyX-user] How to Passthrough Raw Tikz Commands

[S J. S. <swa...@gm...>]

I've been using Pyx and find it to be a really well designed interface for
pgf/tikz. Development, however, seems to have slowed down. Is there a way
to pass raw Tikz/pgf commands through to access features that are not yet
covered here? Or is there a guide for extending PyX? Or are feature
requests still handled?

Thanks.

[PyX-user] mode setting is deprecated, use the cls argument instead

[Alan I. <ala...@gm...>]

I've been away from PyX for a bit, and I now find (version 0.14.1)
that generating some of my images produced the following warning:
"mode setting is deprecated, use the cls argument instead"

It would be nice if this warning said it was coming from PyX
and even nicer if it pointed to a manual section for transition.
The only mention I can find in the manual is in section 8.3,
and it involves `text.set`.  So I changed
pyx.text.set(mode='latex')
to
pyx.text.set(cls=pyx.text.LatexRunner)
The warning is gone; was that a complete response to the issue?


Separately, it seems that calling `doaxes` after a fill to the
axes location no longer ensures that the axes are drawn on top
of the last bit of fill, which is a problem.  Did something change?
Is there a fix?

Finally, am I correct that 0.15 was never released?
It seemed on the brink...

Thanks for PyX!

Re: [PyX-user] text color problem

[Michael J G. <mic...@us...>]

Hi José

when you use the LaTeX runner with pyxgraphics=True (which is the
default) PyX constructs a tmp file that it feeds to LaTeX (see text.py).
This is the only place that I can think of where PyX can get into
trouble with special characters in your path.

One workaround is to set "tmpdir" in the "text" section of your pyxrc to
a path without any special characters. That way, you can leave your home
directory fully accented ;)

Cheers
Michael

In deed the problem was that the username has an accent. I made a new
username without it and everything worked.

thanks,
Jose

Re: [PyX-user] text color problem

[José M. M. <jos...@gm...>]

well, it is only a guess that the character is not well-read, and I guess
it should happen as well if I import other packages, but amsmath, for
example, is imported with no problem.

Re: [PyX-user] text color problem

[José M. M. <jos...@gm...>]

Hi, thanks for running the code.

The color package is correctly installed, I think, since I can compile
colored text in latex outside pyx.
I printed the full error, which I report below. It seems that at the end
pyx does not find the pyx.def. I searched it in the HD and I found the file
in the correct folder; however, I think I found the problem, my username
has an accent, and clearly tex interprets that utf8 character wrong:
  ! LaTeX Error: File `*C:/Users/JOS\unhbox\voidb@x \penalty \@M \
{}1/AppData/Loc*
*  al/Temp/pyxeg9r80wk/pyx.def*' not found.

Now, is strange that this happens when latex is run by pyx, but not
normally when compiling a document.

best,
Jose

Re: [PyX-user] text color problem

[Michael H. <mi...@sp...>]

Dear Jose,

I tried your code on my machine (Linux) and it works as expected. Maybe you
have a problem with your LaTeX-Installation? What is in the file
errordetail.full? Is the package color installed correctly?

[PyX-user] text color problem

[José M. M. <jos...@gm...>]

 Hi, I'm having problems with text in color. I solved this issue years ago
on my old machine, but now I bought a new laptop, and I installed
everything from scratch (windows os, texlive, anaconda, pyx), and I don't
have a clue of how I solved it before.

Basically, the code is this

from pyx import *
text.set(text.LatexRunner)
text.preamble(r'\usepackage{color}')

c = canvas.canvas()
a = '\\textcolor[rgb]{1,0,0}{x}'
c.text(0, 0, a)
c.writePDFfile('./plots/test')

and this code fails, although is very similar to the example in the
documentation. The full output is this:


Still waiting for LaTeX after 5 (of 60) seconds...
Still waiting for LaTeX after 10 (of 60) seconds...
Still waiting for LaTeX after 15 (of 60) seconds...
Still waiting for LaTeX after 20 (of 60) seconds...
Still waiting for LaTeX after 25 (of 60) seconds...
Still waiting for LaTeX after 30 (of 60) seconds...
Still waiting for LaTeX after 35 (of 60) seconds...
Still waiting for LaTeX after 40 (of 60) seconds...
Still waiting for LaTeX after 45 (of 60) seconds...
Still waiting for LaTeX after 50 (of 60) seconds...
Still waiting for LaTeX after 55 (of 60) seconds...
The timeout of 60 seconds expired and LaTeX did not respond.

    raise TexResultError("TeX didn't respond as expected within the timeout
period.")
pyx.text.TexResultError: TeX didn't respond as expected within the timeout
period.
The expression passed to TeX was:
  \usepackage{color}%
  \PyXInput{4}%
After parsing the return message from TeX, the following was left:
  *
  *(c:/texlive/2017/texmf-dist/tex/latex/graphics/color.sty
  (c:/texlive/2017/texmf-dist/tex/latex/graphics-cfg/color.cfg)
  ! Missing \endcsname inserted.
  <to be read again>
  (cut after 5 lines; use errordetail.full for all output)


I tried the other option for the preamble that is mentioned in the
documentation,

from pyx import *
text.set(text.LatexRunner, pyxgraphics=0)
text.preamble(r'\usepackage[pyx]{color}')

c = canvas.canvas()
a = '\\textcolor[rgb]{1,0,0}{x}'
c.text(0, 0, a)
c.writePDFfile('./plots/test')


which also fails, probably because I did not copy the mentioned files in
the respective paths, which is something I would like to avoid. The full
output is

ignoring special 'color push rgb 1 0 0'
ignoring special 'color pop'

and it actually prints a pdf, but with no color, just in black (because is
ignoring the tex color statements).

What is the solution for this problem? To be honest I don't even understand
what the problem is.

thanks a lot,
Jose Miotto

[PyX-user] encoding of TeX log

[Gert-Ludwig I. <ger...@ph...>]

Hello,

according to the docs, texenc fixes the encoding used in the
communication with (La)TeX. Unfortunately, in general, the log
messages of (La)TeX are not returned in a well-defined encoding.
Specifically, messages containing input from the (La)TeX file are
returned in the fontenc, e.g. T1 (cf. e.g.
https://tex.stackexchange.com/questions/131238/what-controls-the-encoding-of-the-latex-log-file-and-how-to-change-it).
In the following example, this will lead to a UnicodeDecodeError:

from pyx import canvas, text

text.set(text.LatexRunner, texenc="utf-8")
text.preamble(r"""\usepackage[T1]{fontenc}
                  \usepackage[utf8x]{inputenc}""")
c = canvas.canvas()
c.text(0, 0, r'foo föo föo f\"oo f\"oo', [text.parbox(2)])
c.writePDFfile()

The parbox is sufficiently narrow to produce an overfull hbox and
the error message will contain the input string. Independently of
whether the umlaut ö is given as Unicode character or TeX code, it
will be translated into a byte 0xf6 which cannot be interpreted as
UTF-8 encoded character.

As a temporary solution, I set the encoding of MonitorOutput in my
copy of text.py to latin1 because I want to be able to handle input
in utf8. Most likely, however, this is not the best solution...

Best regards,
Gert

Hi René,

change "brochure.append(page)" to "brochure.append(document.page(page))".

A canvas is not a page, and cannot be inserted into a document without wrapping it in a page object.

The "writePDFfile" and similar methods of a canvas are just convenience methods to directly save a canvas into a file for a rather common use case. When creating documents yourself (for example for multiple page documents), you need to properly (i.e. manually) create pages and insert those into a document. Its just the way it is ...

Best,


André

Salut André,

I see: there is no hope before next week ...;)

What do you think about that: get a PS-form of the wanted glyphs
(trough FontForge ?) and translate to Pyx (I made that for some
music glyphs) ?

[André W. <wo...@us...>]

Dear René,

just a very quick response, also for my own reference for the future.

Right now we do not support anything else than the original dvi format as defined by Donald Knuth. Seems like this original dvi format is called version 2, and it looks like there are extensions: http://dvisvgm.bplaced.net/ talks about version 3 (related to etex) and 5 to 7 (related to xetex).

As an additional reference https://tex.stackexchange.com/questions/282763/how-does-xelatex-and-lualatex-extend-the-dvi-format talks about 2 additional commands, 252 (define nativ font) and 253 (set glyphs). Details need to be taken from the .web source as far as I can see. Anyway, those additions might be added to the PyX dvi engine somewhere in the future. But don't count on that in the near future. Given the very slow (but still remaining) development efforts on PyX, this will surely take years to be addressed. I'm sorry for that.

Best,


André

Re: [PyX-user] pdflatex crashes when including PDF created by PyX

[Joerg L. <jo...@us...>]

Hi Micha,

I have tried to reproduce this with the current PyX trunk but obtain a
different (and correct) result (see attached PDF output), which will not
lead to crashes with older pdflatex versions. It seems to me that you
have not fully applied the fixes in r3682.

In addition, you should also apply r3683, which fixes a related bug that
does not lead to a pdflatex crash but nevertheless corrects an incorrect
field name in the PDF font descriptor output.

Cheers,

        Jörg

Now it works. Either I did a mistake applying r3682 or it is also crucial to
apply r1681 (reactivate the pfb to pfa fallback (was likely checked in by
accident during bug hunting)).

Thank you very much! :)

the example compiles without error in the current
debian/stretch texlive environment:
/tmp# pdflatex -v
pdfTeX 3.14159265-2.6-1.40.17 (TeX Live 2016/Debian)

one could check ubuntu 1604 and 1610, which have texlive versions
between jessie and stretch.

[PyX-user] pdflatex crashes when including PDF created by PyX

[Michael H. <mi...@sp...>]

Dear PyX developers,

I have a problem similar to the one fixed by SVN commit r3682: I create a  PDF
using PyX (see image.py). When including this PDF file in a latex document and
compiling, pdflatex aborts:

ts/map/pdftex/updmap/pdftex.map} <./image.pdfInternal Error (0): Call to
Object where the object was type 2, not the expected type 1
Aborted

I have not used the latest developer version of PyX, but I have manually
applied the changes of r3682. Also, pdflatex seems to work with newer version,
but I have no distribution to test this at the moment.

I have attached a minimal example to reproduce the crash. Probably, this is
not a bug in PyX, but a bug with pdflatex.

This is my version of pdflatex (Debian jessie):
$ pdflatex -v
pdfTeX 3.14159265-2.6-1.40.15 (TeX Live 2015/dev/Debian)
kpathsea version 6.2.1dev
