If i run any of the examples which output some text I get the following error message:sieck@acertm:~$ python /usr/lib/python2.1/site-packages/PyX/examples/hello.py Traceback (most recent call last): File "/usr/lib/python2.1/site-packages/PyX/examples/hello.py", line 4, in ? c.text(0, 0, "Hello, world!")

Now all PyX examples work. The meaning of the encoding files *.enc you mentioned and what you mean by "you should better extract the enclosing font information" is not clear to me yet. Thanks for your quick response. Alexander ---------------------------------------------------------------------- Comment By: André Wobst (wobsta) Date: 2003-10-08 23:06 Message: Logged In: YES user_id=405853 I see. Point is, that the package installs the fonts but does not automatically include them in the file psfonts.map (used by dvips for example). This file contains some information about the available PostScript-Fonts. When you request cmr10 for example, there should be such an entry in the psfonts.map file. (Run "kpsewhich psfonts.map" to find this mapping file; it should be located at /usr/share/texmf/dvips/config/psfonts.map.) Although there are mapping files for the Computer Modern Roman fonts available in your debian distribution (stable, isn't it), they do not contain proper encoding information. Instead of using those information from /usr/share/texmf/dvips/bluesky/psfonts.cmr, you should better extract the enclosing font information. You should be able to run test.py in the test directory after extraction. You can then install this psfonts.map and *.enc files in the appropriate texmf directory to make it globally available. You can either install it into something like /usr/local/share/texmf/dvips/psfonts or in your home directory ~/texmf/dvips/psfonts. See "kpsewhich texmf.cnf" about your TeX related search path configuration.

I have installed tetex-extra: sieck@acertm:~/packages/PyX-0.4.1/examples$ find /usr/share/texmf -name cmr10* /usr/share/texmf/fonts/type1/bluesky/cm/cmr10.pfb /usr/share/texmf/fonts/tfm/public/cm/cmr10.tfm /usr/share/texmf/fonts/source/public/cm/cmr10.mf sieck@acertm:~/packages/PyX-0.4.1/examples$ ls /usr/share/texmf/fonts/type1/ adobe bitstrea bluesky hoekwater public urw But for all examples with text-output, e.g. hello.py, I still get the error: RuntimeError: no information for font 'cmr10' found in font mapping file When I did run make in /PyX-0.4.1/manual/ the first time, there was a message about some files that couldn't be created, a request to rerun it and finally the same error as above. After the rerun it finished without this error message and manual.dvi was created. Are there any environment variables I have to set or does one need to initialize the Type1 fonts? I rebooted after installing tetex-extra, to initialize tetex or kpathsea, but this didn't help. In the docu I only found a hint to mktexls-r, but this is only to speed kpathsea up, right? Regards Alexander ---------------------------------------------------------------------- Comment By: André Wobst (wobsta) Date: 2003-10-07 23:48 Message: Logged In: YES user_id=405853 It's nice to see that you could get distutils working. You are totally right about the python-dev package you need to install for that. It's quite likely that you are missing just one last point now: You need the TeX-Fonts in Type1 format (a scalable font format from Adobe available in a direct PostScript version (called *.pfa) and a packed version of it (called *.pfb) -- the later are usually distributed and PyX needs it). This is nice to have for tex&dvips as well, since you are not stick to the metafont pk-version of the fonts anymore (which has some advantages, e.g. in pdf creation and other things). The type1-Fonts are available in the debian package tetex-extra. Just install this package to get the files like cmr10.pfb ... then try again. HTH, Andre ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2003-10-07 14:35 Message: Logged In: NO Hello, since I couldn't find the distutils for Python2.1 "python setup.py install" failed with "No module distutils.core". Therefore, I extracted PyX-0.4.1.tar directly to ../lib/python2.1/site-packages. With this I could produce the example box.eps, but the examples with text-output produced the message given above. In the meantime I learned that since Python1.6 the distutils module is in python2.x-dev and installed it. Then I run "python setup.py install" and removed the PyX directory in site-packages. This solved the problem mentioned above. Unfortunately, now something is wrong with the TeX fonts: === start of output === sieck@acertm:~/packages/PyX-0.4.1/examples$ python hello.py Traceback (most recent call last): File "hello.py", line 6, in ? c.writetofile("hello") File "/usr/lib/python2.1/site-packages/pyx/canvas.py", line 936, in writetofile for pritem in self.prolog(): File "/usr/lib/python2.1/site-packages/pyx/canvas.py", line 661, in prolog result.extend(cmd.prolog()) File "/usr/lib/python2.1/site-packages/pyx/text.py", line 1780, in prolog return result + self.texrunner.prolog(self.dvinumber, self.page) File "/usr/lib/python2.1/site-packages/pyx/text.py", line 2086, in prolog self.getdvi() File "/usr/lib/python2.1/site-packages/pyx/text.py", line 2080, in getdvi self.dvifiles.append(DVIFile(dvifilename, debug=self.dvidebug)) File "/usr/lib/python2.1/site-packages/pyx/text.py", line 685, in __init__ self.readfile() File "/usr/lib/python2.1/site-packages/pyx/text.py", line 1087, in readfile state = self._read_page() File "/usr/lib/python2.1/site-packages/pyx/text.py", line 1045, in _read_page file.read(file.readuchar()+file.readuchar())) File "/usr/lib/python2.1/site-packages/pyx/text.py", line 773, in definefont self.fonts[num] = Font(fontname, c, q, d, self.tfmconv, self.debug > 1) File "/usr/lib/python2.1/site-packages/pyx/text.py", line 516, in __init__ raise RuntimeError("no information for font '%s' found in font mapping file, aborting" % name) RuntimeError: no information for font 'cmr10' found in font mapping file, aborting === end of output === "libkpathsea-dev - kpathsea.a and include files for teTeX" is installed. The environment variables in /etc/texmf/texmf.cnf seem to be in agreement with the documentation. A file cmr10.tfm does exist: sieck@acertm:~$ find /usr/share/texmf -name cmr10* /usr/share/texmf/fonts/tfm/public/cm/cmr10.tfm /usr/share/texmf/fonts/source/public/cm/cmr10.mf I can use LaTeX separately without problems, e.g. article.cls and german.sty and the fonts are found. I am not sure whether the problem is caused by my environment or by PyX. Regards Alexander ---------------------------------------------------------------------- Comment By: André Wobst (wobsta) Date: 2003-10-06 08:46 Message: Logged In: YES user_id=405853 I could not yet reproduce your problem. It would be really nice if you could do some tests in order to better trace down the problem. First of all, I'm wondering that you've installed the examples systemwide (this would not be the case when you run "python setup.py install" in the pyx directory --- which is the suggested way to install pyx). The PyX directory in /usr/lib/pythonx.x/site-packages should not contain uppercase characters. You can already see some strange behavior that pyx in taken not from /usr/lib/pythonx.x/site-packages/pyx but from somewhere in your home directory. I expect this to be due to your way of installing pyx. Could you first of all try to fix this and the tell me, if the problem remains ... By the way, I should note that pyx indeed tries to create a temporary file handed over to TeX. This file has a temporary name and is removed after TeX should have read it. The file is created in the local directory (all these things are build in order to come over some TeX limitations). However, since the creation of the file should have been done at that point your problem occures (otherwise you should have got some exception earlier), you might be able to see that file (you might need to turn off the atexit call to cleen the temporary files in text.py). On the other hand, TeX said in the example above, that it could not read that very file. Still, very strange ... ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=442886&aid=817717&group_id=45430 |
