textextの入手とインストール

半角文字だけのTeX文書を正常に実行できるようにする

        #self.tmp_path = tempfile.mkdtemp()
        self.tmp_path = 'c:/tmp/textext/'
	self.tmp_base = 'tmp'

    def remove_temp_files(self):
        """Remove temporary files"""
        base = os.path.join(self.tmp_path, self.tmp_base)
        for filename in glob.glob(base + '*'):
            self.try_remove(filename)
        #self.try_remove(self.tmp_path)

日本語を含むTeX文章を入力できるようにする

import inkex
import codecs
import os, sys, tempfile, traceback, glob, re, md5, copy
from lxml import etree

        # Convert TeX to PDF

        # Write tex
        f_tex = open(self.tmp('tex'), 'w')
        try:
            #f_tex.write(texwrapper)
	    sjis_tex = codecs.getwriter('shift_jis')(f_tex)
	    sjis_tex.write(texwrapper)
        finally:
            f_tex.close()
            
        # Exec pdflatex: tex -> pdf
        #exec_command(['pdflatex', self.tmp('tex')] + latexOpts)
        exec_command(['platex', self.tmp('tex')] + latexOpts)
	exec_command(['dvipdfmx', self.tmp('dvi')])
	if not os.path.exists(self.tmp('pdf')):
            raise RuntimeError("pdflatex didn't produce output")

        # Exec pstoedit: pdf -> svg
	exec_command(['gswin32c', '-dSAFER', '-q', '-dBATCH', '-dNOPAUSE',
	              '-sDEVICE=epswrite', '-dEPSCrop', '-r9600',
	              '-sOutputFile='+self.tmp('eps'), self.tmp('pdf')])
	exec_command(['pstoedit', '-f', 'plot-svg',
	              self.tmp('eps'), self.tmp('svg')]
	              + pstoeditOpts)
