Latex rendering on linux and windows
by lapnect 27 May '06

27 May '06

Hi, There are two versions of eqtexsvg.py script - one works fine on windows and Tav's version works on linux. So, I decided trying to make a mixed version of eqtexsvg.py using OS detection stuff. Is it safe to detect OS by testing of os.name variable in python ? Posibble names are: 'posix', 'nt', 'dos', 'os2', 'mac', or 'ce' and I assume linux='posix' and windows='nt'. Another question is how to make dynamic dependencies (OS based - if it's possible) in .inx file ? lapnect

Bug pruning.
by Jon A. Cruz 27 May '06

27 May '06

As I was going through looking for bugs to grab, I noticed a few that might be out of date and/or easy targets for removal. If anyone could take a look at them, that could be helpful. [ 1005626 ] Right Mouse Button dialogue pops up during bezier curves [ 1018798 ] open dialog: paste filename, press Enter, wrong file loads [ 1061934 ] visible child in hidden parent [ 1114900 ] vector.tcc error, GCC 3.4.3

Bezier mathematicians anyone ?
by Justin Wikinator 27 May '06

27 May '06

So, this is a callout to anyone who is familiar with the mathematics of beziers, I need your help, generally, but also specifically. Generally, if you would be willing to volunteer as someone I can consult with on bezier math, that would be great, give me a shout. Specifically, I want to write a method that outputs a list of equally spaced points along a bezier BUT, I don't mean equally spaced t-values for the bezier -- I can already do this -- I mean points that are of equal distance along the bezier. I'm almost certain the two are distinct. Any suggestions ? A lot of potential functionality for path effects seem to rest on this ability.

Inkscape 0.44 Bug Bet
by Ralf Stephan 26 May '06

26 May '06

This is to announce I made a bet with Bryce to the tune of EUR 20 that inkscape people are not able to reach 200 points of fixed bugs within a week, payable to the inkscape project if wrong. The date is 2006-Jun-01 07:20 GMT. ralf

Test harness back online, and updated to the latest debian packages (thanks to kees). We're at 11 warnings...

Render Latex Equation fails on Linux distributions
by Raul Durand 26 May '06

26 May '06

Render Latex Equation fails on Linux distributions The Render Latex equation Extension fails. The python file eqtexsvg.py fails in two places: 1. This escript calls latex with -output-directory option wich does not exist in common Latex Linux distributions. It can be solved easily avoiding the -output-directory option using python commands to manage the generated files. 2. This script calls pstoedit with -f svg option but standar pstoedit for Linux distributions do not include a svg driver!! This driver must be installed separately, and seems to be quite hard to find it out for free. Good work. Raul Durand. raul.durand@...400...

Justin, Just use a simple crawler while loop that resamples the interpolated points of the Bezier curve by weighting several points, so that you end up with a very similar curve but with regular point separation (specified at will, optimally the average point interdistance). There are many ways to do this, one is here, the function named "subsample" (incorrectly named, should be "resample"): http://www.pensament.net/java/CurveMorphing.html Albert

Problems with Latex formula extension...
by dsign 26 May '06

26 May '06

The pstoedit version (3.42) installed in Suse 10.0 doesn't accept the command line options passed to it from the eqtexsvg.py extension file. I really love and need this feature, but to be truth I'm not an expert at using LaTeX and satellite command line utilities, so the more I could do was to write a workaround, see it at the bottom. Still remains a problem, present in the original eqtexsvg.py and the adjoint one: when the formula doesn't parses correctly, the script hangs, possibly because LaTeX doesn't leave, but remains in interactive mode; turning Inkscape irresponsive. Any idea of how to avoid that? =============== eqtexsvg.py============================================== import inkex, os, tempfile import xml.dom.minidom import sys import xml_utils def create_equation_tex(filename, equation): tex = open(filename, 'w') tex.write("""%% processed with EqTeXSVG.py \documentclass{article} \\thispagestyle{empty} \\begin{document} """) tex.write("$$\n") tex.write(equation) tex.write("\n$$\n") tex.write("\end{document}\n") tex.close() def svg_xml_open(self, filename): document = xml.dom.minidom.parse(filename) #We have two groups, with a few attributes an some other extravagances #The second group is the interesting one current_node = document.documentElement.firstChild # Move until you find a group node while current_node.nodeName != 'g': current_node = current_node.nextSibling if current_node == None : break copier = xml_utils.XmlCopier( document, self.document) append_this = copier.deepCopyElement(current_node) self.document.documentElement.appendChild(append_this) class EQTEXSVG(inkex.Effect): def __init__(self): inkex.Effect.__init__(self) self.OptionParser.add_option("-f", "--formule", action="store", type="string", dest="formule", default=10.0, help="Formule LaTeX") def effect(self): base_file = os.path.join(tempfile.gettempdir(), "inkscape-latex.tmp ") latex_file = base_file + ".tex" create_equation_tex(latex_file, self.options.formule) out_file = os.path.join(tempfile.gettempdir(), " inkscape-latex.tmp.output") exit_status = os.system('latex -output-directory=' + tempfile.gettempdir() + ' ' + latex_file + '> ' + out_file) if exit_status != 0: sys.exit(exit_status) ps_file = base_file + ".ps" dvi_file = base_file + ".dvi" svg_file = base_file + ".svg" os.system('dvips -q -f -E -D 600 -y 5000 -o ' + ps_file + ' ' + dvi_file) os.system('pstoedit -f plot-svg -dt -ssp ' + ps_file + ' ' + svg_file + '>> ' + out_file) # ouvrir le svg et remplacer #7F7F7F par #000000 svg_xml_open(self, svg_file) # clean up aux_file = base_file + ".aux" log_file = base_file + ".log" os.remove(latex_file) os.remove(aux_file) os.remove(log_file) os.remove(dvi_file) os.remove(ps_file) os.remove(svg_file) os.remove(out_file) e = EQTEXSVG() e.affect() =============== xml_utils.py ============================================== class XmlCopier: def __init__(self, source_document, target_document): self.s_doc = source_document self.t_doc = target_document def deepCopyElement(self, source_element): """ Copies attributes and contents from source_node to target_node """ name = str(source_element.nodeName) target_element = self.t_doc.createElement(name) #Start with the attributes attrs = source_element.attributes for attr_name in attrs.keys(): target_element.setAttribute(str(attr_name), source_element.getAttribute(attr_name)) #Next go with the childs for c in source_element.childNodes: if c.nodeType == 3: new_node = self.copyText(c) else: #Node is assumed to be another element new_node = self.deepCopyElement(c) target_element.appendChild(new_node) return target_element def copyText(self, text_node): the_text = str(text_node.nodeValue) result = self.t_doc.createTextNode(the_text) return result
