extension: save as SVG

Postby caseygadd » Thu Mar 15, 2018 2:39 pm

I am trying to write an extension that will save the selected as an SVG. I have been trying to find an example of scripting a "save as" call. I have had little luck. does anyone have an example of doing a save as svg with python?

There is some documentation on the website, and you can email the developers mailing list or come chat on IRC for help. Forum users aren't usually developers so I don't know har far you can get here with this.

You can export to plain SVG ( -l, --export-plain-svg=FILENAME, see https://inkscape.org/en/doc/inkscape-man.html), or use the development version that supports saving as Inkscape SVG also (see http://wiki.inkscape.org/wiki/index.php ... mmand_Line).

Or you can use Xverbs in current Inkscape: http://wiki.inkscape.org/wiki/index.php/Using_xverbs

I want to do the save while the file is open. is that possible with xverb? I thought it was a command line utility. this is what I have so far but it does not create a working svg file.

Code: Select all

#! /usr/bin/env python
# -*- coding: utf-8 -*-

import inkex       # Required

class MyExtensionName(inkex.Effect):
    def __init__(self):
        inkex.Effect.__init__(self)
        self.OptionParser.add_option('-x', '--something', action='store', type='string', dest='optionName',
                                     default='defaultvalue', help='Helper text for this option')

    def effect(self):
        option = self.options.optionName
        self._main_function(option)

    def _main_function(self, option):
      svg = self.document.getroot()
      f=open("C:\Users\casey\export.svg","w+")
      f.write(str(svg))

if __name__ == '__main__':
    MyExtension = MyExtensionName()
    MyExtension.affect()

Via extensions, it's possible to call a second Inkscape instance that works on the open file. You can do anything with it that you can do with Inkscape command line.

See for example https://gitlab.com/su-v/inx-pathops/blo ... ps.py#L178 .
