inkscape scripts

This page contains some scripts which can be used with inkscape.

make path objects

As can be seen in the preamble at the code below, importing inkscape .svg files in libre office or converting them to pdf causes problems: Libre office chops off part of texts and svg to pdf converted files do not show dashed lines correctly. This script helps converting text and dashed line objects to paths.

#!/bin/bash
# This script converts all .svg files in a directory to
# .svg files which have their strokes and text converted
# to path.
# Conversion to path is necessary if files are imported
# in libre office writer or converted to pdf.
# Without conversion, files have incorrect dashed lines
# and text appears to be partly chopped off sometimes.
# 
# The script also converts all processed .svg files to
# .pdf files and merges them into one .pdf file.
#
# This script expects inkscape and ghostscript to be
# installed.
