Introduction

In order for Inkscape to make use of an external script or program, you must describe that script to inkscape using an INX file. See the inkscape share directory for examples. The INX file allows the author to:

  • label strings for translation
  • define parameters
  • chain extensions
  • etc

Be sure to read through the INX files that come with Inkscape. Nothing beats a working example.

Localisation of extensions

To allow localisation of strings in extension for Inkscape, some xml tags have to be adapted to variant readable by intltool. It means that tags or parametres has to have "_" prepended to their name, e.g. <_name>name of extension</_name>

Also the path to the extension has to be included in POTFILES.in file to tell intltool where to look for translatable content.

Usefull information, before this section gets fully updated, can be found at Ted's blog.

Example

More example INX files are available in the Inkscape distribution or in the Inkscape repository.

<inkscape-extension>
  <_name>{Friendly Extension Name}</_name>
  <id>{org.domain.sub-domain.extension-name}</id>
  <dependency type="executable" location="[extensions|path|plugins|{location}]">program.ext</dependency>
  <param name="tab" type="notebook">  
    <page name="controls" _gui-text="Controls">
      <param name="{argumentName}" type="[int|float|string|boolean|description]" min="{number}" max="{number}"
        _gui-text="{Friendly Argument Name}">{default value}</param>
    </page>
    <page name="help" _gui-text="Help">
      <param name="help_text" type="description">{Friendly Extension Help}</param>
    </page>
  </param>
  <effect>
    <object-type>[all|{element type}]</object-type>
      <effects-menu>
        <submenu _name="{Extension Group Name}"/>
      </effects-menu>
  </effect>
  <script>
    <command reldir="extensions" interpreter="[python|perl|ruby|bash|{some other}]">program.ext</command>
  </script>
</inkscape-extension>
