UseInkscapeSVGImages

As of version 1.6.6 LyX directly supports SVG files - only librsvg or Inkscape needs to be installed on your computer. To enable the default support on Windows, edit preferences and add the path to Inkscape to the paths section (it appears that the path entry may be case sensitive, so use the correct letter casing on the path, even on Windows). Then use Tools | Reconfigure. If you open up the Converters preference again, you should see new entries there for SVG to PNG, SVG to EPS, and SVG to PDF. Once you have them, everything should work fine. You do NOT have to add the converters yourself; they will be automatically added when LyX detects Inkscape on the path during a reconfigure operation. If they're not there, check the path you entered and ensure that you have matched the case perfectly, and that the target directory exists, and that inkscape.exe is there.

Include SVG Images in LyX

The are three possibilities based on Inkscape, Apache Batik and librsvg. Please read details below about first of these two techniques.

Inkscape

Inkscape from http://www.inkscape.org/ can be used to configure LyX to directly include .svg images and automatically generate PNG preview images in LyX, PDF for pdflatex, and EPS for latex. Just add an SVG file type and conversion rules as described below (this is #3349 enhancement request in LyX's Trac.)

Windows

When installing LyX using the alternative installer, Inkscape is automatically used to convert and display SVG images.

Alternatively you can add support for SVG manually:

1. Install Inkscape
2. Adopt your LyX Preferences as follows:
   • In the Section Paths add to Path-Prefix the directory where the inkscape.exe is located.
   • In the Section File Formats
     • Fill in the text fields with the following values
       Format: svg
       GUI-Name: SVG
       Extension: svg
       Viewer: inkscape $$i
       Editor: inkscape $$i
     • Make sure the Vector graphics format checkbox is checked.
     • Important: Press Add
   • In the Section Converters
     • Fill in the fields with the following values
       From: SVG
       To: PDF
       Converter: inkscape --file=$$p/$$i --export-area-drawing --without-gui --export-pdf=$$p/$$o
     • Important: Press add
     • Fill in the fields with the following values
       From: SVG
       To: EPS
       Converter: inkscape --file=$$p/$$i --export-area-drawing --without-gui --export-eps=$$p/$$o
     • Important: Press add
     • Fill in the fields with the following values
       From: SVG
       To: PNG
       Converter: inkscape --without-gui --file=$$i --export-png=$$o
     • Important: Press add
   • Press Save

Finally you need to reconfigure LyX.

Linux

You can configure LyX in a few steps:

• Install Inkscape
• Update 2009-02-23: With LyX-1.6.1 on Ubuntu 8.10, the LyX insert->graphics menu will allow the insertion of SVG files without any customization of the LyX Preferences. Output documents can be viewed without any configuration changes. However, LyX will not be able to launch the SVG editor (The right-click on the graphic to edit the SVG file will not work). The first set of steps outlined next is needed to let LyX know that the editor program is the executable "inkscape". The end result of that first set of instructions will be new lines in the $/.lyx/preferences file's FORMATS section:

  \format "svg" "svg" "SVG" "" "inkview" "inkscape" "vector"

• Adapt your LyX Preferences as follows (The dialog entries are bold.)
  • In the Section File Formats
    • Fill in the text fields with the following values
      Format: svg
      GUI-Name: SVG
      Extension: svg
      Viewer: inkview
      Editor: inkscape
    • Important: Press add
    • Make sure the Vector graphics format checkbox is checked.

You need to restart and maybe reconfigure LyX.

MacOS X

Under MacOS X, it should work just as described in the Linux section. You need to provide the full path to the Inkscape executable, on my system, this is: /Applications/Multimedia/Inkscape.app/Contents/Resources/bin/inkscape because I have Inkscape.app installed in /Applications/Multimedia.

Hints

it might work out of the box

On 3/17/2008 Steve Litt observed in LyX version 1.5.3 that SVG files could be directly placed in the LyX file, even without defining converters for SVG. Your mileage may vary. (Others reported that this produces a bitmap graphic with bad quality)

preview

Some have found using convert (ImageMagick) works better for the preview: Leave out the SVG -> PNG definition and LyX will generate the preview the default way.

text export bug

There is a bug in Inkscape 0.44: It does not export text correctly to EPS if the font name has spaces in it. In order to succeed in exporting text, it can be converted to "paths", by using the command inkscape --export-bbox-page -T --without-gui --file=$$i --export-eps=$$o (The text cannot be processed by psfrag after that (see psfrag below).) in the conversion from SVG to EPS, that is the same command used in the instructions above with the -T (--export-text-to-path) option added.

psfrag

You can use psfrag (in ERTs) to replace text in the images with LaTeX Text and formulas (It would be great if LyX would support that without ERTs!).

Get the right size

If the SVG is converted to EPS, the size of the resulting graphic is automatically set to the size of the content. For both, bitmap and PDF output, by default the size is set to the "paper-size" of the canvas (letter or A4). In order to get a graphic that can be input in a LyX document, the Inkscape drawing must be sized right. Either add --export-area-drawing to the SVG->PDF converter definition (see above) or, after your drawing is complete, do the following:

1. File->Document_Properties.
2. Uncheck all checkboxes in the Borders section.
3. Select everything in the drawing. (either with Strg-A or dragging a rectangle around all elements with the mouse.)
4. Click the "fit page to selection" button.
5. Move both scrollbars to their centers and verify that the picture is still visible.
6. If the picture is not visible, exit without saving and try again.
7. If the picture is still visible, File->Save.

Correction 18/05/08: setting the figure size in Inkscape's File->Document_Properties seems to be mandatory, while the --export-area-drawing doesn't seem to do anything.

Correction 11/25/09: --export-area-drawing is working for export to pdf and png since Inkscape 0.47.
