Situation: A Microsoft Windows XP user has a graph with labels -- perhaps with parenthesis or other things that Mathematica likes to render with its own fonts -- that he or she would like to export from Mathematica in SVG format. Solution Instructions: 1. Copy the contents of $InstallationDirectory\SystemFiles\IncludeFiles\TeX\texmf\fonts\afm\wolfram and $InstallationDirectory\SystemFiles\IncludeFiles\TeX\texmf\fonts\type1\wolfram to a new folder, perhaps on the desktop. 2. Use the shareware version of CrossFont from http://www.asy.com/sharecf.htm to convert all the afm files in the new folder to pfm and inf files as well as to convert all pfa files to pfb files. 3. Start -> Control Panel -> Fonts -> File -> Install New Fonts -> Point to the new folder on the Desktop. ->Accept whatever the default options are. 4. Export the graph as PDF. 5. Use Illustrator CS 2 to save the PDF as SVG via File->Save for Web with my recommendation of the following options: A. Subset (embed) only the font glyphs used in the file. B. Select the SVG font specification. C. Embed raster images, if there are any. D. Use the same encoding as that of the SVG's eventual host document. That's it. Notes: Broken Tool Chains The only application I have tried that can correctly create an SVG containing Mathematica's fonts is Adobe Illustrator CS 2. Illustrator CS 1 has problems embedding the fonts. CorelDRAW 12 creates an incorrect SVG, even though it looks nice inside the application when imported from EPS. PStoEdit can't embed the fonts either. Scribus 1.2.1 via Cygwin does not correctly export the Point graphics primitive. Inkscape for Windows can't import PDF or EPS. Skencil 2004-1-20, the latest version for Windows, does not work either; I can't remember why at this point. Fonts Installation Type 1 font installation into Windows is necessary because Illustrator CS 2 does not always read Mathematica's EPS files correctly, because Mathematica can only embed fonts in EPS files, and because Mathematica always writes PDF files with Type 1 fonts. I am not sure if Windows requires .pfa and .inf files. Compatability After all of this, one might think that the SVG would look great in Mozilla Firefox 1.5 Beta. Well, that browser's SVG implementation does not yet support embedded fonts. The Adobe SVG viewer does support embedded fonts. BTW, a good way to verify SVG files is to use Batik, a Java-based cross-platform SVG toolkit. Batik is located at http://xml.apache.org/batik/ BTW, I did make sure to uninstall the Mathematica fonts before I verified my SVGs in Batik. As a result, I am fairly sure the font embedding is correctly done by Illustrator CS 2. -- Chris Chiasson http://chrischiasson.com/contact/chris_chiasson
