How to remove base64 from SaveAsSVG

[JamesRLamar]

This is building from the script I was developing that is mentioned here, http://forums.adobe.com/thread/1052584.

As my script loops through and converts EPS to SVG, I am consistently getting large amounts of base64 encoding in the SVG which is unecessarily making the file size large. If I strip out the encoding at the beginning of the file, the main image is undisturbed and the file size is about 500% smaller. Below is the script I am currently using. Is there parameter I can invoke to exclude all of this encoding on conversion? I thought the default for options.embedRasterImages was supposed to be false. Thanks!

I managed to dramaticaly reduce the embedded code, by changing some export settings detailed below. It appears to be the fonts embedded as base64 by default. The following works well at reducing the size although not completely eliminating it.

 options.embedRasterImages = false;
          //options.compressed  = true;
          options.includeFileInfo = false;
          options.preserveEditability = false;
          //options.includeVariablesAndDatasets = true;
          //options.slices = true;
          options.fontType = SVGFontType.OUTLINEFONT;
    options.fontSubsetting = SVGFontSubsetting.None;
    options.optimizeForSVGViewer = true;
