I put together this little utility for converting a color EPS/PDF/SVG to grayscale.<br><br><a href="http://www.tlhiv.org/grayscale/">http://www.tlhiv.org/grayscale/</a><br><br>Selecting &quot;invert&quot; swaps colors from white to black and black to white.  So, using a black/white graphic on a transparent background should transform it to a white/black graphic on a transparent background.<br>
<br>Testing is certainly necessary.<br><br>Troy<br>
