+    <td>By default, ImageMagick renders SVGs with <a href="http://www.inkscape.org/">inkscape</a> if Inkscape is in your execution path; otherwise <a href="http://developer.gnome.org/rsvg/">RSVG</a>. If neither is available, ImageMagick reverts to its internal SVG renderer (called MSVG). The default resolution is 96 dpi. Use the <a href="<?php echo $_SESSION['RelativePath']?>/../script/command-line-options.php#size">-size</a> command line option to specify the maximum width and height. (<samp>-size</samp> is currently ignored by the Inkscape renderer due to a limitation on the Inkscape side.) If you want to substitute entities and you trust the SVG source, enable this option: <samp>-define svg:substitute-entities=true</samp>. If you want to render a very large SVG and you trust the source, enable this option: <samp>-define svg:parse-huge=true</samp>. If RSVG is installed and you want to render an SVG using RSVG, add <samp>rsvg:</samp> just before the file name. If you want to render an SVG using MSVG, add <samp>msvg:</samp> just before the file name.</td>
