    <p>
      The TrueType Font to SVG (<code>ttf2svg</code>) application lets you
      convert a range of characters from a TrueType Font into the SVG font
      format.
    </p>

    <section id="running">
      <title>Running the font converter</title>
      <p>
        If you are using the Batik binary distribution, type the following at
        the command line:
      </p>
      <source>java -jar batik-ttf2svg.jar <em>OPTIONS</em></source>
      <p>
        If you are using the Batik source distribution, type the following at
        the command line:
      </p>
      <source>build ttf2svg <em>OPTIONS</em></source>
      <p>
        In both cases, the options are the same:
      </p>
      <source><em>ttf-path</em> <em>[</em><strong>-l</strong> <em>range-begin] [</em><strong>-h</strong> <em>range-end] [</em><strong>-autorange</strong><em>] [</em><strong>-ascii</strong><em>] [</em><strong>-id</strong> <em>id] [</em><strong>-o</strong> <em>output-path] [</em><strong>-testcard</strong><em>]</em></source>
      <p>
        where:
      </p>
      <dl class="options">
        <dt><em>ttf-path</em></dt>
        <dd>
          <p>specifies the TrueType Font file containing the characters to be
            converted,</p>
        </dd>
        <dt><strong>-l</strong> <em>range-begin</em> <strong>-h</strong> <em>range-end</em></dt>
        <dd>
          <p>specifies the range of characters (by codepoint, in decimal) to be
            converted,</p>
        </dd>
        <dt><strong>-autorange</strong></dt>
        <dd>
          <p>automatically determines the available character range, instead of using the
            default, ASCII printable characters (ranging from 32 to 126),</p>
        </dd>
        <dt><strong>-ascii</strong></dt>
        <dd>
          <p>forces usage of the ASCII character map in the font, instead of the
            Unicode character map,</p>
        </dd>
        <dt><strong>-id</strong> <em>id</em></dt>
        <dd>
          <p>specifies the value for the <code>id</code> attribute of the generated
            <code>font</code> element,</p>
        </dd>
        <dt><strong>-o</strong> <em>output-path</em></dt>
        <dd>
          <p>specifies the pathname of the output SVG document containing the
            generated SVG font, and</p>
        </dd>
        <dt><strong>-testcard</strong></dt>
        <dd>
          <p>specifies that a sequence of SVG <code>text</code> elements should be
            appended to the output SVG file to test the characters in the SVG
            font, providing an easy way to validate that generated SVG
            font visually.</p>
        </dd>
      </dl>
      <p>
        For example:
      </p>
      <source>java -jar batik-ttf2svg.jar /usr/home/myFont.ttf -l 48 -h 57 -id MySVGFont -o mySVGFont.svg -testcard</source>
      <p>
        will convert characters 48 to 57, i.e., <code>'0'</code> to
        <code>'9'</code>, in the <code>myFont.ttf</code> file into their SVG
        equivalent in the <code>mySVGFont.svg</code> file, appending a test 
        card so that the font can be visualized.

      <p>
        The TrueType Font converter application is helpful to be able to embed
        font definitions in SVG files. This will ensure that the SVG document
        will look exactly the same on all platform by not relying on system
        fonts.
      </p>
      <p>
        Note that users of the tool should make sure that they have the right
        to embed the font before embedding it in an SVG file and should refer
        to the font license for information. Note that TrueType Font files
        contain a flag that defines the “embeddability” of a font and there are
        tools for checking that flag.
