It  demonstrates the use of the QNPInstance::writeReady()  and QNPInstance::write() functions.  <p>  To build the example, you must first build the  <a href=xt.html>Qt Netscape Plugin Extension</a> library.  Then type <tt>make</tt> in <tt>extensions/nsplugin/examples/grapher/</tt>  and copy the resulting <tt>grapher.so</tt> or <tt>npgrapher.dll</tt>  to the Plugins directory of your WWW browser.  <p>  <EMBED ALIGN=LEFT WIDTH=49% HEIGHT=300 SRC=graph.g1n    graphstyle=pie fontfamily=times fontsize=18>  <p>  The text file it accepts as input has a title line, then  a sequence of lines with a number, then a string.  The  plugin displays a pie chart of the numbers, each segment  labelled by the associated string.  The user can select  a bar chart view of the same data by selecting from the  menu that appears when they point at the plugin.  <p>  The HTML tag used to embed the graph is:<small><pre>  &lt;EMBED    SRC=graph.g1n    ALIGN=LEFT    WIDTH=49% HEIGHT=300    graphstyle=pie fontfamily=times    fontsize=18&gt;</pre></small>  Note that some HTML arguments (which we have capitalized here)  are interpreted by the browser, while others are used by the  plugin.<br clear>With the simplicity and cross-platform nature of Qt-based plugins,pages like <a href="http://www.netcraft.com/survey/">Netcraft'sServer Graphs</a> can be provided much more efficiently for boththe service provider and consumer.  Data need not be convertedto an image at the server.<br clear>*//*! \page graph.g1nnum label10 A24 B12 C7 D34 E15 F19 G*//*! \example qtimage/qtimage.cpp  <h1 align=center>Display Images in Qt-supported Formats</h1>  <p>  This example displays images which are in any format  supported by Qt.  Combining this with the Qt ImageIO  Extension adds PNG image support to your browser.  It demonstrates the use of the QNPInstance::streamAsFile()  function.  <p>  To build the example, you must first build the  <a href=imageio.html>Qt Image IO Extension library</a>  and of course the  <a href=nsplugin.html>Qt Netscape Plugin Extension</a> library.  Then type <tt>make</tt> in <tt>extensions/nsplugin/examples/qtimage/</tt>  and copy the resulting <tt>qtimage.so</tt> or <tt>npqtimage.dll</tt>  to the Plugins directory of your WWW browser.  <p><table><tr><td valign=top><EMBED src=pnglogo.png WIDTH=256 HEIGHT=192><td valign=top>  This plugin displays a <a href=http://www.cdrom.com/pub/png/>PNG format</a> image.  <p>  New image format can be supported by  adding new image I/O handlers to the Qt library  (see QImage::defineIOHandler), thus providing the functionality in both  applications and WWW plugins from the same code.</table>  <p>This plugin supports transparency and scaling of the image, just likeGIFs in most WWW browsers.<br><EMBED align=middle src=test.png WIDTH=182 HEIGHT=138><EMBED align=middle src=test.png WIDTH=137
