    Dynamic Image?

    Who knows how this is done:

    404 Not Found
    http://www.danasoft.com/vipersig.jpg


    As you can see the signature is dynamical, it uses gdlib I assume and php.
    But does anybody have any code for this? Please help me find this, I
    allready searched alot, but can't seem to find anything yet...

    Regards, Cybex

      ImageMagick would work well for this, if it's installed on your server.
      If you have Telnet or SSH:
      whereis ImageMagick
      will tell you where it is.

          PHP to generate a horizontal bar graphic in a PNG file when called with a
          URL parameter 'precent'

          makepng.php
          <?php
          // read url parameter 'percent'
          $percent=$_GET["percent"];
          // calculate size of bar
          $x1=floor(460*( $percent/100));

          // build image
          $im = ImageCreate(500 , 50);

          // set colours, first colour created is background
          $black = ImageColorAlloc ate($im, 0, 0, 0);
          $white = ImageColorAlloc ate($im, 255, 255, 255);
          $red = ImageColorAlloc ate($im, 255, 0, 0);

          // set up array defining vertices of hexagonal bar, width depends on
          'percent' parameter
          $points=array(1 0,25,20,45,($x1 +20),45,($x1+30 ),25,($x1+20),5 ,20,5);

          // draw polygon using array 'points' and colour red
          imagefilledpoly gon($im,$points ,6,$red);

          // write text on top of bar
          imagestring($im ,5,20,20,$perce nt.'%',$white);

          // send the image to the browser
          header("Content-type: image/png");
          ImagePNG($im);

          // tidy up
          ImageDestroy($i m);
          ?>

          and an example of a page using the above code

          <html>
          <head>
          <title>dynami c image</title>
          <script type="text/javascript">
          function graph(gaugeID)
          {
          var n=20;
          var time=new Date();
          var n=time.getSecon ds();
          n=Math.floor((n *100)/60);

          document.getEle mentById(gaugeI D).src='makepng .php?percent='+ n;
          var temp=setTimeout ("VUgauge('gaug e1')",1000);
          }
          </script>
          </head>
          <body onload="graph(' placeholder');" >
          <img id="placeholder ">
          </body>
          </html>
