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
$black = ImageColorAllocate($im, 0, 0, 0);
$white = ImageColorAllocate($im, 255, 255, 255);
$red = ImageColorAllocate($im, 255, 0, 0);
// set up array defining vertices of hexagonal bar, width depends on
'percent' parameter
$points=array(10,25,20,45,($x1+20),45,($x1+30),25, ($x1+20),5,20,5);
// draw polygon using array 'points' and colour red
imagefilledpolygon($im,$points,6,$red);
// write text on top of bar
imagestring($im,5,20,20,$percent.'%',$white);
// send the image to the browser
header("Content-type: image/png");
ImagePNG($im);
// tidy up
ImageDestroy($im);
?>
and an example of a page using the above code
<html>
<head>
<title>dynamic image</title>
<script type="text/javascript">
function graph(gaugeID)
{
var n=20;
var time=new Date();
var n=time.getSeconds();
n=Math.floor((n*100)/60);
document.getElementById(gaugeID).src='makepng.php? percent='+n;
var temp=setTimeout("VUgauge('gauge1')",1000);
}
</script>
</head>
<body onload="graph('placeholder');">
<img id="placeholder">
</body>
</html>
