Thanks for the compliment on my function. I have since improved upon
it...see below.
I can do the exact same thing as you and get results, but what I can't do is
show the image within an HTML table. I think it is something to do with the
header line, but I dont know how to get around it. I've tried just calling
the function like I have in the code below. I've also tried calling the
function inside of <img> command. Both ways dont work.
Check out the code if you can and let me know if you seen anything that I am
doing wrong. Thanks
<?php
function makepie($slice, $total){
$height = 150;
$width = 150;
$im = ImageCreate($width, $height);
$bck = ImageColorAllocate($im, 255, 255, 255);
$black = ImageColorAllocate($im, 0, 0, 0);
$white = ImageColorAllocate($im, 255, 255, 255);
$red = ImageColorAllocate($im, 255, 0, 0);
$blue = ImageColorAllocate($im, 0, 0, 255);
//imagefilledellipse($im, 75, 75, 125, 125, $red);
//imageellipse($im, 75, 75, 125, 125, $black);
//Making the Slice
$pieslice = (($slice / $total) * 360) + 315;
imagefilledarc($im, 75, 75, 125, 125, 315, $pieslice, $blue,
IMG_ARC_PIE);
imagefilledarc($im, 75, 75, 125, 125, 315, $pieslice, $black,
IMG_ARC_NOFILL);
imagefilledarc($im, 75, 75, 125, 125, $pieslice, 315, $red,
IMG_ARC_PIE);
imagefilledarc($im, 75, 75, 125, 125, $pieslice, 315, $black,
IMG_ARC_NOFILL);
//Return
Header("Content-type: image/png");
ImagePNG($im);
}
echo "<table border='1' cellpadding='0' cellspacing='0'
style='border-collapse: collapse' bordercolor='#111111' width='200'
bgcolor='#FFD1A4'>
<tr>
<td width='100%' colspan='2' align='center'>This is a
test<br>".makepie(20,200)."</td>
</tr>
</table>";
?>
