I am having some problems generating images with GD. I am using GD 1.6.2
and trying to create a .png image. I know it works. I have created just a
generic graphic without trying to put variables into it and am hoping
someone can help me on this one. Here is some code snippet
// here is my gd.php file to create the image
<?
Header ( "Content-Type: image/png" );
$im = ImageCreate ( 10, 200 );
$red = ImageColorAllocate ( $im, 255, 0, 0 );
$white = ImageColorAllocate ( $im , 255, 255, 255 );
$blue = ImageColorAllocate ( $im , 0 , 0 , 255 );
$gray = ImageColorAllocate ( $im , 0xC0, 0xC0 , 0xC0 );
ImageFill ( $im , 0 , 0 , $gray );
ImageFilledRectangle ( $im , 0 ,$bluehg, 3, 200, $blue );
ImageFilledRectangle ( $im , 6, $redhg, 10, 200, $red );
// write the image
ImagePNG( $im );
// clean up the mess
ImageDestroy($im);
?>
// here is the function that I use to determine the attributes of the image
// create a function to call gd.php
function graphic($blueval, $redval)
{
$pctrd = round($blueval*100, 1);
$pctbl = round($redval*100, 1);
$blueval = ($blueval * 200);
$redval = ($redval * 200);
echo "<table>
<tr>
<td
align=\"center\">$pctbl%</td>
<td><img
src=\"gd.php?bluehg=$blueval&redhg=$redval\" height=\"100\" /></td>
<td
align=\"center\">$pctrd</td>
</tr>
</table>";
}
On the page I get a broken image. If I view the source I see the image is
being called with params.
Any help would be appreciated.
Thanks.
Chad
