Example 1. Example to handle an error during creation
<?php
function LoadWBMP($imgname)
{
$im = @imagecreatefromwbmp($imgname); /* Attempt to open */
if (!$im) { /* See if it failed */
$im = imagecreatetruecolor (20, 20); /* Create a blank image */
$bgc = imagecolorallocate($im, 255, 255, 255);
$tc = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 10, 10, $bgc);
/* Output an errmsg */
imagestring($im, 1, 5, 5, "Error loading $imgname", $tc);
}
return $im;
}
?>
