imagecreatefromgif
Description
imagecreatefromgif() returns an image identifier representing the image obtained from the given filename.
imagecreatefromgif() returns an empty string on failure. It also outputs an error message, which unfortunately displays as a broken link in a browser. To ease debugging the following example will produce an error GIF:
=ד 1. Example to handle an error during creation (courtesy vic@zymsys.com)
function LoadGif ($imgname) {$im = @imagecreatefromgif ($imgname); /* Attempt to open */ if (!$im) {/* See if it failed */ $im = imagecreate (150, 30); /* Create a blank image */ $bgc = imagecolorallocate ($im, 255, 255, 255); $tc = imagecolorallocate ($im, 0, 0, 0); imagefilledrectangle ($im, 0, 0, 150, 30, $bgc); /* Output an errmsg */ imagestring ($im, 1, 5, 5, "Error loading $imgname", $tc);} return $im;}
ע: Since all GIF support was removed from the GD library in version 1.6, this function is not available if you are using that version of the GD library.
