note 43637 added to function.imagecreatefromgif

Ok, here's an interesting tidbit. I wouldn't call it a bug, exactly, but it did make for an interesting workaround the GD/GIF situation. using PHP Version 4.3.4/GD bundled (2.0.15 compatible), I am able to use imagecreatefromgif() to load an image into GD, although I am not able to use imagegif() to display it. I'm not sure *why* this is, but the practical aspect is that if you need to do dynamic changes to a loaded image and want to display it to the browser (for example, a dynamic thumbnailer), you can load a gif image using imagecreatefromgif(), and then display it using a different image type! I recommend using PNG, since JPG is a lossy format. For example, given some image at $location: <?php $test = strtolower($location); if(strpos($test, ".jpg") !== false || strpos($test, ".jpeg") !== false) { $this->OriginalImage = imagecreatefromjpeg($location); $ImageType = "jpg"; header("Content-type: image/jpeg"); } // transform GIFs into PNGs else if(strpos($test, ".gif") !== false) { $OriginalImage = imagecreatefromgif($location); $ImageType = "png"; header("Content-type: image/png"); } else if(strpos($test, ".png") !== false) { $OriginalImage = imagecreatefrompng($location); $ImageType = "png"; header("Content-type: image/png"); } /* * * Do some image manipulation, stored for this example as $OutputImage * */ switch ($ImageType) { case "jpg": imagejpeg($OutputImage); break; case "png": imagepng($OutputImage); break; default: break; } ?> Now, as I said, I'm not sure if this is an oversight/bug or not, but if you can get it working, it's a great workaround for GD's lack of GIF processing. ---- Manual Page -- http://www.php.net/manual/en/function.imagecreatefromgif.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+43637 Delete -- http://master.php.net/manage/user-notes.php?action=delete+43637&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+43637&report=yes Search -- http://master.php.net/manage/user-notes.php
