Unable to create non loop GIF image

[indapublic]

$gc->create($frames, $durations, LOOP);

define('LOOP', 0);

or

define('LOOP', FALSE);

But image still looped.

If you only want the animation to show once, set loop to 1. The README file says that setting loop to zero will give you an infinite loop.

<?

error_reporting(0);
set_time_limit(0);

define('LEFT', 130);
define('WIDTH', 360);
define('HEIGHT', 110);
define('SPEED', 100);
define('LOOP', 1);  //  Not working yet
global $frames, $durations;

$files = array(
        'http://img.page2images.com/ccimages/28/2c/mGOIqfym1vkiYiSN.png',

);

foreach ($files as $file) {
        $img = imagecreatetruecolor(WIDTH, HEIGHT);
        $im = imagecreatefrompng($file);
        $ims = getimagesize($file);
        imagecopy($img, $im, 0, 0, LEFT, 0, WIDTH, HEIGHT);
        ob_start();
        imagegif($img);
        $frames[] = ob_get_contents();
        $durations[] = SPEED;
        ob_end_clean();
}

include_once 'GifCreator.php';

$gc = new GifCreator();
$gc->create($frames, $durations, LOOP);

header('Content-type: image/gif');
echo $gc->getGif();

Your gif plays only once in Firefox and Opera. Which browser do you use when the gif loops?

[indapublic]

Opera 12.16 - Once
Firefox 28.0 - Once

Safari, MacOS Version 7.0.3 (9537.75.14) - Twice
Chrome 34.0.1847.116 - Twice
Opera 20.0.1387.91 - Twice

I think the patch below will fix the problem with "animate only once" and seems to work in both Firefox and Chrome.

diff --git a/src/GifCreator/GifCreator.php b/src/GifCreator/GifCreator.php

         }
     }

The main problem is that different browsers seem to have their own idea on how to interpret the loop counter so it's impossible to fix this in GifCreator. It seems possible to work well for loop values 0 (infinity) and 1 (play once), but for other values there will be differences between browsers.

GIF loop count	Chrome	Firefox
not set	1 play	1 play
0	infinite plays	infinite plays
1	2 plays	1 play
2	3 plays	2 plays
...	...	...
