[[GifOverlay]] の PHP extension
誤って SF.NET に登録したので削除した。
- status を Inactive にした後、ceased

* 仕様 [#m28a2ee4]

** API [#b8dcf911]
 class GIFOverlay {
     function add($gif_data);  return true/false
     function output();        return $gif_data
 }

** 使用例 [#o1d2c53e]

 new $go = new GIFOverlay();
 $go->add(get_file_contents('background.gif'));
 $go->add(get_file_contents('avatar.gif'));
 $go->add(get_file_contents('item.gif'));
 echo $go->output; 

* SF.NET にプロジェクト登録してみた [#lbfafb0f]
 giflib/util/gifovly.c inspired me.
 gifovly.c is based begore GIF89 spec,
 no transparent, no animation.
 
 I think so good extend gifovlay.c
 to include GIF89 and GIF89a function,
 and provide php extension make us happy.
 
 ex)
  new $go = new GIFOverlay();
  $go->add(get_file_contents('background.gif'));
  $go->add(get_file_contents('avatar.gif'));
  $go->add(get_file_contents('item.gif'));
  echo $go->output(); // item.gif overlap avatar.gif overlap background.gif

無茶な英文だけど気持ちは伝わると信じてる。
