GifOverlap の PHP extension specAPIclass GIFOverlap { function add($gif_data); return true/false function output(); return $gif_data } usagenew $go = new GIFOverlap(); $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.NETregistrationgiflib/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 GIF89a function, , mofidy overlay to overlap routine, and provide php extension make us happy. ex) new $go = new GIFOverlap(); $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 My poor english, But I beleave heartful communication. relative |
