Essaye de supprimer le if

Bonjour,
J'essaye d'utiliser la version 2 d'imagick pour manipuler des images et la documentation est quasi inexistante.
Je souhaiterai redimensionner un gif animé.
Le code suivant redimensionne correctement la premiere image mais pas les autres images :
[php]
//Iterator is set on first image
$picture->setFirstIterator();

//used to resize image or in case of an animated gif, the first image
$picture->scaleImage($width, $height);

//resize every other image of an animated gif
if(1 < $picture->getNumberImages()){
while($picture->hasNextImage()){
$picture->nextImage();
$picture->scaleImage($width * 0.55, $height);
}
}
[/php]

Un coup de main serait le bienvenu. Merci d'avance.
