Salut Viencent, 

Oui, je serais intéressé par une telle patche. J'ai essayé pix_alpha sur des 
pix_image, mais ça ne fonctionne pas toujours. On dirait que ça fonctionne 
mieux sur des vidéos que sur des images. Très bizarre. Sinon, je n'ai rien 
trouvé qui soit particulièrement "hot". Je mesure mes images avec PHP et 
j'envois tout ça avec netreceive. Je pourrais le faire en Python, mais c'est 
pour une conférence sur PHP que je vais donner... :-)
