the imagecreatetruecolor () function is used in php to create a new true color image. imagecreatetruecolor() retourne une ressource représentant une image noire. suivant votre version de php et de gd, cette fonction est définie ou non. de php version .. à la version ..x, cette fonction existe toujours si le module gd est chargé, mais l'appeler sans avoir gd d'installé fera que php lancera une erreur

i would recommend using imagecreate , not imagecreatetruecolor . when using imagecreate , the first colour you define will be the background colour that fills the entire canvas. this will usually be your "transparent" colour, however it is generally better (read: more efficient in the file) to do it this way: mai i moved the code to the top of the page and it works. i don't know why it does not work inside the html, possibly the header? humm, i had moved just the header to the top before but it still didn't work. i have to read more about the library anyways.
