$thumb = imagecreatetruecolor($width, $height);

Post by: satine88 on June 18, 2010, 07:41:32 PM: I deleted all the pictures, then I
create new every time I had this message :

Code: [Select]
Warning: imagesavealpha (): Supplied argument Is Not a valid Image resource in / Homez.93/fondecra/www/icones/includes/image_utils.p hp on line 75
Code:

Quote
$types = array(1 => "gif", 2 => "jpeg", 3 => "png");
  if ($convert_options['convert_gd2']) {
    imagealphablending($thumb, false);
   imagesavealpha($thumb, true);
   $thumb = imagecreatetruecolor($width, $height);
  }
  else {
   $thumb = imagecreate($width, $height);
  }

Thanks
