Re:gd-png: fatal libpng error: zlib error in - 2007/12/20 23:57
ADSMANAGER n'est pas compatible avec la dernière installation de PHP5 qui introduit la notion de qualité dans la fonction imagepng.
Il faut patcher le composant comme suit dans le fichier adsmanager.php (les lignes ajoutées ou modifiées sont signalées par le commentaire //kmc_:
function createImageAndThumb($src_file,$image_name,$thumb_name,
$max_width,
$max_height,
$max_width_t,
$max_height_t,
$tag,
$path,
$orig_name)
{
global $mosConfig_absolute_path;
$types = array(
IMAGETYPE_JPEG => 'jpeg',
IMAGETYPE_GIF => 'gif',
IMAGETYPE_PNG => 'png'
);
ini_set('memory_limit', '20M');
$src_file = urldecode($src_file);
/*if (extension_loaded('exif'))
{
$type2 = exif_imagetype($src_file);
$types = array(
IMAGETYPE_JPEG => 'jpeg',
IMAGETYPE_GIF => 'gif',
IMAGETYPE_PNG => 'png'
);
$type = $types[$type2];
}
