resize image

[margherite]

Io l'ho fatto così:

//
// RIDIMENSIONA IMMAGINE
//
function resizeJPG($jpgFile, $width, $jpgNewFile)
{
// Get new dimensions
list($width_orig, $height_orig) = getimagesize($jpgFile);
$height = (int) (($width / $width_orig) * $height_orig);

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($jpgFile);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

// Output
imagejpeg($image_p, $jpgNewFile, 60);
}
