optimize() public static method

This function calls up to four external programs, which must be installed and available in the $PATH: * SVGO * image_optim * picopt * ImageOptim Note that these are executed using PHP’s exec command, so there may be security implications.
public static optimize ( string $path, integer $svgo, integer $image_optim, integer $picopt, integer $imageOptim )
$path string The path to the file or directory that should be optimized.
$svgo integer The number of times to optimize using SVGO.
$image_optim integer The number of times to optimize using image_optim.
$picopt integer The number of times to optimize using picopt.
$imageOptim integer The number of times to optimize using ImageOptim.
