如何设置新7版本的边距？ 我想删除页面的边距，设置为0。在版本6中，我将它们设置为新的mPDF（但现在我不知道怎么可能
在我使用的6上：
$pdf = new \mPDF('utf-8', 'A4'.($orientation == 'L' ? '-L' : ''), '', '', $margin_left, $margin_right, $margin_top, $margin_bottom, 0, 0);
现在？
谢谢

mPDF 7构造函数的签名为
CoreVideo您需要传递带有适当键的值数组，其边距为SIGSEGV Attempted to dereference null pointer.

，\Mpdf\Mpdf::__construct([array $config = []])
，margin_left，margin_right，margin_top和{ {1}}。
整个代码将是
margin_bottom所有这些和其他构造函数$ config键都写在mPDF constructor documentation page上。
