$image = \think\Image::open(request()->file('image'));

// 返回图片的宽度
$width = $image->width();
// 返回图片的高度
$height = $image->height();
// 返回图片的类型
$type = $image->type();
// 返回图片的mime类型
$mime = $image->mime();
// 返回图片的尺寸数组 0 图片宽度 1 图片高度
$size = $image->size();

裁剪图片

$image->crop(300, 300)->save(ROOT_PATH.'public/static/image/crop.png');
