You could also intercept the constructor to enable the internal upscaling for "rounder" corners at lower scales (which would be counter-intuitive for the user to set):

	public function __construct(SettingsContainerInterface $options, QRMatrix $matrix){
		$options->drawCircularModules = true;

		parent::__construct($options, $matrix);
	}

protected function module(int $x, int $y, int $M_TYPE): void {

$x1 = ($x * $this->scale);
$y1 = ($y * $this->scale);
$x2 = (($x + 1) * $this->scale);
$y2 = (($y + 1) * $this->scale);

$rectsize = ($this->scale / 2);

/**

* 7 # 3
