저는 Imagick를 사용하여 그래픽을 생성하고 있습니다.
ImagickDraw::setStrokeAlpha 메소드를 사용하여 그래픽의 줄을 투명하게 만들고 싶습니다.
하지만, 이 메소드의 사용법이 잘 이해되지 않습니다.
ImagickDraw::setStrokeAlpha 메소드는 어떤 파라미터를 받으며,
그리고 어떤 효과를 발생시킬까요?

그리고, 이 메소드를 사용하여 투명한 줄을 그리는 방법을 알려주세요.

    ImagickDraw::setStrokeAlpha 메소드는 ImagickDraw 객체에 투명도(alpha)를 설정하는 메소드입니다. 이 메소드는 float 타입의 파라미터를 하나 받습니다.

    이 메소드는 그래픽의 줄에 투명도를 적용하여 투명한 줄을 그릴 수 있도록 합니다.

    투명한 줄을 그리는 방법은 다음과 같습니다.

    ```php
    $draw = new ImagickDraw();
    $draw->setStrokeAlpha(0.5); // 투명도 0.5를 설정합니다.
    $draw->setStrokeColor('black'); // 줄 색상을 검정으로 설정합니다.
    $draw->setFillColor('black'); // 채우기 색상을 검정으로 설정합니다.
    $draw->rectangle(10, 10, 50, 50); // 사각형을 그립니다.
    $imagick = new Imagick();
    $imagick->newImage(100, 100, 'white');
    $imagick->setImageFormat('png');
    $imagick->drawImage($draw);
    $imagick->setImageAlphaChannel(Imagick::ALPHACHANNEL_SET);
