Example #1 ImagickDraw::setVectorGraphics()

    $draw->setFillColor("red");
    $draw->circle(20, 20, 50, 50);

    //Get the drawing as a string
    $SVG = $draw->getVectorGraphics();
    
    //$svg is a string, and could be saved anywhere a string can be saved
    //Use the saved drawing to generate a new draw object
    $draw2 = new \ImagickDraw();
    //Apparently the SVG text is missing the root element. 
    $draw2->setVectorGraphics("<root>".$SVG."</root>");
    $imagick = new \Imagick();
    $imagick->newImage(200, 200, 'white');
