    float $width,
    float $height
): bool

警告

本函数还未编写文档，仅有参数列表。

Indicates that subsequent commands up to a DrawPopPattern() command comprise the definition of a named pattern. The pattern space is assigned top left corner coordinates, a width and height, and becomes its own drawing space. Anything which can be drawn may be used in a pattern definition. Named patterns may be used as stroke or brush definitions.

参数

pattern_id: the pattern Id
x: x coordinate of the top-left corner
y: y coordinate of the top-left corner
width: width of the pattern
height: height of the pattern

返回值

成功时返回 true，或者在失败时返回 false。

    $draw->setStrokeOpacity(1);
    $draw->setStrokeColor($strokeColor);
    $draw->setFillColor($fillColor);

    $draw->setStrokeWidth(1);

    $draw->pushPattern("MyFirstPattern", 0, 0, 50, 50);
    for ($x = 0; $x < 50; $x += 10) {
        for ($y = 0; $y < 50; $y += 5) {
            $positionX = $x + (($y / 5) % 5);
            $draw->rectangle($positionX, $y, $positionX + 5, $y + 5);
        }
    }
    $draw->popPattern();

    $draw->setFillOpacity(0);
    $draw->rectangle(100, 100, 400, 400);
    $draw->setFillOpacity(1);

    $draw->setFillOpacity(1);

    $draw->push();
    $draw->setFillPatternURL('#MyFirstPattern');
    $draw->setFillColor('yellow');
    $draw->rectangle(100, 100, 400, 400);
    $draw->pop();

    $imagick = new \Imagick();
    $imagick->newImage(500, 500, $backgroundColor);
    $imagick->setImageFormat("png");

    $imagick->drawImage($draw);

    header("Content-Type: image/png");
