  • ImagickDraw::pathStart()

    (PECL imagick 2.0.0)

    Declares the start of a path drawing list

    说明

    ImagickDraw::pathStart(void): bool
    Warning

    本函数还未编写文档,仅有参数列表。

    Declares the start of a path drawing list which is terminated by a matching DrawPathFinish()command. All other DrawPath commands must be enclosed between a and a DrawPathFinish()command. This is because path drawing commands are subordinate commands and they do not function by themselves.

    返回值

    没有返回值。

    范例

    Example #1 ImagickDraw::pathStart()

    <?php
    function pathStart($strokeColor, $fillColor, $backgroundColor) {
        $draw = new \ImagickDraw();
        $draw->setStrokeOpacity(1);
        $draw->setStrokeColor($strokeColor);
        $draw->setFillColor($fillColor);
        $draw->setStrokeWidth(2);
        $draw->setFontSize(72);
        $draw->pathStart();
        $draw->pathMoveToAbsolute(50, 50);
        $draw->pathLineToAbsolute(100, 50);
        $draw->pathLineToRelative(0, 50);
        $draw->pathLineToHorizontalRelative(-50);
        $draw->pathFinish();
        $draw->pathStart();
        $draw->pathMoveToAbsolute(50, 50);
        $draw->pathMoveToRelative(300, 0);
        $draw->pathLineToRelative(50, 0);
        $draw->pathLineToVerticalRelative(50);
        $draw->pathLineToHorizontalAbsolute(350);
        $draw->pathclose();
        $draw->pathFinish();
        $draw->pathStart();
        $draw->pathMoveToAbsolute(50, 300);
        $draw->pathCurveToAbsolute(50, 300, 100, 200, 300, 300);
        $draw->pathLineToVerticalAbsolute(350);
        $draw->pathFinish();
        $imagick = new \Imagick();
        $imagick->newImage(500, 500, $backgroundColor);
        $imagick->setImageFormat("png");
        $imagick->drawImage($draw);
        header("Content-Type: image/png");
        echo $imagick->getImageBlob();
