    (PECL imagick 2, PECL imagick 3)

    ImagickDraw::pathCurveToQuadraticBezierAbsolute — Draws a quadratic Bezier curve

    说明

    publicImagickDraw::pathCurveToQuadraticBezierAbsolute(
        float$x1,
        float$y1,
        float$x,
        float$y
    ): bool
    警告

    本函数还未编写文档，仅有参数列表。

    Draws a quadratic Bezier curve from the current point to (x,y) using (x1,y1) as the control point using absolute coordinates. At the end of the command, the new current point becomes the final (x,y) coordinate pair used in the polybezier.

    参数

    x1

    x coordinate of the control point

    y1

    y coordinate of the control point

    x

    x coordinate of the end point

    y

    y coordinate of the end point

    返回值

    没有返回值。

    示例

    示例 #1 ImagickDraw::pathCurveToQuadraticBezierAbsolute() example

    <?php
    function pathCurveToQuadraticBezierAbsolute($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(50,250);

    // This specifies a quadratic bezier curve with the current position as the start
