ImagickDraw::setStrokeDashArray

(PECL imagick 2, PECL imagick 3)

ImagickDraw::setStrokeDashArray — Specifies the pattern of dashes and gaps used to stroke paths

说明

public ImagickDraw::setStrokeDashArray(array $dashArray): bool

警告

本函数还未编写文档，仅有参数列表。

Specifies the pattern of dashes and gaps used to stroke paths. The strokeDashArray represents an array of numbers that specify the lengths of alternating dashes and gaps in pixels. If an odd number of values is provided, then the list of values is repeated to yield an even number of values. To remove an existing dash array, pass a zero number_elements argument and null dash_array. A typical strokeDashArray_ array might contain the members 5 3 2.

参数

dashArray: array of floats

返回值

成功时返回 true。

    $draw->setStrokeDashArray([10, 10]);
    $draw->rectangle(100, 50, 225, 175);

    $draw->setStrokeDashArray([20, 5, 20, 5, 5, 5,]);

To remove the dash and switch back to solid line, provide an array with a null value in it for $dashArray.

->setStrokeDashArray( [null] );

Example:

<?php
$base_image = new Imagick('example.png');
$rect = new ImagickDraw();
$rect->setFillColor(new ImagickPixel("#EEEEEE"));
$rect->setFillOpacity(0);
$rect->setStrokeColor(new ImagickPixel("#FF0000"));
$rect->setStrokeDashArray(array(5,5,5));
$rect->rectangle(10, 10, 100, 100);
$base_image->drawImage($rect);

header('Content-type: image/png');
echo $base_image->getImage();
exit();
?>
