Descrição

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

Aviso

Esta função não está documentada; apenas a lista de argumentos está disponível.

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.

Parâmetros

dashArray: array of floats

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();
?>
