Örnek 1 - ImagickDraw::setStrokeLineJoin() örneği

<?php
function setStrokeLineJoin($strokeColor, $fillColor, $backgroundColor) {

    $draw = new \ImagickDraw();
    $draw->setStrokeWidth(1);
    $draw->setStrokeColor($strokeColor);
    $draw->setFillColor($fillColor);

    $draw->setStrokeWidth(20);

    $offset = 220;

    $lineJoinStyle = [
        \Imagick::LINEJOIN_MITER,
        \Imagick::LINEJOIN_ROUND,
        \Imagick::LINEJOIN_BEVEL,
        ];

    for ($x = 0; $x < count($lineJoinStyle); $x++) {
        $draw->setStrokeLineJoin($lineJoinStyle[$x]);
        $points = [
            ['x' => 40 * 5, 'y' => 10 * 5 + $x * $offset],
            ['x' => 20 * 5, 'y' => 20 * 5 + $x * $offset],

For many (myself included) Rex's note maybe not be blatant enough. The constants are declared for the Imagick class only, so using them requires this syntax: Imagick::LINEJOIN_ constant



Here's an example oh how you might use it:



<?php

$img = new Imagick();

$img->newImage($width, $height, new ImagickPixel('transparent'));

$draw = new ImagickDraw();

$draw->setStrokeLineJoin(Imagick::LINEJOIN_ROUND);

?>



If you're not drawing polylines and are drawing simple lines, also see setStrokeLineCap
