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
