When two line segments meet at a sharp angle and miter joins have been specified for 'lineJoin', it is possible for the miter to extend far beyond the thickness of the line stroking the path. The miterLimit' imposes a limit on the ratio of the miter length to the 'lineWidth'.

Example #1 ImagickDraw::setStrokeMiterLimit()
<?phpfunction setStrokeMiterLimit($strokeColor, $fillColor, $backgroundColor) { $draw = new \ImagickDraw(); $draw->setStrokeColor($strokeColor); $draw->setStrokeOpacity(0.6); $draw->setFillColor($fillColor); $draw->setStrokeWidth(10); $yOffset = 100; $draw->setStrokeLineJoin(\Imagick::LINEJOIN_MITER); for ($y = 0; $y < 3; $y++) { $draw->setStrokeMiterLimit(40 * $y); $points = [ ['x' => 22 * 3, 'y' => 15 * 4 + $y * $yOffset], ['x' => 20 * 3, 'y' => 20 * 4 + $y * $yOffset], ['x' => 70 * 5, 'y' => 45 * 4 + $y * $yOffset], ]; $draw->polygon($points); } $image = new \Imagick(); $image->newImage(500, 500, $backgroundColor); $image->setImageFormat("png"); $image->drawImage($draw); $image->setImageType(\Imagick::IMGTYPE_PALETTE); $image->setImageCompressionQuality(100); $image->stripImage(); header("Content-Type: image/png"); echo $image->getImageBlob();}?>
