This function requires at least 3 points. The following code fails when there are only two points left in the array:
<?php
$im = new Imagick ();
$points = array (array ('x' => 10, 'y' => 10), array ('x' => 20, 'y' => 10), array ('x' => 30, 'y' => 40), array ('x' => 40, 'y' => 20), array ('x' => 50, 'y' => 60));
$n = 0;
while (!empty ($points))
{
$im->newImage (64, 64, "white");
$draw = new ImagickDraw ();
$draw->setFillColor ("none");
$draw->setStrokeWidth (4);
$draw->setStrokeColor ("black");
$draw->setStrokeOpacity (0.9);
$draw->setStrokeAntiAlias (true);
$draw->bezier ($points);
$im->drawImage ($draw);
$im->writeImage ("IMG_$n.png");
$draw->destroy ();
$im->destroy ();
echo count ($points) . ", $n: <img src=\"IMG_$n.png\"><br>";
$n++;
array_shift ($points);
}
?>

How to use:
<?php
$width = 200;
$height = 200;
$border = 2;
$img = new Imagick();
$img->newImage( $width, $height, new ImagickPixel( 'transparent' ) );
$draw = new ImagickDraw();
$draw->setStrokeColor( new ImagickPixel( 'black' ) );
$draw->setStrokeWidth( 2 );
$draw->setFillColor( new ImagickPixel( 'transparent' ) );
// will fail in an obscure manner if the input data is invalid
$points = array
(
array( 'x' => 0, 'y' => 200 ),
array( 'x' => 0, 'y' => 0 ),
array( 'x' => 200, 'y' => 200 ),
array( 'x' => 200, 'y' => 0 )
);
$draw->bezier($points);
$img->drawImage( $draw );
$img->setImageFormat( "png" );
header( "Content-Type: image/png" );
echo $img;
?>
