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;
?>
