Below given programs illustrate the GmagickDraw::bezier() function in PHP:
Program 1: Simple Bezier Curve
<?php
$gmagick = new Gmagick( 'geeksforgeeks.png' );
$draw = new GmagickDraw();
$draw ->setFillColor( '#0E0E0E' );
$draw ->rectangle(-10, -10, 800, 400);
$draw ->setFillColor( '#3D99D4' );
$draw ->setStrokeWidth(5);
$draw ->bezier([
[ 'x' => 10, 'y' => 10],
[ 'x' => 0, 'y' => 0],
[ 'x' => 620, 'y' => 0],
[ 'x' => 550, 'y' => 170],
]);
$gmagick ->drawImage( $draw );
header( "Content-Type: image/png" );
echo $gmagick ->getImageBlob();
?>

Output:
Program 2: Bezier curve with stroke and fill
<?php
$gmagick = new Gmagick( 'geeksforgeeks.png' );
$draw = new GmagickDraw();
$draw ->setFillColor( '#0E0E0E' );
$draw ->rectangle(-10, -10, 800, 400);
$draw ->setFillColor( 'yellow' );
$draw ->setstrokecolor( 'purple' );
$draw ->setStrokeWidth(5);
$draw ->bezier([
[ 'x' => 10, 'y' => 10],
[ 'x' => 0, 'y' => 150],
[ 'x' => 620, 'y' => 0],
[ 'x' => 550, 'y' => 170],
]);
$gmagick ->drawImage( $draw );
header( "Content-Type: image/png" );
echo $gmagick ->getImageBlob();
?>
