Below given programs illustrate the GmagickDraw::ellipse() function in PHP:
Program 1 (Simple ellipse):

<?php
// Create a new Gmagick object
// https://media.geeksforgeeks.org/wp-content/uploads/geeksforgeeks-13.png
$gmagick = new Gmagick('geeksforgeeks.png');

// Create a GmagickDraw object
$draw = new GmagickDraw();

// Set the color
$draw->setFillColor('#0E0E0E');

// Function to draw rectangle
$draw->rectangle(-10, -10, 800, 400);

// Set the fill color
$draw->setFillColor('#3D99D4');

// Set the stroke width
$draw->setStrokeWidth(5);

// Draw a ellipse
$draw->ellipse(125, 70, 100, 50, 0, 360);

// Use of drawimage function
$gmagick->drawImage($draw);

// Display the output image
header("Content-Type: image/png");
echo $gmagick->getImageBlob();
?>

Output:

Program 2 (Stroked ellipse):

<?php
// Create a new Gmagick object
// https://media.geeksforgeeks.org/wp-content/uploads/geeksforgeeks-13.png
$gmagick = new Gmagick('geeksforgeeks.png');

// Create a GmagickDraw object
$draw = new GmagickDraw();

// Set the color
$draw->setFillColor('#0E0E0E');

// Function to draw rectangle
$draw->rectangle(-10, -10, 800, 400);

// Set the fill color
$draw->setFillColor('blue');

// Set the stroke color
$draw->setstrokecolor('green');

// Set the stroke width
$draw->setStrokeWidth(5);

// Draw a ellipse
$draw->ellipse(225, 70, 150, 50, 0, 360);

// Use of drawimage function
$gmagick->drawImage($draw);

// Display the output image
header("Content-Type: image/png");
echo $gmagick->getImageBlob();
?>

Output:
