Parameters: This function accepts six parameters as mentioned above and described below:
- $ox: It specifies the x-coordinate of the ellipse.
- $oy: It specifies the y-coordinate of the ellipse.
- $rx: It specifies the x-radius of the ellipse.
- $ry: It specifies the y-radius of the ellipse.

Below given programs illustrate the GmagickDraw::ellipse() function in PHP:
Program 1 (Simple ellipse):
<?php // Create a new Gmagick object $gmagick = new Gmagick('neveropen.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 $gmagick = new Gmagick('neveropen.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(); ?> |
