Below given programs illustrate the GmagickDraw::ellipse() function in PHP:
Program 1 (Simple ellipse):
<?php // Create a new Gmagick object // https://media.w3wiki.net/wp-content/uploads/w3wiki-13.png $gmagick = new Gmagick( 'w3wiki.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.w3wiki.net/wp-content/uploads/w3wiki-13.png $gmagick = new Gmagick( 'w3wiki.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(); ?> |
