Below given programs illustrate the GmagickDraw::arc() function in PHP:
Used Image: 
Program 1 (Drawing arc from scratch):
PHP
<?php // Create a new Gmagick object $gmagick = new Gmagick('neveropen.png'); // Create a GmagickDraw object $draw = new GmagickDraw(); // Set the color $draw->setFillColor('white'); // Function to draw rectangle $draw->rectangle(0, 0, 800, 400); // Set the fill color $draw->setFillColor('white'); // Set the stroke color $draw->setstrokecolor('black'); // Set the stroke width $draw->setStrokeWidth(5); // Mark a arc $draw->arc(60, -60, 460, 170, 0, 200); // Use of drawimage function $gmagick->drawImage($draw); // Display the output image header("Content-Type: image/png"); echo $gmagick->getImageBlob(); ?> |
Output:
Program 2 (Drawing arc on a image):
php
<?php // Create a new Gmagick object $gmagick = new Gmagick('neveropen.png'); // Create a GmagickDraw object $draw = new GmagickDraw(); // Set the fill color $draw->setFillColor('red'); // Set the stroke color $draw->setstrokecolor('green'); // Set the stroke width $draw->setStrokeWidth(5); // Mark a arc $draw->arc(160, -60, 360, 170, 50, 200); // Use of drawimage function $gmagick->drawImage($draw); // Display the output image header("Content-Type: image/png"); echo $gmagick->getImageBlob(); ?> |
