Used Image:

Program 1 (Drawing arc from scratch):

PHP

<?php

// 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(); 
?>
