// Set the width and height of the image $draw -> setStrokeWidth (7);  
// Set font size $draw -> setfontsize (72);  
// Function for drawing a circle $draw -> circle (250, 250, 100, 150); $gmagick = new Gmagick(); $gmagick -> newImage (500, 500, ’White’ ); $gmagick -> setImageFormat ( "png" ); $gmagick -> drawImage ( $draw );  
// Using the getfontsize() function print_r ( $draw -> getfontsize()); ?>

// Set color $draw -> setFillColor ( ’Green’ );  
// Set the width and height of the image $draw -> setStrokeWidth (1);  
// Line drawing function for ( $x = 0; $x < 40; $x ++) { $draw -> line (rand (0, 100), rand (0, 60), rand (0, 500), rand (0, 500)); $draw -> line (rand (0, 100), rand (0, 60), rand (0, 500), rand (0, 500)); $draw -> line (rand (0, 100), rand (0, 60), rand (0, 500), rand (0, 500)); $draw -> line (rand (0, 100), rand (0, 60), rand (0, 500), rand (0, 500)); } $gmagick = new Gmagick(); $gmagick -> newImage (500, 500, ’White’ ); $gmagick -> setImageFormat ( "png" );  
// Set color $draw -> setFillColor ( ’Black’ );  
// set font size $draw -> setFontSize (25);  
// Using the drawimage function $gmagick -> drawImage ( $draw ); $gmagick -> annotateImage ( $draw , 5, 120, 0, ’GeeksforGeeks: A computer science portal’ );  
// Display the output image header ( "Content-Type: image / png" ); echo $gmagick -> getImageBlob(); ?>
