//Set the fontsize $draw ->setfontsize(72);
// Function to draw circle $draw ->circle(250, 250, 100, 150);
$gmagick = new Gmagick();
$gmagick ->newImage(500, 500, 'White' );
$gmagick ->setImageFormat( "png" );
$gmagick ->drawImage( $draw );
// Using getfontsize() function print_r( $draw ->getfontsize());
?> |
Output:
72
Program 2:
<?php // Create a GmagickDraw object $draw = new GmagickDraw();
// Set the color $draw ->setFillColor( 'Green' );

// Function to draw line 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 the color $draw ->setFillColor( 'Black' );
//set Font Size $draw ->setFontSize(25);
// Use of 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" );
