This is simple script to demonstrate the capabilities of PHP with the GD library, which provides a lot of image functions that can be useful in many applications. GD provides a rich set of functions. For a complete list of these functions, check the PHP manual.
<?php
<?php
header('Content-Type: image/png');
// Text to be converted to image
$text = 'Hello World';
// Font to use, give accessible path from script
$font = './arial.ttf';
// Convert HTML entities into ISO-8859-1
$text = html_entity_decode($text,ENT_NOQUOTES, "ISO-8859-1");
// Create the image
$im = imagecreatetruecolor(160, 160);
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
// Create some colors
imagefilledrectangle($im, 0, 0, 160, 80, $white);
// Add the text
imagettftext($im, 12, 0, 20, 20, $black, $font, $out);
imagepng($im);
imagedestroy($im);
exit;
?>
GD can also be used to create and manipulate image files in a variety of different image formats, including GIF, PNG, JPEG, WBMP, and XPM.

GD can also be used to create and manipulate image files in a variety of different image formats, including GIF, PNG, JPEG, WBMP, and XPM.
Limitations:
- Though GD supports Unicode text inputs, it doesn't support complex text rendering
- Complex Text Rendering is required for properly displaying many language texts, such as the Arabic alphabet and scripts of the Brahmic family, which includes Tamil and many other Indic scripts.
