Asido is a feature-rich image processing class for PHP that fits to any environment like GD2, Magick Wand and Image Magick. It supports both PHP4 & PHP5 (newer versions support only PHP5).

An example of adding a watermark to an image:

<?php
include(’./../../asido/dev/class.asido.php’);
asido::driver(’gd’);
$i1 = asido::image(
      ‘the-source-image.jpg’,
      ‘filename-with-which-you-want-to-save-the-result.png’
);
asido::watermark($i1, ‘put-the-watermark-image-here.png’);

?>

It is really simple and clear.

Asido can:

• resize
• watermark
