This example shows the result from applying watermark when using non-transparent images like JPEGs, or using files with non-alpha transparency like GIFs.

Pay attention to the JPEG watermark: probably you all know it, but let me put these words of wisdom again – do not use JPEGs and plain flat colors. When the JPEG compression is applied, it tries to smoothen the image and this f*cks up the areas covered with flat color.

<?php
 
/**
* Include the main Asido class
*/
include('./../../class.asido.php');
 
/**
* Set the correct driver: this depends on your local environment
*/
asido::driver('gd');
 
/**
* Create an Asido_Image object and provide the name of the source
* image, and the name with which you want to save the file
*/
$i1 = asido::image('example.jpg', 'result_05.jpg');
 
/**
* Put a JPEG watermark image
*/
Asido::watermark($i1, 'watermark_05.jpg', ASIDO_WATERMARK_TOP_LEFT);
 
/**
* Put a GIF watermark image
*/
Asido::watermark($i1, 'watermark_05.gif', ASIDO_WATERMARK_BOTTOM_RIGHT);
 
/**
* Save the result
*/
$i1->save(ASIDO_OVERWRITE_ENABLED);
 
?>

Here you can see the source image, the watermark image, and the result:
