Watermark Gravity

Asido

This example demonstrates how to use the watermark gravity. There are nine locations at which you can put the watermark (except when using the tile watermark), and this example puts a watermark on every one of these locations.

<?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_01.jpg');
 
/**
* Put a watermark image on every possible gravity location
*/
$watermark = 'watermark_01.png';
Asido::watermark($i1, $watermark, ASIDO_WATERMARK_TOP_LEFT);
Asido::watermark($i1, $watermark, ASIDO_WATERMARK_TOP_CENTER);
Asido::watermark($i1, $watermark, ASIDO_WATERMARK_TOP_RIGHT);
Asido::watermark($i1, $watermark, ASIDO_WATERMARK_MIDDLE_LEFT);
Asido::watermark($i1, $watermark, ASIDO_WATERMARK_MIDDLE_CENTER);
Asido::watermark($i1, $watermark, ASIDO_WATERMARK_MIDDLE_RIGHT);
Asido::watermark($i1, $watermark, ASIDO_WATERMARK_BOTTOM_LEFT);
Asido::watermark($i1, $watermark, ASIDO_WATERMARK_BOTTOM_CENTER);
Asido::watermark($i1, $watermark, 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:

   hi!

   how i can i integrate it with my file upload?
   I want to upload files then process it with Asido..
   I seem have a difficulty knowing the image source if it’s not yet uploaded…

   thanks!

   Hi,
   you wrote ti yourself – “…upload files then process it with Asido…” – so you first have to be sure the files are uploaded to the server and that they are available, and then process them with Asido as with any other image you have access to on the server.

   Was wondering if there was a way to use Asido to add user inputted text to an existing image at predefined locations?

   @Rewt: currently, Asido does not support such features.

   What is the best way to display the results of an asido object? I see a method called “__write()”, but using it like
   “@image->__write();” generates an error….

   __write() is a private(protected) method and it can not be used outside the boundaries of the class; if you want to see the results you have to save the asido_image by calling asido_image::save()
