There are many sites that publish content that is mainly based on photos that they have been taken or acquired from somebody that took them.

Unfortunately there are also unscrupulous people that steal the photos from those sites and publish in other sites as if they where the ones that originally obtained the pictures, thus gaining undeserved credit and audience.

One way to prevent stealing sites to gain undue credit, is to put a mark of origin in the photos that is hard to remove.

This class provides a solution for processing picture by placing a transparent watermark that not only identifies the real origin of the picture, it can also make it difficult to remove such mark with the usual image processing tools.
