# Problem I. 360. (November 2014)

I. 360. In the advertisements nowadays one can see not only washing powders, concerts or tabloid newspapers, but also museums and educational institutions. In this exercise you should design a KöMaL advertisement that can be placed e.g. on the public transportation vehicles. In order to present your realistic plan, you should put an advertisement on the troli.jpg image (source: http://iho.hu/img/galery/130523-iktroli.jpg).

However, many people freely use images downloaded from the Internet, without specifying the source. Hence, watermarks are often used to identify the creator of the image. Watermarks can contain texts or graphics. The example below falls into the first category:

You should create a watermark for our journal that could be placed on the images of komal.hu having size at least $\displaystyle 800\times 600$ pixels. You should put your watermark on any of the images on the page http://www.komal.hu/hirek/2004-09/imo2004/beszamolo.h.shtml. The watermark should be clearly visible but should not obscure the original content. You can use any freely available tools to complete your task.

The description of your solution (i360.pdf) and your images should be submitted and uploaded in a single compressed file (i360.zip) also containing the name and version number of the software used, and a sufficiently accurate explanation to reproduce your advertisement and watermark on the given image.
