Create a watermark version of the first NumPages pages of a file. A watermark version is PDF file, but the whole content is added as pictures in an adjustable resolution. Furthermore, the picture is annotated by a watermark text going diagonal across each page.

There is no way to increase the quality or remove the watermark text completely afterwards.
