When you select to convert PDF files to ZIP in Calibre, the file created when un-zipped will create a new directory contain a number of PNG files. However what is interesting is the if the original PDF files contained 'watermarks' these will be removed in the PNG files and a separate PNG created containing only the watermark.

Does anyone anyone how this is achieved?
