LateX – Transparent Watermark Image

If you want to add a watermark image to your LaTeX document, you can achieve it easily using three packages: graphicx, tikz and eso-pic:

Graphicx package allows to load images into documents. If you want to add transparency to your image, you need also to use tikz package. Tikz is used for producing vector graphics from a geometric/algebraic description, but is also allows to play with opacity levels.

Eso-pic package provides hooks to inserts the images on one or more pages as a background (in other words – a watermark).






I have attached a final result as PDF, so you can see the output: PDF with semi-opaqued watermark.
