The example should clarify, what I need: I have a template for company documents, which has some text, lines and graphics (external pdf or png) in its footer. Now I want to make the header be less visible than the rest of the page. Surely I can set a color of the text to gray and edit the image, but is there some other way? best regards Jan See page 204, section 8.5 of the metafun book loadfigure gracht.mp number 1 scaled .5 ; addto currentpicture also (currentpicture softened .8) shifted (bbwidth(currentpicture)+.5cm,0) ; (this example draws the picture alongside its softened copy.)

I wanted to say that Hans already implemented some code to add transparency (or even transparent masks) to bitmap images, but I'm still not sure how to use that code. However, drawing a transparent white rectangle over the bitmap graphic would definitely be the easiest approach if you don't need to see though the image.
