Consider image sample below. I'm including it using \includegraphics and I have linked it to an url using \href.
What I would like is to have it in the pdf file in such a way that the mouse would only allow you to follow the link when passing over the grey zone and not through the white background.
I'm using a png file with no background but with no success...
Does someone know how to do this?
Thank you so much in advance!
