Hi,
this is pretty shallow, but maybe someone knows a way: for one of my
presentation, every slide has a (different) picture as background. The title is
typeset within a narrow colored frame which extends across the entire slide. Is
there any way to make the background picture show through the letters of the
title, i.e. make the letters transparent within the colored frame? I thought of
metapost’s infill, but it appears that this only adds a background color, not
real transparency.
Hope the question is clear enough - just in case someone has a suggestion; my
life doesn’t depend on it!
