Creating Scanlines

BlitzPlus Forums/BlitzPlus Programming/Creating Scanlines

I'm affraid I allready know the answer, but is it possible to
create a scanline filter? (see picture below).
This is a 50% opaque filter done in Photoshop.
This filter is probably even harder to realize than an
odd/even scanline.

I'm trying to simulate an arcade screen/tv set feeling for my
new game Sokorat. This way it looks way better than a
sharp monitor in my opinion.

I found a topic on this subject before but maybe someone
did figuere it out by now.
Otherwise. Blitz team... plase make a plug-in/dll for this in
one of the next B+ versions. Is shouldn't be that hard I
guess.
