Thanks Paul,
Unfortunately no luck. Setting "transparency alpha" makes the
transparent part around the symbols completely white :)
It seems to be the exact same problem as Jim Clack encountered [1], who
never found a solution either. Makes me think its actually a bug and not
intended behavior. Perhaps I'll start digging through the code.
Cheers,
Ben

I have a very simple mapfile to display a bunch of points as PNG
symbols.
Problem is that the transparent part of the symbols are clobbering
each other with the background color (see attached image). What I
would like to see is a whole wack of merged together symbols when
they are overlapping without the background color coming through.
Any thoughts as to what could be causing this?
