[Mapserver-users] symbol SIZE in CLASS - misleading

[Havard Tveite]

When rendering point and polygon symbols, I have discovered
that the SIZE parameter of a CLASS gives the rendered vertical
size of the symbol in pixels - 1.
This is unexpected behaviour and not documented(?). It means
that people who want to have full control of their symbols
appearance will be very confused.

What are the reasons for this strange behaviour (apart from
indexing in C)?

I hope that the semantics of the SIZE parameter can be
changed so that it gives the exact vertical size of the
symbol in pixels. The problem is, of course with legacy
symbol sets and mapfiles, but since the changes that are
made in Mapserver 4 are already significant...
