PNG Support???

[Matthew Krusemark]

I am also interested in updating my app to support PNG.  Does anyone know of
an easy fix to update the *.sym files to support the PNG format?

Thank you in advance ... -matt

PNG is Portable Network Graphic, one of the newer format newer graphic
formats supported by GD in lieu of GIF.   Yes, that would be the image
format generated by mapserver.  For further info, see

Unisys holds the patent for GIF LZW compression...
PNG is supported by the newer versions of MS Internet Explorer and
NetScape Communicator and is legally unemcumbered..

To the best of my knowledge output of GIF or PNG is mutually excusive
depending
on the version of GD that you are compiling into mapserver.  Note that some
of
the old web browsers will not display PNG images.  Yes you can use PNG for
reference map and symbols/markers, but this will take a bit of work on your
part.
