Yup, it's possible, for example:
http://maps1.dnr.state.mn.us/cgi-bin/mapserv70?map=/usr/local/mapserver/apps/test/barter/test.map=map
The mapfile is below...
MAP
NAME 'barter'
SIZE 256 256
IMAGECOLOR 255 255 255
EXTENT 0 0 255 255
SYMBOL
NAME 'circle'
TYPE ELLIPSE
Is it possible for me to have a layer that places a symbol at the centre of the
generated tile and text at a fixed position from the bottom?
My aim is to make a single WMS tile call to get back a map image with marker at
centre and text at bottom.
