Hello Steve..
I can recreate the wrong output with your sample-map. I added an projection PROJECTION 'init=epsg:31466' END #PROJECTION Now I can fire my GetMap-Request: http://localhost/cgi-bin_ms5.4.2/mapserv.exe?LAYERS=too_small,too_large,just_right&SRS=EPSG:31466&FORMAT=image/png&WIDTH=200&HEIGHT=200&SERVICE=WMS&VERSION=1.1.1&STYLES=&BBOX=0,0,200,200&map=C:/umn_maps/test/symbol_problem.map&REQUEST=GetMap  I found out that when I using FORMAT=image/gif the output looks nice: http://localhost/cgi-bin_ms5.4.2/mapserv.exe?LAYERS=too_small,too_large,just_right&SRS=EPSG:31466&FORMAT=image/gif&WIDTH=200&HEIGHT=200&SERVICE=WMS&VERSION=1.1.1&STYLES=&BBOX=0,0,200,200&map=C:/umn_maps/test/symbol_problem.map&REQUEST=GetMap  I also tryed to use a gif-symbol, but no change, same problem. Do you using the Mapservers own CGI-Request or WMS-Request? thanks, regards, Daniel |

I've been using shp2img. Just tried on another box with 5.4.2 with the attached result (verbatim mapfile I posted earlier).
Are you using the experimental PNG support by chance? Wouldn't think that would have an impact but I think that links MapServer against libpng. GD also links against libpng and perhaps there is confusion there if the versions are different?
