Oliver, Apologies for sending you down the wrong path. I don't follow the dev list, so I am not up on the latest feature opportunities (and pitfalls). My solutions appear to be aimed at things people have already figured out...

Though the bbox x/y ratio is exactly the same as the image x/y. I tried to request the same image directly in cgi, sadely I get exactly the same problem: image result in cgi: http://dev.camptocamp.com/~ochriste/cgi.png (as compared to the wms image http://dev.camptocamp.com/~ochriste/wms.png) this is the cgi request I used: /usr/lib/cgi-bin/mapserv -nh "QUERY_STRING=map=/var/www/veloland/private/veloland/veloland/wms/veloland.map&mode=map&LAYERS=MtblandRoutenNational&mapext=556960+220720+557600+221360&mapsize=256+256" > cgi.png I used exactly the same bbox and image size as the wms request: /wms?FORMAT=image%2Fpng&LAYERS=MtblandRoutenNational&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A21781&BBOX=556960,220720,557600,221360&WIDTH=256&HEIGHT=256 this is when using STYLE 1 20 END or PATTERN 1 20 END for the symbol when using GAP the dots are correctly shaped so I suspect the problem is within the interpretation of STYLE/PATTERN for the symbol generation ? 2010/1/12 Fawcett, David (MPCA) <david.fawc...@state.mn.us<mailto:david.fawc...@state.mn.us>> Are you requesting your image through a WMS and maybe getting a 'non-square pixel' effect? If you are using WMS, are the symbols round when you do a cgi request in mode=map or mode=tile? David.
