hi David Im requesting the image through wms indeed. 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> > 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. > > > > *From:* mapserver-users-boun...@lists.osgeo.org [mailto: > mapserver-users-boun...@lists.osgeo.org] *On Behalf Of *Oliver Christen > *Sent:* Tuesday, January 12, 2010 9:31 AM > *To:* thomas bonfort > > *Cc:* mapserver-users@lists.osgeo.org > *Subject:* Re: [mapserver-users] symbol circle (ellipse) rendered not > round but oval > > > > Hi Thomas :) > > > > thanks for the answer, but sadely it didnt solve my problem: > > > > here are a few tests I did: > > > > using GAP 20 gave me really weird result: > > http://dev.camptocamp.com/~ochriste/tilecache6_gap_20.png<http://dev.camptocamp.com/%7Eochriste/tilecache6_gap_20.png> > > > > using PATTERN 1 22 END gave me better result, but the dot are still > slightly oval: > > http://dev.camptocamp.com/~ochriste/tilecache7_pattern.png<http://dev.camptocamp.com/%7Eochriste/tilecache7_pattern.png> > > > > I wondered if the visual effect may have come from the fact im pilling up > two circle one over the other, but even when trying to display only the > outer or inner circles, the circle are still slightly off: > > http://dev.camptocamp.com/~ochriste/tilecache4_outercircle.png<http://dev.camptocamp.com/%7Eochriste/tilecache4_outercircle.png> > > http://dev.camptocamp.com/~ochriste/tilecache5_innercircle.png<http://dev.camptocamp.com/%7Eochriste/tilecache5_innercircle.png> > > (both at once > http://dev.camptocamp.com/~ochriste/tilecache3_bothcircle.png<http://dev.camptocamp.com/%7Eochriste/tilecache3_bothcircle.png> > ) > > > > any other idea? ^_^ > > ----- Original Message ----- > > *From:* thomas bonfort <thomas.bonf...@gmail.com> > > *To:* Oliver Christen <oliver.chris...@camptocamp.com> > > *Cc:* mapserver-users@lists.osgeo.org > > *Sent:* Tuesday, January 12, 2010 3:18 PM > > *Subject:* Re: [mapserver-users] symbol circle (ellipse) rendered not > round but oval > > > > hi Oliver :) > > try with GAP 20 instead of STYLE 1 20 END (which is deprecated btw, use > PATTERN now) > > cheers, > thomas > > On Tue, Jan 12, 2010 at 15:04, Oliver Christen < > oliver.chris...@camptocamp.com> wrote: > > hello > > I have a weird problem with symbology. > Im rendering a line with dots, but the dots are not round but slightly > oval, see image > http://dev.camptocamp.com/~ochriste/tilecache.png<http://dev.camptocamp.com/%7Eochriste/tilecache.png> > > Any idea what could be the cause ? > > Here is my symbol definition: > > SYMBOL > NAME "linie-gepunkt10" > TYPE ELLIPSE > POINTS > 1 1 > END > STYLE > 1 20 > END > FILLED TRUE > END > > and my layer's class definition: > > CLASS > EXPRESSION "3" > MAXSCALEDENOM 200001 > STYLE > SYMBOL "linie-gepunkt10" > SIZE 10 > COLOR 102 51 0 > END > STYLE > SYMBOL "linie-gepunkt10" > SIZE 8 > COLOR 204 102 0 > END > END > > and the map outputformat: > > OUTPUTFORMAT > NAME png > DRIVER "AGG/PNG" > MIMETYPE "image/png" > IMAGEMODE RGBA > EXTENSION "png" > FORMATOPTION "INTERLACE=OFF" > END > _______________________________________________ > mapserver-users mailing list > mapserver-users@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/mapserver-users > > > >
