<p class=MsoNormal style='margin-bottom:12.0pt'>hi David<br>
<br>
Im requesting the image through wms indeed.<br>
Though the bbox x/y ratio is exactly the same as the image x/y.<br>
I tried to request the same image directly in cgi, sadely I get exactly the
same problem:<br>
<br>
image result in cgi: <a href="http://dev.camptocamp.com/~ochriste/cgi.png">http://dev.camptocamp.com/~ochriste/cgi.png</a><br>
<br>
(as compared to the wms image <a
href="http://dev.camptocamp.com/~ochriste/wms.png">http://dev.camptocamp.com/~ochriste/wms.png</a>)<br>
<br>
this is the cgi request I used:<br>
/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<br>
<br>
I used exactly the same bbox and image size as the wms request:<br>
<br>
/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<br>
<br>
this is when using STYLE 1 20 END or PATTERN 1 20 END for the symbol<br>
<br>
when using GAP the dots are correctly shaped<br>
<br>
so I suspect the problem is within the interpretation of STYLE/PATTERN for the
symbol generation ?<br>

try with GAP 20 instead of STYLE 1 20 END (which is deprecated btw, use PATTERN
now)<br>
