</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">ok i am working with mapserver and a nodejs project and so i am calling mapserver like so.<br>
<br>
mapserv -nh "/getPreviewImg.map&mode=map&mapext='+req.params.extent+'&filename='+req.params.imgname+'&projection=3158"<br>
<br>
the issue is that mapserver dose not support projection based run time substitution and so i was wondering if that is possible to add and how hard it would be (maybe i could to it myself etc if pointed in right direction because i have no experience with mapserver's
src)<br>
<br>
map file example thats what i want to replace<br>
<br>
PROJECTION<br>
"init=epsg:%projection%"<br>
END<br>
<br>
or perhaps even this then i could build what ever<br>
<br>
PROJECTION<br>
%projection%<br>
END<o:p></o:p></p>
