Hi all,<br>
<br>
I'm trying to use MrSid-layers in my map, but they are not displayed.<br>
<br>
The MrSid-Dataset is readable for GDAL, because gdalinfo gives a
reasonable feedback<br>

displayed without problems.<br>

Here is the config of mapserver:<br>
<i><small><small>./mapserv -v<br>

SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT

<br>
MrSid is configured in GDAL as Brent Fraser wrote in the list:
<a class="moz-txt-link-freetext" href="http://xserve.flids.com/pipermail/gdal-dev/2004-August/006783.html">http://xserve.flids.com/pipermail/gdal-dev/2004-August/006783.html</a><br>
except that for SUSE Linux the MRSID_LIB in nmake.opt might have no
effect; I think it can be set in LD_LIBRARY_PATH<br>
<br>
This is the log when the map is built:<br>
<i><small><small>...<br>
[Tue Dec 7 16:43:51 2004].508426 msDrawRasterLayerLow(mrsid): entering.<br>

dst=485,464,5,5<br>
...</small></small></i><br>
<br>
Curious that there is no msDrawGDAL()-message for the MrSid-Dataset.<br>
<br>
Any suggestions?<br>
<br>
Thanks for your help.<br>
