ECW Support

[Bart van den Eijnden (OSGIS)]

I have used ECW files on Windows with MS4W in the past. Which version of 
MS4W are you using?

Are you able to read the ECW file with gdalinfo (install fwtools from 
www.maptools.org/fwtools)? If so, can you post the output of gdalinfo as 
well as your LAYER definition in the MAP file?

Are you using Mapserver CGI or PHP/Mapscript to render the ECW?

How large is the ECW file?

Also, try to put debugging on in Mapserver 
(http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?DebuggingMapserver) and 
optionally use CONFIG CPL_DEBUG "ON" at the MAP level in your map file 
to get GDAL to output debug info.

Best regards,
Bart
