[mapserver-users] adding ecw support

[Jackson, John]

Here's the output of gdalinfo for the ecw file... Could it be the lack of coordinate system info?

Your MAP contents looks fine to me.

Did you run ldconfig after the libecw/gdal compilation ?

Sometimes when I upload some raster files to my production server, they are somehow corrupted. Please check if you can
see test.ecw with ER Viewer or other applications, and if this is your case too, check the byte length of the local and the remote
files.

Maybe you should recompile Mapserver. I don't remember if this must be done, but I thing you don't need it.

Debug 5 produces:
[Mon Apr 25 12:00:04 2011].97972 msDrawRasterLayerLow(ortho): entering.
[Mon Apr 25 12:00:04 2011].98406 drawEPP(): Image handling error. EPPL7 support is not available.
[Mon Apr 25 12:00:04 2011].98414 msDrawRaster(): Image handling error. Unrecognized or unsupported image format
[Mon Apr 25 12:00:04 2011].98421 msDrawMap(): Image handling error. Failed to draw layer named 'ortho'.

relevant section from map file is pretty straightforward:

        LAYER
                NAME "ortho"
                STATUS on
                TYPE RASTER
                DATA "/home/ecw/test.ecw"
        END

Try setting DEBUG 5 and CONFIG MS_ERRORFILE '/var/www/error.log' into the MAP section to see what does
Mapserver throws.

Also, can you post the MAP file contents ?

Quick question:

I've compiled libecw3.3 and gdal... now gdalinfo --formats shows the ECW format, but mapserver still won't produce a map with an ecw file.

Do I need to recompile mapserver also?

(I'm running 5.65 on a Fedora 13 box if that helps)

Thanks
