Hi All,
=20
In order to dynamically create images in various formats, I downloaded
mapserver 3.7 binaries for windows (to use the new OUTPUTFORMAT =
declaration)
from the dmsolutions website (I also would like to use mapscript).
It works fine for some formats if I only ask for vector data but I get a
white image if I ask for raster data (all declared in my map file). In =
fact,
I would like to subset and convert raster data using the WMS capability =
of
Mapserver.
=20
Does anyone have an idea of what's going wrong ? I put a part of my =
mapfile
at the bottom of this message.
=20
I made some tests by requesting maps of vector data and I had several
problems with the following output formats :
Here is my query :

&REQUEST=3DGetMap&VERSION=3D1.1.0&LAYERS=3Dparcels&FORMAT=3Decw
parcels is a shapefile

ECW : the file is created in the mapserver temp directory but not send =
to
the browser. I get this error message :
Content-type: application/vnd.ogc.se_xml

JP2 : I would like to use wavelet compressed images (most probably ecw =
as
there are more readers available for this format) and I am interested in =
the
JPEG2000 format (JP2KAK). I use the GDAL library for windows provided =
with
OpenEV and I can use gdal_translate.exe without any problem to read and
write jp2 files (-of JP2KAK). With mapserver I get this error message...
=20
loadOutputFormat(): General error message. OUTPUTFORMAT clause =
references
driver GDAL/JP2KAK, but this driver isn't configured
=20
And my last question is related to the doc entitled MapFile Reference -
MapServer 3.7. It is written that the "EXTENSION" keyword can be used =
but it
is not recognized by the build of Mapserver I downloaded. Does it work =
under
more recent releases ?
=20
I am sorry about all these questions. A few months ago, I was in an =
other
company and working with mapserver on a linux computer but here, as I =
want
to use ecw format, I have to work on a windows computer.....
=20
Best regards,
Paul
