[mapserver-users] Raster layer problem

Hello,

Here are my quick thoughts:

- remove all projection objects from your mapfile
- remove all layers from your mapfile except the one raster/tif layer
- use the ogrinfo utility, which is included in MS4W, to get the extents 
of your tif file (http://www.gdal.org/ogrinfo.html)
- use those extents in your mapfile's EXTENT parameter
- test your mapfile with the shp2img utility, which is also included in 
MS4W (http://www.mapserver.org/utilities/shp2img.html)
- note that MS4W is already configured for the following IMAGEPATH and 
IMAGEURL parameters:

     IMAGEPATH "/ms4w/tmp/ms_tmp/"
     IMAGEURL "/ms_tmp/"

(the above imagepath value assumes that you have MS4W installed at a 
root of a drive...if you used the setup.exe installer you might have 
installed it elsewhere, so that imagepath value might be different)

Hope those quick thoughts help.

-jeff
