[mapserver-users] raster layer

Mon Aug 26 09:40:09 EDT 2002

I am not sure where is the mistake, but I see different map extent in your
map file and WLD file. Also I would reccomend to use TIFF 256 color file
instead of JPEG format (there are the problems with color depth in the MS)
uin the start. Then you may experimet with true color JPEG pictures.
