Hi<br>
<br>
I spent much time searching for reason why my raster does not appear
in WMS layer.<br>
My raster is in EPSG:31255 projection<br>

<br>
When I convert the rasterfile to epsg:3857 using gdalwarp and
request Layer in the same crs<small><small>
&CRS=EPSG:31255&</small></small> I get the correct
getMap request. If I switch to <small><small>&CRS=EPSG:31255&</small></small>
to force mapserver to reproject I got the same white/empty image.<br>
<br>
Could somebody help me?<br>
I can send you a sample of raster on email address.<br>
