[MS4W-Users] Geotif - WMS using MS4W Zoo

[TC Haddad]

Hi Morten

Can you report the version of gdal that you used to generate the tif?

Only asking because last week I had a similar problem with a single band
tif that I created using gdal_translate and I was using (I believe) v.2.4.2
at the command line (MS4W 4.0.1).

The person that I passed the tif to could not access the pixel values using
Mapserver, which I found strange because the image displayed correctly.  In
that case they solved it by using another program to open and re-save a new
tif. After that I stopped thinking about it (I thought it was my error),
but maybe there is something else going on?
