[Gdal-dev] Save GeoTiff

[Ayman Kamal]

I attach the file "fltinfo.txt" that contains the
fltinfo for two images, the first one is a colored 256
color image, the second is the same as the first but
converted to gray scale.

The colored one causes the problem, but the gray scale
doesn't

The program that complained about the colored image
file is "3DEM"
