[Gdal-dev] gdal_translate: Floating point exception when trying to convert NSIF image (JPG)

[Reiner Beck]

Hello,

I get a floating point exception when I try to convert a JPG compressed
NSIF image. The message
    Warning 1: Image with 0 bits per sample will not be interpreted
properly.
can be seen.

> gdal_translate test.nsf test.tif
   Warning 1: Image with 0 bits per sample will not be interpreted properly.
   Input file size is 936, 749
   0Floating point exception

However, I am able to display the image with a different piece of
software correctly.

This happens with gdal from CVS (gdal-cvs-2006.11.07) on a Suse Linux
10.1 (kernel 2.6.16.21-0.25-smp).

Any ideas?

Cheers
Reiner
