I think this error has to do with processing the input imagery in
your LAYER, not the generation of the output image.<br>
How are you trying to classify your input data? What does your
LAYER object definition look like in your map file?<br>

Hi Jeff, <br>
<br>
Thanks again for your reply. I try to change but didn't work.
Do you think that have something to do with the
Format=image/png?? Just PNG don't reply 8 bits images?<br>
<br>
Also I have another raster image but that one works well. This
have 3 bands and values between 0 and 255. I'm using MapServer
version 6.2. <br>
<br>
Another idea? <br>
<br>
Best Regards,<br>
José Santos <br>
