A bit more information about ImagJ, from the documentation:<br>
<br>
"16-bit and 32-bit grayscale images are not directly displayable
on computer monitors, which typically can show only 256 shades of
gray. Therefore, the data are mapped to 8-bits by windowing. The
window defines the range of gray values that are displayed: values
below the window are made black, while values above the window are
white. The window is defined by minimum and maximum values that
can be modified using <i>Image>Adjust>Brightness/Contrast</i>."<br>
<br>
Is this the sort of function you are looking for?<br>
</blockquote>
Not really, but thanks for the information.<br>
In fact, we use a 16bit camera to acquire some signal that we
process with Scilab. We don't really need to directly look at the
unprocessed image.<br>
We don't want to throw away information while processing the data.<br>
Moreover, we need to be able to compare the relative intensity
between to different images which mean we cannot adjust image
settings independently.<br>

I already played with ImageMagick but I don't know how to use it
to convert in a format scilab can import.<br>
As for libTIFF, I am currently playing with it in an attempt to
write my own import function for scilab.<br>

Gimp (at least the version I have on Fedora13) does not support
16bit.<br>
