<br>
Thanks for posting the full source code.<br>
<br>
I manage to build it (after installing Boost), and got to the point<br>
where I needed one of the original TIFF images in order to<br>
test the code. Can you post one ?<br>
<br>
Looking at the source code, the only thing that I found suspicious<br>
is the use of NumericTraits::max() in the definition of the default<br>
pixel value for the resampler.<br>
<br>
These intensity rescaling shouldn't be happening with the<br>
classes that you are using.<br>
<br>
There may be something particular about your input TIFF<br>
images....<br>
<br>
<br>
Regards,<br>
<br>
<br>
Luis<br>
