i.pansharpen uses Python, not Bash. So it is not an integer math problem.

</div>
<div>However, you might try changing your input maps to float or DCELL. See if that changes things.</div>

I wonder if the script is doing integer division when it should be doing floating point division?<br>

<div>Hi all,<br>
<br>
I'm attempting to pansharpen some ikonos imagery using the i.pansharpen tool in Grass7 on windows 7 installed via OSGeo4W (r54756-478). The range for the sharpened red, green, and blue outputs are 0-30, which seems suspicious given the 16bit range of the input
bands. The command I used was:<br>
<br>
<a rel="nofollow" href="http://i.pansharpen.py/" target="_blank">i.pansharpen.py</a><span> </span>"sharpen=ihs" "ms3=ik_mss.4@eric" "ms2=ik_mss.3@eric" "ms1=ik_mss.2@eric" "pan=ik_pan@eric" "output_prefix=ik_ihs" <span> </span><br>
<br>
</div>
<div>The input bands are linked via r.external, would that matter?<br>
</div>
<div><br>
</div>
The output from my test area is below. Any assistance would be greatly appreciated.<span><image.png></span><br>
<br>
<br>
</div>
Thanks,<br>
