Hi Tim,<br>
I have a RGB-ised satellite image we are digitising from, but our
(oldish) software displays it as a red image.<br>
I fiddled around using tiffinfo on other images that display correctly
with this software, and noticed the difference in the Planar
Configuration. (Which also explains why we only see the red)<br>
Our Windows based R2V package allowed the conversion (which then
displays correctly in our Linux package), but I am looking for
something to do this conversion via a Linux bash script - and to make
minimum or no other changes to the Tiff image.<br>
<br>
Regards,<br>
Zoltan<br>

<pre wrap="">Hi
Do you mean you want to copy from a palletted tiff to an e.g. Single band greyscale tif? Or three bands each representing R, B, G? Bearing in mind that you will lose the colour info, you could do this using gdal_translate.
Regards
Tim

Subject: [OSGeo Africa] Converting TIFF image planes
Sent: Nov 12, 2009 10:35 AM
Hi,
I've had a look at some of the Linux tiff tools (eg tiffcp) but cannot
find a way to command-line convert an RGB tiff image from separate image
planes, to a single image plane.
Does anyone have any pointers, please?
Thanks & regards,
Zoltan
