Hi Jukka,
from what I can see in

this dates back to almost 20 years ago when SetGCPs() was initially
implemented. And at that time, PAM didn't exist yet in GDAL :-)
Please create a ticket about (and mention SetGeo
Hi,
I tried to add ground control points into a TIFF file with gdal_edit. I do not
want to touch the TIFF so I used the read-only option and supposed that gcp
would be written into .aux.xml file but that did not happen. Instead I got a
message

Hi,
I have been searching an easy way to change the interpretion of 4-channel
images between RGBA and RGB+undefined. Wouldn't if be useful to make gdal_edit
to support also changing the TIFFTAG_EXTRASAMPLES metadata? Or do we have some
other easy way for performing that task?

Yes, that looks good.

be more about suggestion in making the documentation more usable.

Hi,
I noticed that when I tried to add one TIFFTAG metadata item with
gdal_edit.py by using the -mo option it wrote my new metadata and wiped away
all the existing TIFFTAG metadata. For the desired result I had to give the
whole list of metadata tags with repeated -mo options. Is this intentional
Hello,
This utility program is very useful to change georeferencing of a raster
without having to decompress and recompress it. It is a lot faster and
the quality is not changed.
I think it would deserve to be an official GDAL 1.10 command, not just a
Python sample.
