[Gdal-dev] problem of gdal_translate 1.1.9 and 1.2.1 with multiplebands

[Xiaodong Zhang]

Thanks Frank,

Yes you are right, I have to use gdal_translate -b 1 -b 2 -b 3 ... to spectrally
subset an image, but it only works for version 1.2.1 but not for 1.1.9. Version
1.1.9 produces only one band regardless. Both ways of sending '-b' arguments,
i.e., -b 1,2,3,4 or -b 1 -b 2 -b 3 -b 3, work for earlier version, 1.1.8.

On aother note, are there any significant changes for versions later than 1.1.8.
In another email, I reported that our program using gdal api crashes for both
version 1.1.9 and 1.2.1, while it works perfectly for version 1.1.8.

Thanks again.
Xiaodong
