[gdal-dev] Re: GDAL encounters problem with very small files

[Matthieu Rigal]

Hi Frank,

Thanks for your response.
I made the error of mixing one gdal_utility question and a Python-GDAL binding 
question.

The problem I am encountering with gdal_translate and gdalinfo with these very 
little files only happens when I am working on very small images. Else, it is 
working well.
And I use these utilities from the shell, so it should have nothing to do with 
Python.
But as I told you, I have only the version 1.4.2 installed here...

On the other hand I have problems with the Python piece of code I have copied, 
so I just wanted to know if I forgot something in these simple data copying 
code. I will look for that, thanks.

So for the first problem, I will try it again  on other configurations, with 
GDAL 1.5.3 or 1.6 beta and maybe with different libtiff versions...
If you still have other ideas, tell me ;)

Best regards,
Matthieu
