Re: [Geotools-gt2-users] Writing a GeoTIFF with CRS

[Daniele R. <dan...@gm...>]

Hi Greg,
I have investigated on your issue and I think I have found the problem. I
have opened a JIRA for this -> [1]
I have fixed it. I'm just finishing to test the changes and then I will
committ it on both 2.6.x and trunk.
In the mean time, I can send you the updated jar so you can check if that
works fine.

Let me know.
Regards,
Daniele
