Re: [Geotools-gt2-users] How to reproject images the right way?

Hello Daniele

Thanks for the feedback!

First of all, I know about the memory issue when not using JAI, not 
complaining. But things should ideally always work when using JAI, right..?

OK, here we go:

Yes, pretty much that.

OK, now it works for me too, both with and without JAI! (guess it was 
one of your corrections?)

Now it also works in both cases, great. Strange is that it takes a much 
much longer time with this MrSID file, as compared with the equivalent 
ECW sample. OK, ECW is much faster, but I guess it shouldn't take that 
long since the image is not really that big.

A quick look tells me that some other tests here also seem to be working 
now. What were the issues that you found when reprojecting SAD69?

Let's see what your other results show!

Cheers
Milton
