Hi,
I was searching for a raster functionality which works like 
VectorDataProjectionFilter for raster. I read the previous posts and 
encountered two suggestions. One was suggesting 
StreamingResampleImageFilter and the other one was suggesting 
ortho-rectification filter. The first one doesnt work at all (you give a 
transformation and it does nothing. One should think about this issue as 
well). 

I tried GenericRSResampleImageFilter and it takes ages to compute 
projection from the images projection to the exactly same projection 
(2000x2000 pixel image takes almost a minute. That is totally strange). 

What I am looking for is something like gdal_translate, which changes the 
projection from UTM to 4326. I find it really strange that Orfeo examples 
do not contain something like that. This is like the most basic thing one 
would expect from a remote sensing library.

It would be great, if someone can provide a working code so everybody can 
use in the future. If you guys believe orthorecitification filter does 
this, I am really looking forward to a working code for that as well 
because it requires the output size and scale.

All the best
Emre
