[Gdal-dev] ECW "Rotational Coefficients Ignored"

[Dan Greve]

Does this mean the input images need to be warped to North-Up?  What are the 
rotational coefficients ignored?  I'm trying to convert a NITF into an ECW 
with gdal_translate and no special switches.  I get the same error for 
JP2ECW and ECW.

Here's the source nitf info
