[gdal-dev] Is it a big thing to change ECW to support 16-bit imagery?

[mohwawang]

Hi all,

When I used gdal_translate to convert a 16-bit QuickBird image to a ECW JPEG2000 compressed NITF image I got a 

Warning: ECW only supports Byte pixel data type, ignoring request for UInt16.

Is it a big job (for example, change the algorithm of compression in ECW) or not so big a job to have ECW also support 16-bit imagery? Thanks.

Best Regards,

Mo
