JPEG2000 Driver doesn't write 16bit images

Reported by: warmerdam Owned by: dron
Priority: high Milestone:
Component: GDAL_Raster Version: unspecified
Severity: normal Keywords:



The JasPer driver seems to read 16bit images properly, but doesn't write them
properly.  It seems to produce an 8bit result, and input values larger than
256 just "wrap" instead of being clipped. 

Could you implement 16bit write support at some point?  This is low priority.

Strange... My 16-bit samples are encoded and decoded fine. Could you show me
problematical dataset?

I have upgraded to JasPer 1.700.2.uuid (from the 1.600.0.uuid) and the
problem is resolved.  16bit works just fine.
