Description (last modified by )
There is a problem with creating a lossless JPEG2000 image with JP2KAK (kakadu) from an unsigned int image : the output image has an +32768 offset. This offset seems to be constant.
The test image is an unsigned int TIFF image (see attachment).
I tried different GDAL versions : 1.7.3, 1.8 and 1.8.1
Kakadu version is 6.4.1 (latest).
Platform is Linux Red Hat 5 64 bits.
To reproduce the bug :
gdal_translate -of JP2KAK -co QUALITY=100 input.tif out_gdal_translate.jp2
Using kakadu tools there is no problem :
kdu_compress -i input.tif -o out_kdu_compress.jp2 Creversible=yes Clayers=16
(Creversible is used instead of QUALITY=100)
