Description
When converting Int16 data to JP2KAK with the -co "QUALITY=100" option, strange artifacts are created in the nodata values and also in teh image data. Using the conversion without the lossless option everything works (but the image has a near black seam).
Attached to this ticket you will find two examples, one with the quality parameter, one without. The commands were the following:
gdal_translate -ot Int16 -of JP2KAK hb738_0000.dt4.04.tif hb738_0000.dt4.04.jp2
gdal_translate -ot Int16 -of JP2KAK -co "QUALITY=100" hb738_0000.dt4.04.tif hb738_0000.dt4.04_qual100.jp2
The originating tiff (Mars elevation) will also be attached.
