Compression ratio off when exporting 16-bit multiband JPG2000

cradacrada Global Mapper UserPosts: 8
When exporting a 16-bit one band JPG2000 even a 100 target compression gives the result of a 2 or 4 target compression.
Even using this highest setting of 100, I get a file that is about 1/4 of the size of the GeoTiff and have very high quality.

    Hello,

    I suggest that you contact Blue Marble Support directly via emal (geohelp@bluemarblegeo.com) to address this issue. Please include a detailed description of your workflow, including screen captures of any options screens you used, and sample input data that can be used to reproduce the problem. Thank you.
