- -b Black/White
-
Applies to 1bpp black/white images 0: 0 = black (default) 1: 0 = white
- -a alpha channel format
-
Required for any pixel format with an alpha channel 2: Planar alpha (default) 3: Interleaved alpha Other: Reserved, do not use
- -Q quantization for alpha

[1 - 255] Default = 1, lossless
- -F trimmed flexbits
-
[0 - 15] 0: no trimming (default) 15: trim all
- -s skip subbands
-
0: All subbands included (default) 1: Skip flexbits 2: Skip highpass 3: Skip highpass & lowpass (DC only)
Eg: ./debian/tmp/usr/bin/JxrEncApp -i input.bmp -o output.jxr -q 0.9
