JxrEncApp [options]...

-i input.bmp/tif/hdr
    Input image file name bmp: <=8bpc, BGR tif: >=8bpc, RGB hdr: 24bppRGBE only

-o output.jxr
    Output JPEG XR file name

-q quality
    [0.0 - 1.0) Default = 1.0, lossless

or quantization
    [1 - 255] Default = 1, lossless

-c format
    Required to define uncompressed source pixel format 0: 24bppBGR 1: 1bppBlackWhite 2: 8bppGray 3: 16bppGray 4: 16bppGrayFixedPoint 5: 16bppGrayHalf 7: 32bppGrayFixedPoint 8: 32bppGrayFloat 9: 24bppRGB

-d chroma sub-sampling
    0: Y-only 1: YCoCg 4:2:0 2: YCoCg 4:2:2 3: YCoCg 4:4:4 (default)

    (if not set is 4:4:4 for quality >= 0.5 or 4:2:0 for quality < 0.5)

-l overlapping
    0: No overlapping 1: One level overlapping (default) 2: Two level overlapping

    (if not set is One for quality > 0.4 or Two for quality <= 0.4)

-f  Turn off frequency order bit stream (to spatial)

-p  Turn off progressive mode (to sequential)

-t  Display timing information

-v  Display verbose encoder information

-V tile_wd0 [tile_wd1 ... ]
    Macro block columns per tile

-H tile_ht0 [tile_ht1 ... ]
    Macro block rows per tile

-U num_v_tiles num_h_tiles
    Vertical & horizontal tile count for uniform tiling

-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: JxrEncApp -i input.bmp -o output.jxr -q 10
