-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

-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

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
