- -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
