• (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
