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

−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
