Okay bestie, this is the JxrEncApp(1) manual, filed under User Commands 📖✨

✨ NAME ✨

JxrEncApp - the JPEG XR Encoder Utility 🦋

✨ DESCRIPTION ✨

JPEG XR Encoder Utility Copyright 2013 Microsoft Corporation - All Rights Reserved 💅

Here's how you call it, no cap 🫶

./debian/tmp/usr/bin/JxrEncApp [options]...

• -i input.bmp/pnm/tif/hdr — this is your input image file name 📸 bmp takes <=8bpc BGR, pnm and tif take >=8bpc RGB, and hdr is 32bppRGBE only
• -o output.jxr — where your shiny new JPEG XR file gets saved 🌈
• -q quality — a value from [0.0 - 1.0). Default is 1.0, which is lossless 💖
• or quantization — the other way to set it, [1 - 255]. Default is 1, also lossless ✨
• -c format — this one is required 🚨 It tells the encoder what pixel format your uncompressed source is:
  • 0: 24bppBGR
  • 1: 1bppBlackWhite
  • 2: 8bppGray
  • 3: 16bppGray
  • 4: 16bppGrayFixedPoint
  • 5: 16bppGrayHalf
  • 7: 32bppGrayFixedPoint
  • 8: 32bppGrayFloat
  • 9: 24bppRGB
  • 10: 48bppRGB
  • 11: 48bppRGBFixedPoint
  • 12: 48bppRGBHalf
  • 14: 96bppRGBFixedPoint
  • 15: 128bppRGBFloat
  • 16: 32bppRGBE
  • 17: 32bppCMYK
  • 18: 64bppCMYK
  • 22: 32bppBGRA
  • 23: 64bppRGBA
  • 24: 64bppRGBAFixedPoint
  • 25: 64bppRGBAHalf
  • 27: 128bppRGBAFixedPoint
  • 28: 128bppRGBAFloat
  • 29: 16bppBGR555
  • 30: 16bppBGR565
  • 31: 32bppBGR101010
  • 32: 40bppCMYKA
  • 33: 80bppCMYKA
  • 34: 32bppBGR
• -d chroma sub-sampling — pick your chroma vibe 🎨
  • 0: Y-only
  • 1: YCoCg 4:2:0
  • 2: YCoCg 4:2:2
  • 3: YCoCg 4:4:4 (default)

If you don't set it, you get 4:4:4 when quality is >= 0.5, or 4:2:0 when quality is < 0.5.

• -l overlapping — how much overlapping you want 🧚
  • 0: No overlapping
  • 1: One level overlapping (default)
  • 2: Two level overlapping

If you don't set it, you get One when quality is >= 0.5, or Two when quality is < 0.5.

• -f — switches off the frequency order bit stream, so it goes spatial instead 🌸
• -p — switches off progressive mode, so it goes sequential 🍓
• -t — shows timing info ⏱️
• -v — shows the verbose encoder info, for the nerds 🤓💜
• -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 and horizontal tile count for uniform tiling 🌷
• -b Black/White — this only applies to 1bpp black and white images 🖤🤍
  • 0: 0 = black (default)
  • 1: 0 = white
• -a alpha channel format — required for any pixel format that has 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 means no trimming (default), and 15 trims everything ✂️
• -s skip subbands — choose which subbands to skip 🦋
  • 0: All subbands included (default)
  • 1: Skip flexbits
  • 2: Skip highpass
  • 3: Skip highpass & lowpass (DC only)

Eg, here's a sample run that's giving main character energy 👑

./debian/tmp/usr/bin/JxrEncApp -i input.bmp -o output.jxr -q 0.9
