✨ JXRDECAPP(1) ✨ — JxrDecApp 💖

✨ NAME ✨

okay so this is JxrDecApp 🦋, the JPEG XR Decoder Utility. bestie, it's the tool that turns JPEG XR / HD Photo files into images you can actually look at 📸🌸

🌈 DESCRIPTION 🌈

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

The way you run it is:

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

🎀 Options 🎀

  • -i input.jxr/wdp — this is where you feed it your input JPEG XR/HD Photo file name 📥
  • -o output.bmp/pnm/tif/jxr — your output file name 🖼️ bmp is for <=8bpc (BGR), pnm is for >=8bpc (RGB), tif is for >=8bpc (RGB), and jxr is for compressed domain transcode 🔥
  • -c format — picks the uncompressed output format. the options are: 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 🎨
  • -r top left height width — pick a rectangle to decode just that region ✂️
  • -T m — reduced resolution (mipmap) decode 🔍. the options are: 0: full resolution (this is the default), 1: 1/2 res (down-sampled from full res), 2: 1/4 res (native decode), 3: 1/8 res (down-sampled from 1/4 res), 4: 1/16 res (native decode). and for anything bigger than 4, you get 1/(2^m) res (down-sampled from 1/16 res) 🧚
  • -O orientation — flip or rotate your image 🔄. the options are: 0: no transformation (default), 1: flip vertically, 2: flip horizontally, 3: flip vertically & horizontally, 4: rotate 90 degrees CW, 5: rotate 90 degrees CW & flip vertically, 6: rotate 90 degrees CW & flip horizontally, 7: rotate 90 degrees CW & flip vert & horiz 💜
  • -s skip subbands — used for compressed domain transcoding ⚡. the options are: 0: all subbands included (default), 1: skip flexbits, 2: skip highpass, 3: skip highpass & lowpass (DC only)
  • -a alpha decode — how to handle the alpha channel 🫧. the options are: 0: decode without alpha channel, 1: decode only alpha channel, 2: decode image & alpha (default)
  • -p strength — post processing filter strength ✨. the options are: 0: none (default), 1: light, 2: medium, 3: strong, 4: very strong
  • -C — suppress overlapping boundary macro blocks (this is used for compressed domain tile extraction) 🙈
  • -t — display timing information ⏱️
  • -v — display verbose decoder information 🗣️

Example, bestie 🫶:

./debian/tmp/usr/bin/JxrDecApp -i input.jxr -o output.bmp -c 0
