Features:
- Thumbnail extraction
- Thumbnail jpeg preview
- Exif
- Worker thread
- Added ACEScg, ACEScc, ACEScct
- For ACES color space - EXR file output like rawtoaces
- Fast I/O Buffer from/to JS/WASM
- Jpeg preview for tiff output - turbojpeg C++
- Thread safe
- Easy JS<-->C++ memory management: internally managed inside C++
Write options:
-c float-num Set adjust maximum threshold (default 0.75)
-v Verbose: print progress messages (repeated -v will add verbosity)
-w Use camera white balance, if possible
-a Average the whole image for white balance
-A <x y w h> Average a grey box for white balance
-r <r g b g> Set custom white balance
-M +/-M - Use/don't use an embedded color matrix
-C <r b> Correct chromatic aberration
-k <num> Set the darkness level
-S <num> Set the saturation level
-R <num> Set raw processing options to num
-n <num> Set threshold for wavelet denoising
-H [0-9] Highlight mode (0=clip, 1=unclip, 2=blend, 3+=rebuild)
-t [0-7] Flip image (0=none, 3=180, 5=90CCW, 6=90CW)
-o [0-11] Output colorspace (raw,sRGB,Adobe,Wide,ProPhoto,XYZ,ACES2065-1,
ACEScg,DCI-P3,Rec2020,ACEScc,ACEScct)
-j Don't stretch or rotate raw pixels
-W Don't automatically brighten the image
-b <num> Adjust brightness (default = 1.0)

0 - linear, 1 - VNG, 2 - PPG, 3 - AHD, 4 - DCB
11 - DHT, 12 - AAHD
-h Half-size color image (twice as fast as "-q 0")
-f Interpolate RGGB as four colors
-m <num> Apply a 3x3 median filter to R-G and B-G
-s [0..N-1] Select one raw image from input file
-4 Linear 16-bit, same as "-6 -W -g 1 1
-6 Write 16-bit output
-g pow ts Set gamma curve to gamma pow and toe slope ts (default = 2.222 4.5)
-G Use green_matching() filter
-B <x y w h> use cropbox
-T Output thumbnail jpeg
-x Detailed timing report
-F N 0 - disable FBDD noise reduction (default), 1 - light FBDD, 2 - full
-D N Number of extra DCD iterations (default - 0)
-d DCB color enhance
-e <e p> exposure correction
