# pyrawdecode Script for decoding raw bayer images. ## Install You need to install following Python modules: - pip3 install pillow - pip3 install numpy ## Supported raw formats - RAW8: 8bits per pixel - RAW10: 10bits per pixel - RAW12: 12bits per pixel - RAW16: 1-16bits per pixel. LE and BE. Byte order | BYTE_1 | BYTE_2 | BYTE_3 | BYTE_4 | BYTE_5 | BYTE_6 | ... ----------------------------------------------------------------------------------------------------------- - RAW8: | P1 | P2 | P3 | P4 | P5 | P6 | ... - RAW10: | P1_MSB | P2_MSB | P3_MSB | P4_MSB | P1_2_3_4_LSB | P5_MSB | ... - RAW12: | P1_MSB | P2_MSB | P1_2_LSB | P3_MSB | P4_MSB | P3_4_LSB | ... - RAW16 (LE):| P1_MSB | P1_LSB | P2_MSB | P2_LSB | P3_MSB | P3_LSB | ... - RAW16 (BE):| P1_LSB | P1_MSB | P2_LSB | P2_MSB | P3_LSB | P3_MSB | ... ## Usage ``` usage: rawdecode.py [-h] [--file FILE] [--dir DIR] [--outdir OUTDIR] [--width WIDTH] [--height HEIGHT] [--headerbytes HEADERBYTES] [--leftbytes LEFTBYTES] [--rightbytes RIGHTBYTES] [--bayerorder BAYERORDER] [--encoding ENCODING] [--bpp BPP] [--endian ENDIAN] [--png] [--jpg] [--components] [--plain16] [--rgb] [--display] [--wb WB WB WB] [input] Raw image decoder positional arguments: input input file optional arguments: -h, --help show this help message and exit --file FILE input file --dir DIR input directory --outdir OUTDIR Output folder --width WIDTH width --height HEIGHT height --headerbytes HEADERBYTES Header Bytes before image data --leftbytes LEFTBYTES Extra Bytes left of image data on every line --rightbytes RIGHTBYTES Extra Bytes right of image data on every line --bayerorder BAYERORDER Bayer order: [GRBG,RGGB,BGGR,GBRG] --encoding ENCODING Raw format: raw8, raw10, raw12, raw16. Default: read from extension. --bpp BPP Bits per pixel in raw image: 1-16, if different than encoding suggests. Bpp will be used to shift data to 16bpp. Default: read from extension --endian ENDIAN Use defined endianness when writing or reading 16 bit values (read/write .raw16). [le, be]. Default: le --png Save decoded raw files as png (16bit) --jpg Save decoded raw files as jpg (8bit) --components Save Gr, R, B, Gb components as separate png --plain16 Save Plain16 (.raw16) as 16bpp binary --rgb Save RGB output (half resolution at the moment) as png (8bit) --display Show processed image --wb WB WB WB White balance RGB gains: [R, G, B] - applied only for RGB export. Default: 1.0 1.0 1.0 ``` ## Command line examples ``` Decode RAW10 file and save it as png, plain16, rgb (half resolution) and separate components as png. % python3 rawdecode.py --width 3840 --height 2160 --file image.raw10 --rgb --plain16 --png --components ``` ## Backlog ``` - Format and parameter checking - Verify RAW8 - Verify RAW12 - Add Demosaic - Add Gamma - Add Black level - Add 3x3 color matrix ```
