The only required dependency is oiiotool. However other “debayer engines” are also supported.

• OpenImageIO – oiiotool is used for converting debayered tif images to exr.
• Debayer Engines
  • RawTherapee – Powerful raw development software used to decode raw images. High quality, good selection of debayer algorithms, and more advanced raw processing like chromatic aberration removal.
  • LibRaw – dcraw_emu commandline utility included with LibRaw. Optional alternative for debayer. Simple, fast and effective.
  • Darktable – Uses darktable-cli plus an xmp config to process.
  • vkdt – uses vkdt-cli to debayer. Pretty experimental still. Uses Vulkan for image processing. Stupidly fast. Pretty limited.
