Allows for reducing the R/G/B color channel bit-depth of images (RGB-888/RGBA-8888) to between 1-8 bits. The channel bit-depths can be locked together or modified separately.
For example it can reduce an RGB-888 image to bit-depths used by old game consoles such as the Game Boy Color(BGR-555), Game Gear(BGR-444), or Sega Master System(BGR-222).
The functionality is similar to the built-in Colors -> Dither plugin except that it ensures alignment of color reductions to be within scaled bit-depth boundaries instead of arbitrary ranges.
The plugin menu location is: Colors -> Reduce Color Bit-Depth...
At least compatible with some versions of GIMP 2.10 on Linux and Windows.
