A tool for performing black and white Bayer dithering, written in C++17.
# Use the 8x8 Bayer kernel (currently available sizes are 2x2, 4x4, and 8x8).
# Increase pre-dithering brightness by 30 (pixel intensity values range from 0-255).
# Increase pre-dithering contrast by 15%.
# For the PNG output format, a bit depth of 1 is automatically selected.

There are a few dependencies required to build this tool:
- libvips (https://github.com/libvips/libvips)
The recommended way of building this project is as follows:
- Grab the source code
git clone https://github.com/nilssonk/ordered-dithering-cpp
cd ordered-dithering-cpp
- Run CMake to configure and build the project using presets and ninja-build
# Clang Debug build with clang-tidy static analysis enabled
cmake --preset=clang-debug .
cmake --build --preset=clang-debug
# GCC Release build with LTO enabled
cmake --preset=gcc-release-lto .
cmake --build --preset=gcc-release-lto
If all goes well, the executable can then be found at main/ordered_dithering_main inside the build directory (default ${sourceDir}/build).
