tonemapper — A tool for exploring and applying various tonemapping operators.

Tonemapper is a an application to compare and apply various tone mapping operators...

... either via an interactive GUI:

./tonemapper

... or via the command line interface:

# Example: apply the "Reinhard" operator with gamma=2.2 to a list of input images
./tonemapper --no-gui --operator reinhard --gamma 2.2 <images>

Clone the repository recursively all dependencies and use CMake to generate project files for your favourite IDE or build system.

# Unix example using make:
git clone https://github.com/tizian/tonemapper.git --recursive
cd tonemapper
mkdir build
cd build
cmake ..
make

Optionally, the compilation of the GUI can be disabled via a CMake option:

cmake .. -DTONEMAPPER_BUILD_GUI=OFF
