# Grayscaler

Simple educational-purpose image grayscaler

Currently, only jpeg images are supported using `libjpeg`.

## Usage

1. Configure

   You can configure

   - input image name (`INPUT_IMAGE_FILENAME`)

   - output images name (`OUTPUT_IMAGE_FILENAME`)

   configuration variables in [`config.h`](/config.h) file.

2. Build

   ```sh

   cmake -S . -B build -DCMAKE_BUILD_TYPE=Release

   cmake --build build

   ```

   _Change `Release` to `Debug` in order to include debugg symbol files with output executable._

3. Run

   ```sh

   ./build/grayscale

   ```

## Development

You'll need CMake and a C compiler. I used CMake version `3.20.5` and clang version `12.0.1`.

If you want to use another compiler, set its path in `CMakeLists.txt` file (`CMAKE_C_COMPILER` configuration variable).
