image_palette_generator
Generate a color palette from an image or find dominant color.
Samples
Currently, you can extract:
- Dominant Color: Most prominent color in the image.
- Color Palette: A set of catchy colors taken from the image, sorted according to vibrancy.
- Color Tones: A set of normalized colors taken from various areas of the image, sorted according to luminance.
Example
Currently only C++ API is available.
Instantiate the class.
auto palette_generator = ImagePaletteGenerator{};
Open an image source.
// A file path.
palette_generator.Open("/home/user/image.jpeg");
// A FILE*
FILE* file = fopen(argv[1], "rb");
palette_generator.Open(file);
// An encoded image buffer.
palette_generator.Open(static_cast<uint8_t>(buffer), 1024);
Extract dominant color, palette or tones.
auto color = palette_generator.GetDominantColor();
std::vector<Color> palette = palette_generator.GetPalette();
for (const auto &color: palette) {
std::cout << color.ToString() << "\n";
}
std::vector<Color> tones = palette_generator.GetTones();
for (const auto &color: tones) {
std::cout << color.ToString() << "\n";
}
