// lossy or lossless way with a component (symbol) mode. It divides the image into components.
// Then checks if any component is 'similar' to the others and maps them together. The symbol classes are stored
// in the dictionary. Then the encoder creates text regions which uses the related symbol classes to fill it's space.
