// WIP: In order to obtain better compression results the encoder would allow to encode the input in a
// 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.
// The similarity is defined by the 'Threshold' variable (default: 0.95). The less the value is, the more components
// matches to single class, thus the compression is better, but the result might become lossy.
