Property	Description
speed	Angle speed
isLoading	If 'true' shows symbols on rectangle
setEnd	Shows end animation (optionally you may pass onEnd(OnEnd))
rectWidth	Width each of rectangle
period	Determine period of cosinusoidal function
colorAdapter	Define color changes by two parameters (position count, height percent) for each rectagle
offset	Moving bottom offset
directionRight	Determine movement side

There are 6 default ColorAdapter implementation in box :

• DefaultColorAdapterGB (Green -> Blue)
• ColorAdapterBG (Blue -> Green)
• ColorAdapterBR (Blue -> Red)
• ColorAdapterGR (Green -> Blue)
• ColorAdapterRB (Red -> Blue)
• ColorAdapterRG (Red -> Green)
• ColorAdapterBG (Blue -> Green)

There are 2 default TextAdapter implementation in box :

• DefaultBinaryTextAdapter (shows random [0, 1] symbols in each rectagle)
• WordTextAdapter (shows specified cycle String)

ColorAdapter overriding example :

public class ColorAdapterBR implements Cosin.ColorAdapter {

    @Override
    public int getBackgroundColor() {
        return Color.TRANSPARENT;
    }

    @Override
    public int calcColor(int numOfRect, double percentOfHeight) {
        return Color.argb(150, (int)(255 * (1d - percentOfHeight)), 0, (int)(255 * percentOfHeight));
    }
}

TextAdapter overriding example :

public class WordTextAdapter implements Cosin.TextAdapter {

    private String word;

    public WordTextAdapter(String word) {
        this.word = word;
    }

    @Override
    public char getString(int numOfRect) {
        if (word.isEmpty()) return ' ';
        return word.charAt(numOfRect % word.length());
    }
}
