RTL-Language Test in libGDX

This is a simple project can be render RTL language correctly using BitmapFont and FreeType:

Support both RTL & LTR.

---

1. Using BitmapFont

1. Open Hiero.jar.
2. Put any freetype font .ttf , .otf which support RTL languages into Hiero.jar.
3. Add RTL letters in Hiero.
4. Save it as .fnt file and import it into assets folder in your project.

• Example

1. RTL letters:

2. Code

ArFont arFont = new ArFont();
arFont.getText("string");     // text putting as a parameter to return correct RTL, LTR or both string.
arFont.typing('char');        // type arabic letter by letter.

---

2. Using FreeType

FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("fonts/jf_flat.ttf"));
FreeTypeFontGenerator.FreeTypeFontParameter parameter = new FreeTypeFontGenerator.FreeTypeFontParameter();
        
parameter.characters += ArUtils.getAllChars().toString(""); // Arabic characters addition to exist characters.
parameter.size = 48;
parameter.color = Color.BROWN;
parameter.borderColor = Color.GOLD;
parameter.borderWidth = 1.5f;
parameter.minFilter = Texture.TextureFilter.Linear;
parameter.magFilter = Texture.TextureFilter.Linear;

BitmapFont freeTypeFont = generator.generateFont(parameter);

That's it
