The way I have been doing it so far is copying the same font, saving under another name and loading it with different parameters. I am trying to develop an app in LibGDX and by saving the font as different files takes more memory than necessary. Isn't there a way of loading 1 font multiple times, each time with different parameters?
Take a look of this example, I am creating a list of BitmapFont object having different size by simply changing attributes of FreeTypeFontGenerator.FreeTypeFontParameter.
public class MainGame extends Game {
SpriteBatch spriteBatch;
BitmapFont font[];
OrthographicCamera camera;
@Override
public void create() {
camera=new OrthographicCamera();
camera.setToOrtho(false,400,640);
spriteBatch = new SpriteBatch();
int size[]=new int[]{5,8,10,13,15,20,30,40,50,60};
font=new BitmapFont[size.length];
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("BUBBLEGUM.TTF"));
FreeTypeFontGenerator.FreeTypeFontParameter parameter = new FreeTypeFontGenerator.FreeTypeFontParameter();
parameter.color = Color.WHITE;
parameter.magFilter = Texture.TextureFilter.Linear; // used for resizing quality
parameter.minFilter = Texture.TextureFilter.Linear;
for(int i=0;i<size.length;i++){
parameter.size=size[i];
font[i]=generator.generateFont(parameter);
font[i].getRegion().getTexture().setFilter(Texture.TextureFilter.Linear, Texture.TextureFilter.Linear);
font[i].setColor(1.0f, 0.0f, 0.0f, 1.0f);
}
generator.dispose(); // Don't forget to dispose
}
@Override
public void render() {
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
Gdx.gl.glClearColor(1,1,0,1);
spriteBatch.setProjectionMatrix(camera.combined);
spriteBatch.begin();
for (int i=0;i<font.length;i++)
font[i].draw(spriteBatch,"LIBGDX FONT",10,100+i*55);
spriteBatch.end();
}
@Override
public void resize(int width, int height) {
camera.setToOrtho(false,width,height);
}
@Override
public void dispose() {
spriteBatch.dispose();
for(BitmapFont bmfont:font)
bmfont.dispose();
}
}
EDIT
