LibGDX Tutorial 4: Creating a Sprite

This is the image used:

Create projects using gdx-setup-ui.jar:

Objectives

• Set Texture into Sprite
• Set Sprite Size
• Set Sprite Offset

Program
 Below I display the same sprite 12 times, and in each render there is a slightly different offset. I set the GL2 flag to true in Main.java so the images do not have to be power of 2.
cfg.useGL20 = true; //** Code in Main.java of the desktop project **//

MyCircleSprite.java
package com.tutorials.circlesprite;

import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.Texture.TextureFilter;
import com.badlogic.gdx.graphics.g2d.Sprite;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class MyCircleSprite implements ApplicationListener {
    private OrthographicCamera camera;
    private SpriteBatch batch;
    private Texture texture;
    private Sprite sprite;
    private int rotation;
   
    @Override
    public void create() {       
        float w = Gdx.graphics.getWidth();
        float h = Gdx.graphics.getHeight();
        camera = new OrthographicCamera(1, h/w);
        batch = new SpriteBatch();
        texture = new Texture("circleSprite.png");
        texture.setFilter(TextureFilter.Linear, TextureFilter.Linear); //** for scaling **//
        sprite = new Sprite(texture);
        sprite.setSize(0.1f, 0.3f); //** sprite size in screen coordinates **//
        sprite.setOrigin(0.05f,0); //** relative origin for rotation **//
    }

    @Override
    public void dispose() {
        batch.dispose();
        texture.dispose();
    }

    @Override
    public void render() {
        rotation=(rotation + 1) % 360; //** angle keeps on increasing **//
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
        batch.setProjectionMatrix(camera.combined);
        batch.begin();
        for (int i=0; i<12; i++) {
            sprite.setRotation(i*30+rotation);
            sprite.draw(batch);
        }
        batch.end();
        Gdx.app.log("my Circle App", "Frame Rate: " +1/Gdx.graphics.getDeltaTime());
    }

    @Override
    public void resize(int width, int height) {
    }

    @Override
    public void pause() {
    }

    @Override
    public void resume() {
    }
}

This is the output at a specific time:
