Image Processing – Draw Text on a Curve

Just watching on StackOverflow and found this interesting question: How to write curve text?

Here what I’ve tried so far:

Drawing Text on a Curve

Here my implementation:

01	package pete.android.study;

02

03	import android.content.Context;

04	import android.graphics.Canvas;

05	import android.graphics.Color;

06	import android.graphics.Paint;

07	import android.graphics.Path;

08

09	import android.graphics.RectF;

10	import android.view.View;

11

12	public class GraphicsView extends View {

13	private static final String MY_TEXT = "xjaphx: Draw Text on Curve";

14	private Path mArc;

15

16	private Paint mPaintText;

17

18	public GraphicsView(Context context) {

19	super(context);

20

21	mArc = new Path();

22	RectF oval = new RectF(50,100,200,250);;

23	mArc.addArc(oval, -180, 200);

24	mPaintText = new Paint(Paint.ANTI_ALIAS_FLAG);

25	mPaintText.setStyle(Paint.Style.FILL_AND_STROKE);

26	mPaintText.setColor(Color.WHITE);

27	mPaintText.setTextSize(20f);

28

29

}

30

31

@Override

32	protected void onDraw(Canvas canvas) {

33	canvas.drawTextOnPath(MY_TEXT, mArc, 0, 20, mPaintText);

34	invalidate();

35

}
