How can i merge two bitmap one over another at selected point on the first image in android?

Question

How can i merge two different images as one. Also i need to merge the second image at a particular point on the first image. Is it posible in android??

hi Md Abdul Gafur, I need to merge one image over another. I have done that.. but now i need to do the merging in such a manner that i can add the second image at a position where i need to place it...(eg:Suppose a persons picture as the first image and a bubble as the second image.. i need to place the bubble on the to of his head). — Droid_Dev, Jul 04 '12 at 05:36

This should work:

Create a canvas object based from the bitmap.
Draw another bitmap to that canvas object (methods will allow you specifically set coordinates).
Original Bitmap object will have new data saved to it, since the canvas writes to it.

I guess this function can help you:

private Bitmap mergeBitmap(Bitmap src, Bitmap watermark) {
      if (src == null) {
         return null;
      }
      int w = src.getWidth();
      int h = src.getHeight();

      Bitmap newb = Bitmap.createBitmap(w, h, Config.ARGB_8888);
      Canvas cv = new Canvas(newb);

      // draw src into canvas
      cv.drawBitmap(src, 0, 0, null);

      // draw watermark into           
      cv.drawBitmap(watermark, null, new Rect(9, 25, 154, 245), null);

      // save all clip
      cv.save(Canvas.ALL_SAVE_FLAG);

      // store
      cv.restore();

      return newb;
   }

It draws the water mark onto "src" at specific Rect.
