  • Designed a custom layout with a image view
  • Inflated it to a view object
  • Set the my image to that image view in layout
  • Drawn the view to a bitmap and saved it

Code for inflating and drawing

    public Bitmap drawToBitmap(Context context, final int layoutResId,
                           final int width, final int height, String imageDescription) {
    final Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
    final Canvas canvas = new Canvas(bmp);
    final LayoutInflater inflater =
            (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    final View layout = inflater.inflate(layoutResId, null);
    ImageView img = layout.findViewById(R.id.imgAnalysedBitmap);
    img.setImageBitmap(croppedBitmap);
    layout.setDrawingCacheEnabled(true);
    layout.measure(
            View.MeasureSpec.makeMeasureSpec(canvas.getWidth(), View.MeasureSpec.EXACTLY),
            View.MeasureSpec.makeMeasureSpec(canvas.getHeight(), View.MeasureSpec.EXACTLY));
    layout.layout(0, 0, layout.getMeasuredWidth(), layout.getMeasuredHeight());
    canvas.drawBitmap(layout.getDrawingCache(), 0, 0, new Paint());
    return bmp;
}

Usage:

final DisplayMetrics metrics = getResources().getDisplayMetrics();
        Bitmap bmap = drawToBitmap(this, R.layout.layout_watermark, metrics.widthPixels, metrics.heightPixels, imageDescription);
