i++;
k--;
}
});

}

case R.id.next:

Bitmap bt=Bitmap.createBitmap(resizedBitmap, 45, 20,240,310, mat, true);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bt.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte byteArray = stream.toByteArray();

Intent i = new Intent(ImageZoomActivity.this,AdjustGoggles.class);
i.putExtra("btmap", bt);
i.putExtra("image", byteArray);
startActivity(i);

return true;

default:

return super.onOptionsItemSelected(item);
}

}


}


using these code i am getting zooming and rotating image how can i get zoomed image bitmap.I want to use zoomed image in next activity.Rotating image is returning resizedBitmap.what i want to do for getting ResultentBitmap for zoomed image.

    beside the hard to understand question (I am getting zooming vs how can I get zoomed) your code is really messy because there is no formatting. Please take the time to improve your question

Use the following to retrieve a zoomed bitmap from original bitmap with same resolution as original bitmap



public static Bitmap getZoomedImage(Bitmap originalImage, float scale) {
Bitmap scaledBitmap = Bitmap.createScaledBitmap(originalImage, (int)(originalImage.getWidth()*scale), (int)(originalImage.getHeight()*scale), false);
return Bitmap.createBitmap(
scaledBitmap,
(scaledBitmap.getWidth()-originalImage.getWidth())/2,
(scaledBitmap.getHeight()-originalImage.getHeight())/2,
originalImage.getWidth(),
originalImage.getHeight());
}
