افت کیفیت بعد کراپ کردن تصویر موقع نمایش چرا؟!

سلام.

افت کیفیت بعد کراپ کردن تصویر موقع نمایش چرا؟!

 private void performCrop(String picUri) {
    try {
      //Start Crop Activity
      Intent cropIntent = new Intent("com.android.camera.action.CROP");
      // indicate image type and Uri
      File f = new File(picUri);
      Uri contentUri = Uri.fromFile(f);
      cropIntent.setDataAndType(contentUri, "image/*");
      // set crop properties
      cropIntent.putExtra("crop", "true");
      // indicate aspect of desired crop
      cropIntent.putExtra("aspectX", 1200);
      cropIntent.putExtra("aspectY", 800);
      // indicate output X and Y
      cropIntent.putExtra("outputX", 450);
      cropIntent.putExtra("outputY", 300);
      // retrieve data on return
      cropIntent.putExtra("return-data", true);
      //cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, picUri);
      startActivityForResult(cropIntent, 3);
    }
    // respond to users whose devices do not support the crop action
    catch (ActivityNotFoundException anfe) {
      // display an error message
      String errorMessage = "your device doesn't support the crop action!";
      Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
      toast.show();
    }
  }

 @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode==1 && resultCode==RESULT_OK && data!=null){
      /*Uri img =data.getData();
      Log.i("Uri","Uri is : " + img);
      String[] af={MediaStore.Images.Media.DATA};
      Cursor cu = getContentResolver().query(img, af, null, null, null);
      cu.moveToFirst();
      int ci=cu.getColumnIndex(af[0]);
      path = cu.getString(ci);
      cu.close();
      imgView.setImageBitmap(BitmapFactory.decodeFile(path));
      Toast.makeText(App.currentActivity,path,Toast.LENGTH_LONG).show();*/
      Bundle extras = data.getExtras();
      Bitmap image = extras.getParcelable("data");
      imgView.setImageBitmap(image);

    }
