        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 1;
        if (height > reqHeight || width > reqWidth) {
            final int heightRatio = Math.round((float) height
                    / (float) reqHeight);
            final int widthRatio = Math.round((float) width
                    / (float) reqWidth);

            inSampleSize = heightRatio < widthRatio ? heightRatio
                    : widthRatio;//from  w  ww  .  ja  va2  s .c  o  m

        }
