If the bitmap's internal config is in one of the public formats, return that config, otherwise return null.

Usage

From source file:Main.java

    }//from ww w  . j av  a2  s.  com
    // resource bitmaps are imutable,
    // so we need to convert it to mutable one
    bitmap = bitmap.copy(bitmapConfig, true);

    Canvas canvas = new Canvas(bitmap);
    // new antialised Paint
    Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
    // text color - #808080

    // text size in pixels
    paint.setTextSize((int) (14 * scale * 5));
