        int j = getHeight();
        Bitmap.Config localConfig = Bitmap.Config.ARGB_8888;
        Bitmap localBitmap = Bitmap.createBitmap(i, j, localConfig);
        Canvas localCanvas = new Canvas(localBitmap);
        Paint localPaint = new Paint(1);
        localPaint.setColor(-16777216);
        float f1 = getWidth();
        float f2 = getHeight();
        RectF localRectF = new RectF(0.0F, 0.0F, f1, f2);
        localCanvas.drawOval(localRectF, localPaint);
        return localBitmap;
    }
}
