        Bitmap dstBmp = null;
        if (srcBmp.getWidth() >= srcBmp.getHeight()) {

            dstBmp = Bitmap.createBitmap(
                    srcBmp,
                    srcBmp.getWidth() / 2 - srcBmp.getHeight() / 2,
                    0,
                    srcBmp.getHeight(),
                    srcBmp.getHeight()
                    );

        } else {

            dstBmp = Bitmap.createBitmap(
                    srcBmp,
                    0,
                    srcBmp.getHeight() / 2 - srcBmp.getWidth() / 2,
                    srcBmp.getWidth(),
                    srcBmp.getWidth()
                    );
        }
        return dstBmp;
