Use ZXing camera decoding confusion
<p>I check the Internet and see using ZXing to solve two-dimension code. But the code I do not understand.</p>

<pre><code>PlanarYUVLuminanceSource source = new PlanarYUVLuminanceSource( data, width, height, dstLeft, dstTop, dstWidth,dstHeight, false);
</code></pre>

<p>What the meaning of the parameter? </p>
