<title>About 1D barcodes</title>

</head>
<body>
<p>Traditional barcodes, such as those printed on product packaging, are also known as <em>one
dimensional barcodes</em>. There are several types commonly used, including UPC and EAN. Most look
similar to this:</p>
<p style="text-align:center"><img src="../images/big-1d.png"></p>
<p style="text-align:center"><img src="../images/big-1d.png" alt="1D"></p>
<p>These 1D barcodes contain a unique code which typically describes a product, like a CD or a book.
You can look this code up on the internet to find prices, reviews, and more.</p>
<p>If you scan a book, you can also search the contents of the book for a word or phrase, and find
all the pages where it appears:</p>
<center><p><img src="../images/search-book-contents.jpg"></p></center>
<p style="text-align:center"><img src="../images/search-book-contents.jpg" alt="Search book contents"></p>

<p>In addition to <a href="about2d.html">scanning 2D barcodes</a>, <b>Barcode Scanner</b> can also
generate a QR Code and display it on your screen. Then you can show it to a friend, and let them
scan the barcode with their phone:</p>
<center><p><img src="../images/scan-from-phone.png" alt="Scan from phone"></p></center>
<p style="text-align:center"><img src="../images/scan-from-phone.png" alt="Scan from phone"></p>
<p>To use this feature, press the Menu button from the main scanning screen, and tap Share. Then
choose whether you want to share a contact, a bookmark, an application, or the contents of the
clipboard. A QR Code will be generated automatically. When you're done, press Back or Home.</p>

* <p>A utility which auto-translates the English-language text in a directory of HTML documents using

*
* <p>Pass the Android client assets/ directory as first argument, and the language to translate to second.
* Optionally, you can specify the files to translate individually.
* Usage: {@code HtmlAssetTranslator android/assets/ es [file1.html file2.html ...]}</p>
*
* <p>This will translate all .html files in subdirectory html-en to directory html-es, for example.
* Note that only text nodes in the HTML document are translated. Any text that is a child of a node
* with {@code class="notranslate"} will not be translated. It will also add a note at the end of
* the translated page that indicates it was automatically translated.</p>
