摘要

数以十亿计的文档以可移植文档格式(PDF)存储。这些文档包含了丰富的信息，但PDF通常被视为一种无法访问的格式，因此，经常得到非常糟糕的报道。在本教程中，我们将深入了解PDF，并分析导致PDF文件无法访问的不良实践。我们讨论了如何访问PDF中的文本和图形，并确定了PDF的那些可用于使信息更易于访问的特性。我们还讨论了一些新的ISO标准，这些标准为生成可访问PDF文件提供了配置文件。

DOCENG 2014: PDF tutorial

Many billions of documents are stored in the Portable Document Format (PDF). These documents contain a wealth of information and yet PDF is often seen as an inaccessible format and, for that reason, often gets a very bad press. In this tutorial, we get under the hood of PDF and analyze the poor practices that cause PDF files to be inaccessible. We discuss how to access the text and graphics within a PDF and we identify those features of PDF that can be used to make the information much more accessible. We also discuss some of the new ISO standards that provide profiles for producing Accessible PDF files.
