您可以将任何适合您的应用程序的内容写到PDF中，包括图像，文本，路径图，还可以添加链接和加密.有关更多信息，请参见"PDF文档的创建，查看和转换"(第177页) )."
"You can write any content to a PDF that’s appropriate for your application—images, text, path drawing—and you can add links and encryption. For more information see "PDF Document Creation, Viewing, and Transforming" (page 177)."
