PDF Introduction: PDF (Portable Document Format) is an electronic file format developed by Adobe. This file format has nothing to do with the operating system platform. That is to say, PDF files are common in windows, UNIX, and Apple's Mac OS Operating Systems. This feature makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. More and more e-books, product descriptions, company announcements, online materials, and emails are beginning to use PDF files. PDF files have become an industrial standard for digital information.

Adobe designed the PDF file format to support the publishing and publishing of multimedia integrated information across platforms, especially the publishing of network information. To achieve this, PDF has many advantages that cannot be compared with other electronic document formats. PDF file formats can encapsulate text, fonts, formats, colors, and image files independent of devices and resolutions in one file. This format file can also contain electronic information such as hypertext links, sound and dynamic images. It supports special files and provides high integration and security reliability.

Color:
Font fontchinese = new font (bfchinese, 12, Font. normal, new color (0, 0, 0); // black font fontchinese = new font (bfchinese, 12, Font. normal, new color (0,255, 0); // green

Alignment:
Cell. horizontalalignment = element. align_center;
Cell. verticalalignment = element. align_middle;

Underline/strikethrough:
Chunk chunk1 = new chunk ("this text is underlined", fontfactory. getfont (fontfactory. Helvetica, 12, Font. Underline ));
Chunk chunk2 = new chunk ("this font is of Type italic | strikethru", fontfactory. getfont (fontfactory. Helvetica, 12, Font. italic | font. strikethru ));

Encryption:
Public void setencryption (Boolean strength, string userpassword, string ownerpassword, int permissions );
