Software Introduction

Adobe Acrobat

The PDF format launched by Adobe is a brand new electronic document format. With Acrobat, you can publish almost all documents in Portable Document Format (PDF). PDF format documents can truthfully retain their original appearance and content, as well as fonts and images. These types of documents can be sent via email or stored on WWW, intranet, file system, or CD-ROM for other users to view on platforms such as Microsoft Windows, macOS, and LINUX. Because the format uses PostScript Page description language developed by Adobe, the quality of text and graphics in the page has been improved. Whether users are using PDF documents for online reading, printing, or publishing, Adobe Acrobat can provide users with the best results.

The latest Adobe Acrobat XI introduces the function of converting PDF to Word and PowerPoint.

PostScript Language

When it comes to PDF, it is necessary to introduce the PostScript language:

PostScript is a Page description language built into many desktop printers and all high-end printing systems. Due to the language being built into many printers, most applications on Macintosh, Windows, and UNIX systems can create PostScript files for printing.

After several years of effort, Adobe has gradually promoted the PostScript language, and through continuous improvements to the PostScript language, it has now become a professional format in the printing and publishing industry. The first version of the PostScript file format, PostScript Level 1, can represent both grayscale Vector graphics and grayscale bitmap images. The second version of PostScript Level 2 can not only represent grayscale vectors and bitmap graphics, but also colors, and supports RGB, CMYK, and CIE based color models for vector and bitmap graphics. (Some PostScript Level 1 files can also represent colors by extending the PostScript language, but this extension has been further popularized in PostScript Level 2.)

PostScript 3 provides additional features for Level 2, including the ability to print gradient mesh objects when printing to a PostScript 3 printer. Due to the need for devices that print to PostScript Levels 1 and 2 to convert gradient mesh objects into bitmap images, it is best to print line drafts containing gradient mesh objects to a PostScript 3 printer. The most commonly used PostScript Level 2 supports many compression techniques for bitmap images, including LZW, CCITT, and JPEG methods.

According to PostScript Level 2 language, PDF can represent both vector and bitmap graphics. PDF pages are equivalent to PostScript pages, but PDF files also include electronic document search and navigation functions. PDF files can also contain hypertext links and electronic catalog tables
