It is a dynamically typed, concatenative programming language and was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1. It is used as a page description language in the electronic publishing and desktop publishing. History[edit]The concepts of the Post. Script language were seeded in 1. John Warnock was working at Evans & Sutherland, a computer graphics company. At that time John Warnock was developing an interpreter for a large three- dimensional graphics database of New York harbor. Warnock conceived the Design System language to process the graphics. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1. 97. 5- 7. 6 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a successor. In 1. 97. 8 Evans & Sutherland asked Warnock to move from the San Francisco Bay Area to their main headquarters in Utah, but he was not interested in moving. He then joined Xerox PARC to work with Martin Newell. They rewrote Design System to create J & M (for "John and Martin") which was used for VLSI design and the investigation of type and graphics printing. This work later evolved and expanded into the Interpress language. Warnock left with Chuck Geschke and founded Adobe Systems in December 1. They, together with Doug Brotz, Ed Taft and Bill Paxton created a simpler language, similar to Interpress, called Post. Script, which went on the market in 1. At about this time they were visited by Steve Jobs, who urged them to adapt Post. Script to be used as the language for driving laser printers. In March 1. 98. 5, the Apple. Laser. Writer was the first printer to ship with Post. Script, sparking the desktop publishing (DTP) revolution in the mid- 1. The combination of technical merits and widespread availability made Post. Script a language of choice for graphical output for printing applications. For a time an interpreter (sometimes referred to as a RIP for Raster Image Processor) for the Post. Script language was a common component of laser printers, into the 1. However, the cost of implementation was high; computers output raw PS code that would be interpreted by the printer into a raster image at the printer's natural resolution. This required high performance microprocessors and ample memory. The Laser. Writer used a 1. MHz Motorola 6. 80. Macintosh computers to which it attached. When the laser printer engines themselves cost over a thousand dollars the added cost of PS was marginal. But as printer mechanisms fell in price, the cost of implementing PS became too great a fraction of overall printer cost; in addition, with desktop computers becoming more powerful, it no longer made sense to offload the rasterisation work onto the resource- constrained printer. By 2. 00. 1, few lower- end printer models came with support for Post. Script, largely due to growing competition from much cheaper non- Post. Script ink jet printers, and new software- based methods to render Post. Script images on the computer, making them suitable for any printer; PDF, a descendant of Post. Script, provides one such method, and has largely replaced Post. Script as de facto standard for electronic document distribution. On high- end printers, Post. Script processors remain common, and their use can dramatically reduce the CPU work involved in printing documents, transferring the work of rendering Post. Script images from the computer to the printer. Post. Script Level 1[edit]The first version of the Post. Script language was released to the market in 1. The term "Level 1" was added when Level 2 was introduced. Post. Script Level 2[edit]Post. Script Level 2 was introduced in 1. RIP separations, image decompression (for example, JPEG images could be rendered by a Post. Script program), support for composite fonts, and the form mechanism for caching reusable content. Post. Script 3[edit]Post. Script 3 (Adobe dropped the "level" terminology in favor of simple versioning) came at the end of 1. Post. Script 3 was significant in terms of replacing the existing proprietary color electronic prepress systems, then widely used for magazine production, through the introduction of smooth shading operations with up to 4. Post. Script Level 2), as well as Device. N, a color space that allowed the addition of additional ink colors (called spot colors) into composite color pages. Use in printing[edit]Before Post. Script[edit]Prior to the introduction of Post. Script, printers were designed to print character output given the text—typically in ASCII—as input. There were a number of technologies for this task, but most shared the property that the glyphs were physically difficult to change, as they were stamped onto typewriter keys, bands of metal, or optical plates. This changed to some degree with the increasing popularity of dot matrix printers. The characters on these systems were drawn as a series of dots, as defined by a font table inside the printer. As they grew in sophistication, dot matrix printers started including several built- in fonts from which the user could select, and some models allowed users to upload their own custom glyphs into the printer. Dot matrix printers also introduced the ability to print raster graphics. The graphics were interpreted by the computer and sent as a series of dots to the printer using a series of escape sequences. These printer control languages varied from printer to printer, requiring program authors to create numerous drivers. Vector graphics printing was left to special- purpose devices, called plotters. Almost all plotters did share a common command language, HPGL, but were of limited use for anything other than printing graphics. In addition, they tended to be expensive and slow, and thus rare. Post. Script printing[edit]Laser printers combine the best features of both printers and plotters. Like plotters, laser printers offer high quality line art, and like dot- matrix printers, they are able to generate pages of text and raster graphics. Unlike either printers or plotters, however, a laser printer makes it possible to position high- quality graphics and text on the same page. Post. Script made it possible to fully exploit these characteristics, by offering a single control language that could be used on any brand of printer. Post. Script went beyond the typical printer control language and was a complete programming language of its own. Many applications can transform a document into a Post. Script program whose execution will result in the original document. This program can be sent to an interpreter in a printer, which results in a printed document, or to one inside another application, which will display the document on- screen. Since the document- program is the same regardless of its destination, it is called device- independent. Post. Script is noteworthy for implementing on- the fly rasterization; everything, even text, is specified in terms of straight lines and cubic Bézier curves (previously found only in CAD applications), which allows arbitrary scaling, rotating and other transformations. When the Post. Script program is interpreted, the interpreter converts these instructions into the dots needed to form the output. For this reason Post. Script interpreters are occasionally called Post. Script Raster Image Processors, or RIPs. Font handling[edit]Almost as complex as Post. Script itself is its handling of fonts. The font system uses the PS graphics primitives to draw glyphs as line art, which can then be rendered at any resolution. A number of typographic issues had to be considered with this approach. One issue is that fonts do not actually scale linearly at small sizes; features of the glyphs will become proportionally too large or small and they start to look wrong. Post. Script avoided this problem with the inclusion of font hinting, in which additional information is provided in horizontal or vertical bands to help identify the features in each letter that are important for the rasterizer to maintain. The result was significantly better- looking fonts even at low resolution; it had formerly been believed that hand- tuned bitmap fonts were required for this task. At the time, the technology for including these hints in fonts was carefully guarded, and the hinted fonts were compressed and encrypted into what Adobe called a Type 1 Font (also known as Post. Script Type 1 Font, PS1, T1 or Adobe Type 1). Type 1 was effectively a simplification of the PS system to store outline information only, as opposed to being a complete language (PDF is similar in this regard). Adobe would then sell licenses to the Type 1 technology to those wanting to add hints to their own fonts. Those who did not license the technology were left with the Type 3 Font (also known as Post. Script Type 3 Font, PS3 or T3). Type 3 fonts allowed for all the sophistication of the Post. Script language, but without the standardized approach to hinting. The Type 2 font format was designed to be used with Compact Font Format (CFF) charstrings, and was implemented to reduce the overall font file size. The CFF/Type. 2 format later became the basis for handling Post. Script outlines in Open.
