WYSIWYG
WYSIWYG [ wɪziwɪg ] is the acronym for the basic idea of " What You See Is What You Get" ( English for " What you see is [ that ] what you get. " ) - Also known as real image representation known. In a real WYSIWYG document is displayed during editing on the screen exactly as in the output from another device, such as a printer, looks like. The term early 1980s was used in connection with computer typesetting systems ( desktop publishing ) and word processing programs first.
History and more details
The first usable in practice and available device on the market was the set - design - Terminal ( SGT ), a development of the Austrian company Grafotron under their chief designer Hannes Schöllauf. The SCT is able to convert a graphically properly created directly on a screen in a set of commands Linotype CRTronic or Linotronic photo typesetting machine. This one was to be exposed in a position made without set commands sides. The SCT has thus anticipated the later desktop publishing.
In the 1990s the term WYSIWYG was softened by numerous programs in which the output document only looks similar to during processing. Especially with HTML editors, the term is not strictly correct, since the output of an HTML page from the browser and its settings used and possibly the installed system fonts dependent and therefore can vary greatly from viewer to viewer.
" True" WYSIWYG relies on modern computers requires the configuration of a PostScript - compatible driver and the use of PostScript or at least TrueType fonts. In the time of the Home Computer a similar layout fidelity has been achieved by the screen was sent in the original resolution of the printer, as illustrated by the example of Sinclair printer.
WYSIWYG is applied in addition to the editors used by programmers even with content management systems and content management systems to allow editors to edit web pages without knowledge of HTML.
Often there are difficulties in implementation between written text and representation, and therefore a simplified markup language is used as an alternative.
Comments
The term originated during the late 1970s at the Xerox Palo Alto Research Center, as the first WYSIWYG editor, Bravo, was developed on the Alto by Charles Simonyi. The screen of the Alto was able to present a full page text and print them out on the then first laser printers. For the presentation of text on the screen 72 PPI character sets were used. Printing was done, however, with 300 dpi. This led to discrepancies between the display on the screen and the expression - a problem that still exists today. The researchers at the Xerox Palo Alto Research Center used with WYSIWYG is an abbreviation for a then popular catch phrase that was founded by Geraldine, a character from The Flip Wilson Show, into life: " What you see is what you get! ".
The Apple Macintosh system was so designed that the resolution corresponded to the screens and dot matrix printers from Apple. Screens possessed a resolution of 72 PPI. The printer worked with a resolution of 144 dpi. Thus, the output of programs such as MacPaint MacWrite and could be well adapted by doubling the resolution of the printer. WYSIWYG was so easy. With the introduction of laser printers also true WYSIWYG disappeared because the resolution is no longer corresponded to twice the screen resolution.
WYSIWYG means but also a program that is used for lighting design. All well-known productions as well as smaller event technology company, use the WYSIWYG to demonstrate to their customers how their stage will look like once. Many lighting consoles ( consoles that used for lighting control uses ) operate on a secondary level with WYSIWYG, that is, the lighting technician sees on the monitor, which will do its lamps, the next push of a button.
Known WYSIWYG editors for web sites are such as Dreamweaver, GoLive, Microsoft Expression Web, NetObjects Fusion, Quanta Plus, HTMLArea, KompoZer (formerly Nvu ), TinyMCE and CKeditor. See also HTML editor.
