Yet Another Previewer (Paperback)

High Quality Content by WIKIPEDIA articles! Yet Another Previewer (or YAP) is the name of two different document previewing applications, one for DVI and one for PostScript. The YAP for PostScript previewing is used to dynamically edit and re-render PostScript as if one was editing a file, unlike the actual PostScript interpreter itself (such as ghostscript), which deals with PostScript input interactively from a user. YAP first was bundled with the NeXT demos package of NeXTSTEP, which was also bundled with OPENSTEP. It was not carried into its incarnation as Mac OS X, presumably because of PostScript's lessened importance with the OS X subsystems relying on Display PDF instead. The YAP for DVI viewing is a program bundled with the widely used MiKTeX TeX distribution for the Microsoft Windows platform. YAP allows zooming in and out by several integer factors, besides having a "magnifying glass" feature for local zooming.
