PS Files the PostScript format for Graphics and Text (original) (raw)
PS is a data directory which contains examples of PS or PostScript files. PostScript is primarily designed to present publication-quality text. A PostScript file consists of a set of images of pages. These pages can include graphics, or in fact consist entirely of graphics.
As a graphic language, PostScript is basically vector-based rather than bit-mapped. Thus, it's easy to draw a square or a star, or even a filled polygonal region. But it's rather unnatural, in PostScript, to define a rectangular region in which every pixel has an assigned color. If a highly detailed bit-map image is needed, it is often computed in another format, such as GIF, and then "imported" into the PostScript file.
PS File Characteristics:
- ASCII (although they can sometimes be set up to include binary data!);
- Color or black and white;
- 2D;
- No compression;
- Based on vectors (descriptions of points, lines and regions) rather than bit maps;
- multiple images (pages).
