The EPS file is a graphic file encoded in the PostScript page description language. EPS stands for Encapsulated PostScript. This format was developed in 1987 by John Warnock and Chuck Geschke, the founders of Adobe, in collaboration with Aldus. The purpose of this technology was todisplay images and graphics on a PC screen and of them print lossless. This is based on the fact that the pixels are calculated mathematically so that no loss, in terms of quality, can take place. The EPS file is considered the basis of our Contemporary PDFsalthough it is now obsolete.
In addition to the image information itself, the EPS file also contains details about the output size. Unlike a standard PostScript file, the EPS format can never exceed one page maximum, but can contain any combination of images, fonts, text, and vectors. This makes it easier to resize this format. Nevertheless, EPS cannot differentiate between vectors and bitmaps and cannot be clearly assigned to an application. This is why Encapsulated PostScripts are rarely used. EPS files usually contain a preview image in tif, wmf, or pict image formats depending on the operating system used.
