Overview
Scalable Vector Graphics (SVG) is a family of specifications of an XML-based file format for describing two-dimensional vector graphics, both static and dynamic (i.e. interactive or animated). SVG drew on experience from the designs of both those formats. SVG allows three types of graphic objects: Vector graphics 
, Raster graphics and Text. Graphical objects can be grouped, styled, transformed, and composited into previously rendered objects. The feature set includes nested transformations, clipping paths, alpha masks, filter effects, template objects and extensibility.[1]
PostScript (PS) is a dynamically typed concatenative programming language best known for its use as a page description language in the electronic and desktop publishing areas. PostScript 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 PostScript program is interpreted, the interpreter converts these instructions into the dots needed to form the output. For this reason PostScript interpreters are also sometimes called PostScript Raster Image Processors , or RIPs.[2]
Encapsulated PostScript, or EPS, is a DSC -conforming PostScript document with additional restrictions which is intended to be usable as a graphics file format . In other words, EPS files are more or less self-contained, reasonably predictable PostScript documents that describe an image or drawing and can be placed within another PostScript document. At minimum, an EPS file contains a Bounding-Box DSC comment, describing the rectangle containing the image described by the EPS file. Applications can use this information to lay out the page, even if they are unable to directly render the PostScript inside. EPS, together with DSC's Open Structuring Conventions, form the basis of early versions of the Adobe Illustrator Artwork file format.[3]
