Open XML Paper Specification (also referred to as OpenXPS) is an open specification for a page description language and a fixed-document format. Microsoft developed it as the XML Paper Specification (XPS). It is an XML-based (more precisely XAML-based) specification, based on a new print path (print processing data representation and data flow) and a color-managed vector-based document format that supports device independence and resolution independence.
This is a format for storing graphical vector images used in the Adobe Illustrator program and other software for processing vector graphics. EPS can have a binary or ASCII structure. It can contain raster images, 2D vector graphics and text. It’s also applied as a convenient format for transmitting images among several programs or operation systems.
