XEP Engine

At the heart of each RenderX publishing solution is RenderX XEP Engine. XEP is built around the mature, high-quality formatting kernel developed by RenderX and which has passed several years of deployment in a wide range of environments. XEP is continually improved in the quality of formatting, standards' conformance, support for advanced features and in compliance to strict requirements to the formatted output of print-ready materials.

XEP core product comes with support for output of PDF, PDF/X, PDF/A, PostScript and our own XML output capabilities. Additional output modules are available as add-ons to the core product. These include PDF Forms, AFP, Microsoft XPS, PPML, SVG and HTML formats.

XEP User Guide

XSL Tutorial

XEP is an XSL FO (XSLFO) and SVG processor. It takes input in XML, applies an XSL transformation to build XSL Formatting Objects representation, and then formats the Formatting Objects into all formats supported. XEP supports multiple raster and vector graphic formats. Among them, Scalable Vector Graphics (SVG) is an XML-based vector graphics representation, widely used in business applications and for fine typesetting.



XSL 1.0 Recommendation

SVG 1.1 Specification

Adobe PDF


XEP conforms to Extensible Stylesheet Language (XSL) Version 1.0, a W3C recommendation. It also supports a subset of Scalable Vector Graphics (SVG) 1.1 Specification. XEP outputs formatted documents in Adobe PDF version 1.3 (with optional support for features from newer versions) and PostScript level 2 or 3 formats.

The XEP Engine is written in Java and runs on most Unixes, Microsoft Windows, Linux, Mac OS X and other systems where Java Virtual Machine 1.1.8 or newer is available.
