kitepdf-xps
The reader for XPS and OpenXPS packages, the fixed-page format of ECMA-388. It reads the Microsoft XPS namespace of 2005 and the OpenXPS namespace.
XpsDocument.open(bytes) opens a package, and KiteDoc of the umbrella artifact recognizes it as KiteDocFormat.Xps. An XpsDocument is a KiteDocument, so the viewer, the renderers, search and text selection work on it as on the other formats.
The module reads and renders XPS. It does not write XPS, and it does not check conformance. See XPS and OpenXPS for what it renders.
