About formats

JBG is a file extension for images compressed using the JBIG (Joint Bi-level Image experts Group) standard, formally ITU-T Recommendation T.82, completed in 1993 as a successor to the Group 3 and Group 4 fax compression standards. JBIG compression is designed for bi-level (black and white) images but can also handle grayscale and limited-color images by encoding each bit plane separately. The algorithm uses a form of arithmetic coding guided by an adaptive context model: for each pixel, the encoder examines a template of surrounding already-coded pixels to build a probability estimate, then feeds this estimate to a QM-coder (a variant of the Q-coder arithmetic coder) that produces a highly efficient binary output. JBIG achieves 20-40% better compression than Group 4 on typical document images, with the improvement being even larger on halftoned photographs and images with gradual density transitions where Group 4's simple run-length approach is less effective. The standard supports progressive encoding, where a low-resolution version of the image is transmitted first and progressively refined — useful for fax-like applications where the receiver can begin displaying the image before the full-resolution data arrives. One advantage is superior compression of documents containing halftone images: newspapers, magazines, and marketing materials that mix text with photographic halftones compress dramatically better with JBIG than with Group 3/4. The standard's ITU-T backing ensures it is implemented in document imaging hardware and software worldwide. JBG files are supported by ImageMagick and various document imaging tools.

OXPS (Open XPS) is a fixed-layout document format standardized as ECMA-388 in June 2009, representing an evolution of Microsoft's original XPS specification. The format packages fixed-layout pages, fonts, images, and metadata in a ZIP-based Open Packaging Conventions container — the same packaging framework used by DOCX, XLSX, and other Office Open XML formats. Each page is described using an XML markup language that specifies paths, glyphs, images, and canvas elements with precise coordinates, producing documents that render identically regardless of the viewing device or printer. OXPS incorporated several changes from the original XPS: the use of JPEG XR for high dynamic range images, support for the Open Packaging Conventions 2nd edition, and alignment with the Ecma standardization process. Windows 8 and later generate OXPS (rather than XPS) when printing to the Microsoft XPS Document Writer. One advantage is standards-based document fidelity — as an Ecma standard, OXPS provides a vendor-neutral, fully specified format for documents that must look identical everywhere they are rendered, essential for legal filings, regulatory submissions, and archival records. The fixed-layout model is another strength: unlike reflowable formats, OXPS documents preserve exact page composition including precise glyph positioning and vector graphics. Built-in support in Windows and the .NET framework provides native viewing and creation capabilities without third-party software.
