X3F in sintesi
X3F
Sigma raw support is closely tied to the company's Foveon sensor story, giving X3F a reputation and workflow profile that differ from more mainstream Bayer-centric raw ecosystems.
NCX in sintesi
NCX
NCX was defined in the 2005 DAISY and ANSI-NISO talking-book standard, then carried forward into EPUB 2 and later treated as a legacy compatibility feature once EPUB 3 introduced XHTML navigation documents.
