PNM Raw in sintesi
PNM Raw
PNM survived because engineers kept needing a no-drama raster family for scripts, fixtures, codecs, and image-processing experiments where the format should not be the hard part.
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.
