PGM Raw in het kort
PGM Raw
The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.
NCX in het kort
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.
