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.

HEIF in sintesi

HEIF

HEIF was developed by MPEG and built on the ISO Base Media File Format lineage, which helps explain why it feels more like a modern media container for images than a simple legacy bitmap file.
