HEIF in het kort
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.
VML in het kort
VML
VML emerged as a 1998 W3C submission backed by Microsoft and partners such as Autodesk, Hewlett-Packard, Macromedia, and Visio, reflecting the moment when web graphics standards were still unsettled.
