DECE-Graphic

DECE-Graphic Strengths

  • Allowed the UltraViolet DRM ecosystem to easily distinguish structural UI/cover graphic assets from actual encrypted video tracks in a Common File Format container
Limitations
  • Completely obsolete since the 2019 shutdown of UltraViolet
  • Unnecessary abstraction, as the underlying files were just standard JPEGs or PNGs
  • Causes modern strict MIME-type validators to fail if they rely on the Content-Type header
FreeHand

FreeHand Strengths

  • Historically one of the most powerful and intuitive vector editors on the market, praised for multi-page support long before Adobe Illustrator implemented it
  • Files are generally compact and self-contained
Limitations
  • Completely abandoned proprietary format; Adobe actively blocked native import in modern versions of Illustrator
  • No support in modern web browsers; must be converted to SVG
  • Versioning fragmentation means parsers must account for wildly different binary structures depending on the specific .fhX extension used
