VIFF File Format

Khoros Visualization Image category

VIFF is the image format of the Khoros software system, a research toolkit from the early days of scientific visualization. Still found in legacy academic image-processing datasets.

Typical use: Convert legacy VIFF datasets to PNG for modern viewing and notebooks.

About the VIFF format

VIFF is the image format of the Khoros software system, a visual-programming environment built for scientific image processing in the late 1980s and 1990s. Its files carry raster data plus optional attribute lists, and it survives today mostly in older academic datasets and image-processing course material.

Modern software rarely opens VIFF without help. Converting VIFF to PNG puts legacy research imagery into a format every viewer, notebook and browser understands — useful when reviving old datasets or coursework.

Strengths

  • ✓ Holds multi-band scientific raster data
  • ✓ Attribute lists travel with the image
  • ✓ Simple, fully documented binary layout

Limitations

  • ✗ Tied to discontinued Khoros tooling
  • ✗ No browser or OS support
