RIFF to FITS Conversion: FAQ

What are RIFF files?

The Resource Interchange File Format RIFF is a structured multimedia container format developed through a collaboration between Microsoft and IBM in 1991. As an adaptation of the Electronic Arts Interchange File Format (IFF), RIFF implements a tagged chunk architecture where each data segment contains a 4-character identifier, 32-bit size field, and payload data. This design enables hierarchical organization of heterogeneous multimedia streams while maintaining platform-independent data representation through strict little-endian byte ordering.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
