STX to RIFF Conversion: FAQ

What are STX files?

STX files represent RAW images created with SBIG CCD cameras. They are part of a group of formats known as Santa Barbara Instruments Astronomical Images, also including ST5, ST6, ST7 and ST8. Apart from astronomy, SBIG cameras can also be used in medical imaging, color photometry and a few other scientific and industrial sectors. All formats in the group are considered specialized and rare, so opening STX files might be possible only after conversion to more widely available extensions.

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.
