ABC to FITS Conversion: FAQ

What are ABC files?

ABC (Advanced Bitonal Compression) is a proprietary image format designed by Lead Technologies for storing scanned documents of all types and sizes. The format is included in a larger imaging pack called LeadTools and its main advantage is the use of a 1-bit compression algorithm, allowing great image quality at a smaller file size when compared to other similar formats available. This translates into easier access, storage and transmission, which adds to the option of using lossless or lossy compression.

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.
