Converting HEIC to FITS

HEIC (High Efficiency Image File Format) is a new image container format from the developers of MPEG. HEIC format is used by Apple as default image format on iOS. HEIC is used to save phone memory and considered as a better and easy way to distribute images.

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.
