Convert FITS to FF

The FITS (Flexible Image Transport System) file extension is widely utilized in the field of astronomy for storing, transmitting, and manipulating scientific data and images. Originating in the late 1970s, FITS was developed by NASA and the International Astronomical Union (IAU) to standardize the format for astronomical data. Its primary use is to archive astronomical images, spectral data, and other multidimensional data arrays, enabling efficient data interchange among scientists and astronomers. FITS files are known for their ability to store metadata and large datasets, making them essential for detailed scientific analysis and long-term preservation in research environments.

The Farbfeld (FF) file extension stands for "Farbfeld Lossless Image", a format designed for simplicity and efficiency in parsing and piping image data. Introduced by the Suckless community, Farbfeld stores images in a straightforward, uncompressed format, making it ideal for use with external compression algorithms. This format uses 32-bit RGBA values for each pixel, ensuring lossless quality. Its history traces back to the need for a minimalistic, easily manageable image format that avoids the complexity of integrated compression found in formats like PNG.
