Convert FF to J2C

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.

The J2C file extension stands for JPEG 2000 Code Stream, a format defined in Part 1 of the JPEG 2000 standard. Developed by the Joint Photographic Experts Group (JPEG) from 1997 to 2000, J2C files utilize wavelet-based compression, supporting both lossy and lossless compression. This format is primarily used for high-quality image storage and transmission, offering superior compression efficiency and flexibility compared to the original JPEG standard. J2C files are often embedded within other file formats like JP2 for enhanced metadata support.
