Convert FPX to FF

The FPX file extension stands for FlashPix Format, a bitmap image format developed in 1996 by Kodak, Microsoft, Hewlett-Packard, and Live Picture. It was designed to handle large image files efficiently by storing images at multiple resolutions within a single file, allowing quick access to the appropriate resolution based on display requirements. FlashPix uses Microsoft's structured storage format, which organizes hierarchical data in a single file. This format was particularly useful for digital photography and imaging applications, optimizing storage and bandwidth usage.

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.
