The JNX file extension stands for "BirdsEye JNX Raster Map" and is used by Garmin devices like the Alpha 100 and Montana 650 for navigating terrain. It contains a large raster map divided into small tiles for optimized rendering and includes an encrypted unit ID for the specific Garmin device. JNX files are part of the BirdsEye subscription service, allowing fast map rendering and supporting up to 5000 tiles per level. However, they are device-specific and cannot be created from other raster maps.
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.
