Convert JNX to DIB

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.

A Device Independent Bitmap (DIB) is a format for storing bitmap graphics, ensuring compatibility across different devices and platforms. Its primary use is to enable consistent image representation, regardless of the display hardware or software. Originating from early Windows operating systems, DIBs allowed developers to create graphics that would render accurately on various hardware. Today, DIBs are integral in applications needing uniform image display and manipulation, maintaining their relevance in diverse technological contexts.
