Converter CR2 to JNX

CR2 is a graphic file format developed by the manufacturer of camcorders and cameras Canon. This means that all images made by the equipment of this manufacturer are saved by default in CR2 format (short name from Canon Raw Image File). One of the most attractive properties of images of the specified format is their high quality, even if the file is being edited (color balance, contrast, brightness change). Data for the CR2 format image is obtained directly from the matrix. Among the main drawbacks of the format are the large file size, as well as poor compatibility with other software products.

JNX is a raster map format. It refers to the so-called tile formats, by which you need to understand a large-scale raster image on the map, divided into smaller rectangular parts. This is necessary so that the display of the navigator is accelerated. JNX files are used on Garmin devices to display satellite maps that are available through BirdsEye subscription. In devices for these files, space is allocated on the internal drive in the Garmin \ BirdsEye folder or on the SD card. The coordinates are stored in the form of signed 4-byte integers. The coordinates of the two corners of the map describe two pairs of numbers: one is latitude, the second is longitude. Tiles are standard JPG drawings. Their lion's share in BirdsEye cards is with a resolution of 256 by 256 pixels. There is support for images and larger. Devices are endowed with the ability to display tiles up to 1 megapixel in size. If the sizes go beyond this limit, then the image is automatically reduced with a loss of quality. There is a significant limitation of the JNX format. Such is the rigid binding of cards to a specific device. The JNX format is fully explored. An exception is only part of the loader service data block. However, when you create your own maps, this can be neglected. There is a set of utilities with which you can convert raster maps to JNX format. They serve for reverse conversion. Files in the JNX format have a binding code for the device. Despite this, there are ways to use your own JNX cards in Garmin navigators.
