  "textContent": "In one embodiment, a method includes accessing a magnetic map of an area that includes magnetic-field values for locations in the area. The method also includes accessing an image file that includes pixels that correspond to the locations and include components. The image file also includes a first matrix with elements that each include color values. The components of the pixels include links to elements in the first matrix. The method also includes embedding portions of the magnetic map into the image file by generating a second matrix for the image file including elements that represent the magnetic-field values and, for the locations in the area, writing to the components of the pixels corresponding to the locations links to elements of the second matrix. The method also includes communicating the image file, with the portions of the magnetic map embedded in it, to computing devices for navigation or localization.",
