    • (experimental) Reads raster data from the best fitting image. This function uses the image with the lowest resolution that is still a higher resolution than the requested resolution. When specified, the bbox option is translated to the window option and the resX and resY to width and height respectively. Then, the [readRasters]GeoTIFFImage#readRasters method of the selected image is called and the result returned.

      Parameters

      Returns Promise<ReadRasterResult>

      the decoded array(s), with height and width, as a promise
