Xamarin“ DetectScreenSize”配方：

> PCA1$map[[1]]
class       : RasterLayer 
dimensions  : 1352, 3570, 4826640  (nrow, ncol, ncell)
resolution  : 0.1, 0.1  (x, y)
extent      : -177, 180, -56.07567, 79.12433  (xmin, xmax, ymin, ymax)
coord. ref. : +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0 
data source : /private/var/folders/3c/tsrm9qxs7t323jrz5k8h4d600000gn/T/RtmpKORCX5/raster/r_tmp_2018-11-17_002746_40497_32387.grd
