I am able to display a GeoTIFF on my map with this code:
var raster = new Raster(Path.Combine(Android.OS.Environment.ExternalStorageDirectory.AbsolutePath, "eisalley.tiff"));
var rasterLayer = new RasterLayer(raster);
But the image only shows up at a certain zoom level down to a certain zoom level.
I tried to set MinScale and MaxScale for the rasterLayer, but it doesn't change anything.
How can i increase and/or decrease the Scale at which the raster data is rendered?
