The API itself doesn't offer this functionality, however there is a workaround:

- Get the coordinates for the country border. You can download the coordinates from http://www.gadm.org/[^]
- Put them in a PointF array

C#

PointF[] selectedArea = {
  new PointF(1.12345f, 3.45678f),
  ...
}

- Translate the coordinates in the array to points on your visible tile, this will give you a Point[]. I don't know that part by hard, but this page[^] has a section on Pixel Coordinates showing you the exact lines of code to translate from coordinates to pixels. I paste it here for reference (in VB):

VB

sinLatitude = sin(latitude * pi/180)
pixelX = ((longitude + 180) / 360) * 256 * (2^level)
pixelY = (0.5 – log((1 + sinLatitude) / (1 – sinLatitude)) / (4 * pi)) * 256 * (2^level)

- Create a polygon path using these points

C#

GraphicsPath polygonPath = new GraphicsPath();
polygonPath.AddPolygon(points);

- Create a region for the entire tile, something like this (the tile size depends on the level of detail, there is a table in the link above for tile sizes for different 'zoom levels'

C#

Region region = new Region(new Rectangle(0, 0, 256, 256));

- Exclude the area you just created.

C#

region.Exclude(polygonPath);

- Fill the region with a color. This will mask out everything outside the country borders

C#

graphics.FillRegion(Brushes.Black, region);

To make it look nicer, you may decide to draw a line using the points array to clearly mark the country border.

C#

graphics.DrawLines(
new System.Drawing.Pen(System.Drawing.Color.FromArgb(255, 255, 0, 0), 3),
points);
