Gets the approximate area enclosed by an SKPath instance by comparing its total bounded area to the percentage of evenly-distributed points that are "contained" within the path.

GetEnclosedArea.cs

internal static float GetEnclosedArea(this SKPath path)
{
    SKRect bounds = path.TightBounds;
    var boundedArea = bounds.Width * bounds.Height;
    var totalPoints = 10000;
    var enclosedPoints = 0;

    for (float x = bounds.Left; x < bounds.Right; x += bounds.Width / (float)Math.Sqrt(totalPoints))
    {
        for (float y = bounds.Top; y < bounds.Bottom; y += bounds.Height / (float)Math.Sqrt(totalPoints))
        {
            if (path.Contains(x, y))
            {
                enclosedPoints++;
            }
        }
    }

    var enclosedAreaRatio = enclosedPoints / totalPoints;

    return enclosedAreaRatio * boundedArea;
