SkPath is a class in the Skia graphics library which represents a path composed of lines, curves, and other geometric shapes. One of the member functions of SkPath is countPoints(), which returns the number of points that make up the path. Here are some examples of its usage:

**Example 1:** Simple line path

In this example, we create a simple path composed of three straight lines, and then call the countPoints() function to get the number of points in the path. The answer is three, because there are three endpoints of the lines.

**Example 2:** Quadratic curve path

SkPath path; path.moveTo(0, 0); path.lineTo(10, 10); path.lineTo(20, 10); int num_points = path.countPoints(); // num_points = 3

In this example, we create a simple path composed of three straight lines, and then call the countPoints() function to get the number of points in the path. The answer is three, because there are three endpoints of the lines.

SkPath path; path.moveTo(0, 0); path.quadTo(10, 20, 20, 10); int num_points = path.countPoints(); // num_points = 2Here, we create a path consisting of a single quadratic curve. In this case, there are only two points on the curve: the start point and the end point. Therefore, countPoints() returns a value of two. The package library for Skia graphics is usually "skia" or "libskia".
