using IronSoftware.Drawing; using System; PointF pointFloat = new PointF(22.2f, 25.7f); // Offset method adds offset value to the original point. pointFloat.Offset(-10, 10); // Check new x coordinate value after offset Console.WriteLine(pointFloat.X); // Check new y coordinate value after offset Console.WriteLine(pointFloat.Y);

偏移

This example should guide you on how to adjust coordinates in the PointF or Point class using the Offset() method.

This method is available in both the Point and PointF classes, and it is mainly used to programmatically move or adjust the coordinates of a certain point. The Offset() method modifies the current x and y coordinates of a point without returning a new Point object.

To use the Offset() method, simply call it with two integer values as arguments on a Point or PointF object. The first argument will offset the Point's x coordinate, while the second argument will offset the Point's y-coordinate. This method also accepts negative values as arguments.

Instantiating a PointF object: The PointF class is used to represent points with floating-point numbers for x and y coordinates. In this example, the point is initialized at (10.5, 20.5).
Calling the Offset() method: The method adjusts the coordinates of the PointF object by the specified offset values. Specifically, point.Offset(-5.0f, 10.0f); will move the point's x coordinate by -5.0 and its y coordinate by +10.0.
Console output: The initial and new coordinates of the PointF object are printed to the console, demonstrating the effect of the Offset() method.
