如何使用C＃绘制/绘制失败的箭头

问题描述

Windows窗体。

我有一个绘制箭头的现有代码。现在我需要一个带X的新箭头（代表失败的箭头）。感谢任何帮助。



我尝试过：



double xAxis = arrow.StartCoordinate.x;

double yAxis = arrow.StartCoordinate.y;

double xeAxis = arrow.EndCoordinate.x;

double yeAxis = arrow.EndCoordinate.y;

double lineCentre = arrowLine.BBox.AsRectangleF.Width / 8;

Point3d point1 = new Point3d（xAxis +（lineCentre + lineCentre） ），yAxis + lineCentre）;

Point3d point2 = new Point3d（xeAxis - （lineCentre + lineCentre），yeAxis - lineCentre）;

Point3d point3 = new Point3d（xAxis + （lineCentre + lineCentre），yAxis - lineCentre）;

Point3d point4 = new Point3d（xeAxis - （lineCentre + lineCentre），yeAxis + lineCentre）;

Windows form.
i have a existing code that draw's arrow. now i need to have a new arrow with X (which represents failed arrow). Any help is appreciated.

What I have tried:

double xAxis = arrow.StartCoordinate.x;
double yAxis = arrow.StartCoordinate.y;
double xeAxis = arrow.EndCoordinate.x;
double yeAxis = arrow.EndCoordinate.y;
double lineCentre = arrowLine.BBox.AsRectangleF.Width/8;
Point3d point1 = new Point3d(xAxis + ( lineCentre + lineCentre ), yAxis + lineCentre );
Point3d point2 = new Point3d(xeAxis - (lineCentre + lineCentre ), yeAxis - lineCentre);
Point3d point3 = new Point3d(xAxis + (lineCentre + lineCentre ), yAxis - lineCentre);
Point3d point4 = new Point3d(xeAxis - ( lineCentre + lineCentre ), yeAxis + lineCentre);
