使用C＃中的图形的多边形 [英] Polygon using graphics in C#

问题描述

这是我创建多边形的代码。

我被要求绘制偏移多边形。

如果用户在文本框中输入50，那么多边形应该是随着输入的扩展绘制

各方面。



这是我的代码

Here is my code to create polygon.
I was asked to draw an offset polygon.
If a user enters "50" in text box then a polygon should be drawn with extension of input
in all sides.

Here is my code

Brush drawing_brush = new SolidBrush(Color.Red);

Brush drawing_brush1 = new SolidBrush(Color.Blue);

//Creating Pen

Pen drawing_pen = new Pen(drawing_brush, 2);
Pen drawing_pen1 = new Pen(drawing_brush1, 2);


// Initiating Graphics


Graphics Draw = this.CreateGraphics();



//int x=300;
//int y=300;


int x = Convert.ToInt32(Width.Text);
int y = Convert.ToInt32(Height.Text);

//Points Initialization

Point P1 = new Point(x, y);
Point P2 = new Point(x + 100, y);
Point P3 = new Point(x + 100, y + 100);
Point P4 = new Point(x, y + 100);


Point[] P = { P1, P2, P3, P4 };
Draw.DrawPolygon(drawing_pen, P);


Point Q1 = new Point(x - 10, y - 10);
Point Q2 = new Point(x + 110, y - 10);
Point Q3 = new Point(x + 110, y + 110);
Point Q4 = new Point(x - 10, y + 110);
Point[] Q = { Q1, Q2, Q3, Q4 };



Draw.DrawPolygon(drawing_pen1, Q);

推荐答案

你可以参考这个



绘图根据对所述输入一个多边形-坐标 [ ^ ]

You can refer this

drawing-a-polygon-according-to-the-input-coordinates[^]

是的，例如， Graphics 类提供 DrawPolygon [ ^ ]方法。您可以要求用户输入所需的点，然后使用此方法执行任务。

Yes, for instance, the Graphics class provides the DrawPolygon[^] method. You could ask the user to input the required points and then use such method to perform the task.
