你们可以看到,它有变迁功能,你可以找到烟雾坐标,而不是最后解决办法,你们应该定制。

Answer 2

Ya, 可能使用。你们必须利用MouseDown Point和MouseUpPoint来拍摄图像。以下方法将显示你在银灯中抽取试金的样本。

void DrawShape(Shape MyShape, Point MyStartpoint, Point MyEndpoint)
        {
            if (CreateRectangle)
            {
                MyShape.Stroke = new SolidColorBrush(SetColor);
                MyShape.Stroke.Opacity = 0.1;
                MyShape.Fill = new SolidColorBrush(SetColor);
                MyShape.Fill.Opacity = 0;
                MyShape.StrokeThickness = 2;
            if (DrawMode)
            {
                Temp = End;
                DrawMode = false;
            }
                if (Temp.X < MyEndpoint.X && Temp.Y < MyEndpoint.Y)
                {
                    MyShape.SetValue(Canvas.LeftProperty, MyStartpoint.X);
                    MyShape.SetValue(Canvas.TopProperty, MyStartpoint.Y);
                }
                else if (Temp.X > MyEndpoint.X && Temp.Y < MyEndpoint.Y)
                {
                    double LeftX = MyStartpoint.X - (Temp.X - MyEndpoint.X);
                    MyShape.SetValue(Canvas.LeftProperty, LeftX);
                    MyShape.SetValue(Canvas.TopProperty, MyStartpoint.Y);
                }
                else if (Temp.X < MyEndpoint.X && Temp.Y > MyEndpoint.Y)
                {
                    double TopY = MyStartpoint.Y - (Temp.Y - MyEndpoint.Y);

                    MyShape.SetValue(Canvas.TopProperty, TopY);
                }
                else if (Temp.X > MyEndpoint.X && Temp.Y > MyEndpoint.Y)
                {
                    double LeftX = MyStartpoint.X - (Temp.X - End.X);
                    double TopY = MyStartpoint.Y - (Temp.Y - End.Y);
                    MyShape.SetValue(Canvas.LeftProperty, LeftX);
                    MyShape.SetValue(Canvas.TopProperty, TopY);
                }
                if (MyStartpoint.X > MyEndpoint.X)
                {
                    MyShape.Width = MyStartpoint.X - MyEndpoint.X;
                }
                else
                {
                    MyShape.Width = MyEndpoint.X - MyStartpoint.X;
                }
                if (MyStartpoint.Y > MyEndpoint.Y)
                {
                    MyShape.Height = MyStartpoint.Y - MyEndpoint.Y;
                }
                else
                {
                    MyShape.Height = MyEndpoint.Y - MyStartpoint.Y;
                }
                //Buttondown = false;
                //diagram.Children.Add(MyShape);
            }
        }
