VisionPro與C# 圖像顯示十字光标

程式通過 CogRecordDisplay 顯示控件顯示視覺運作結果圖像，當我們對調試時，可能需要用到圖像中心十字對位光标。

本文通過VisionPro兩個拟合線工具，一個拟合圓工具在圖像中畫出光标，具體代碼如下：

using System.Windows.Forms;
using Cognex.VisionPro;
using Cognex.VisionPro.ToolBlock;

        /// <summary>
        /// 界面顯示十字光标
        /// </summary>
        /// <param name="cogDisplay"></param>
        /// <param name="camPixX"></param>
        /// <param name="camPixY"></param>
        private void DrawCross(CogRecordDisplay cogDisplay, double camPixX, double camPixY)
        {
            try
            {
                CogLine vLine = new CogLine();//豎線
                CogLine hLine = new CogLine();//橫線
                CogCircle CenterCircle = new CogCircle();
                double centerPixX = camPixX / 2;
                double centerPixY = camPixY / 2;
                vLine.Color = CogColorConstants.Red;
                hLine.Color = CogColorConstants.Red;
                CenterCircle.Color = CogColorConstants.Red;
                CenterCircle.CenterX = centerPixX;
                CenterCircle.CenterY = centerPixY;
                CenterCircle.Radius = 100;
                vLine.SetFromStartXYEndXY(centerPixX, 0, centerPixX, camPixY);
                hLine.SetFromStartXYEndXY(0, centerPixY, camPixX, centerPixY);
                cogDisplay.InteractiveGraphics.Clear();
                cogDisplay.InteractiveGraphics.Add(vLine, "vline", true);
                cogDisplay.InteractiveGraphics.Add(hLine, "hline", true);
            }
            catch (Exception ex)
            {

            }
        }
