EmguCV 简单图形绘制

一、圆

  public static void cvCircle(

      IntPtr img,

      System.Drawing.Point center,    //Center of the circle

      int radius,      //Radius of the circle

      MCvScalar color,  //Color of the circle

      int thickness,    if negative indicates that a filled circle has to be drawn

      Emgu.CV.CvEnum.LINE_TYPE lineType,

      int shift      //Number of fractional bits in the center coordinates and radius value

  )

  eg:

  CvInvoke.cvCircle(dst1, new Point(120, 120), 100, new MCvScalar(255, 255, 255), 3, Emgu.CV.CvEnum.LINE_TYPE.CV_AA, 0);

二、线段

  public static void cvLine(

      IntPtr img,

      System.Drawing.Point pt1,

      System.Drawing.Point pt2,

      MCvScalar color,

      int thickness,

      Emgu.CV.CvEnum.LINE_TYPE lineType,

      int shift

  )
