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
)
