Opencv Code-for-drawing-a-Line-c++

This opencv tutorial is about drawing a Line:

Syntax:

void line(Mat& img, Point pt1, Point pt2, const Scalar& color, int thickness=1, int lineType=8, int shift=0)

Parameters:

img – Image.

pt1 – First point of the line segment.

pt2 – Second point of the line segment.

color – Line color.

thickness – Line thickness.

lineType – Type of the line:

8 (or omitted) - 8-connected line.

4 - 4-connected line.

CV_AA - antialiased line.

shift – Number of fractional bits in the point coordinates.

Here is the opencv code for drawing a line:

//Opencv Code for drawing a Line
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace cv;
 
int main( )
{    
  // Create black empty images
  Mat image = Mat::zeros( 400, 400, CV_8UC3 );
   
  // Draw a line 
  line( image, Point( 15, 20 ), Point( 70, 50), Scalar( 110, 220, 0 ),  2, 8 );
  imshow("Image",image);
 
  waitKey( 0 );
  return(0);
}
