Parameters

image
Type: System..::..IntPtr
Image to sample the line from
pt1
Type: System.Drawing..::..Point
Starting the line point.
pt2
Type: System.Drawing..::..Point
Ending the line point
buffer
Type: System..::..IntPtr
Buffer to store the line points; must have enough size to store max( |pt2.x-pt1.x|+1, |pt2.y-pt1.y|+1 ) points in case of 8-connected line and |pt2.x-pt1.x|+|pt2.y-pt1.y|+1 in case of 4-connected line
connectivity
Type: Emgu.CV.CvEnum..::..CONNECTIVITY
The line connectivity, 4 or 8
