cvLine Method (img, pt1, pt2, color, thickness, lineType, shift)
NamespacesEmgu.CVCvInvokecvLine(IntPtr, MCvPoint, MCvPoint, MCvScalar, Int32, LINE_TYPE, Int32)

www.emgu.com/wiki
Draws the line segment between pt1 and pt2 points in the image. The line is clipped by the image or ROI rectangle. For non-antialiased lines with integer coordinates the 8-connected or 4-connected Bresenham algorithm is used. Thick lines are drawn with rounding endings. Antialiased lines are drawn using Gaussian filtering.

Parameters
img (IntPtr)
The image
pt1 (MCvPoint)
First point of the line segment
pt2 (MCvPoint)
Second point of the line segment
color (MCvScalar)
Line color
thickness (Int32)
Line thickness.
lineType (LINE_TYPE)
Type of the line: 8 (or 0) - 8-connected line. 4 - 4-connected line. CV_AA - antialiased line.
shift (Int32)
Number of fractional bits in the point coordinates
