cvSampleLine Method (image, pt1, pt2, buffer, connectivity)

www.emgu.com/wiki

Implements a particular case of application of line iterators. The function reads all the image points lying on the line between pt1 and pt2, including the ending points, and stores them into the buffer

Declaration Syntax

Visual Basic

Visual C++

public static int cvSampleLine(
	IntPtr image,
	MCvPoint pt1,
	MCvPoint pt2,
	IntPtr buffer,
	int connectivity
)

Public Shared Function cvSampleLine ( _
	image As IntPtr, _
	pt1 As MCvPoint, _
	pt2 As MCvPoint, _
	buffer As IntPtr, _
	connectivity As Integer _
) As Integer

public:
static int cvSampleLine(
	IntPtr image, 
	MCvPoint pt1, 
	MCvPoint pt2, 
	IntPtr buffer, 
	int connectivity
)

Parameters

image (IntPtr): Image to sample the line from

pt1 (MCvPoint): Starting the line point.

pt2 (MCvPoint): Ending the line point

buffer (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 (Int32): The line connectivity, 4 or 8
