Namespace: Emgu.CV
Assembly: Emgu.CV (in Emgu.CV.dll) Version: 2.4.2.1777 (2.4.2.1777)

Syntax

C#
public static Rectangle cvBoundingRect(
	IntPtr points,
	int update
)
Visual Basic
Public Shared Function cvBoundingRect ( _
	points As IntPtr, _
	update As Integer _
) As Rectangle
Visual C++
public:
static Rectangle cvBoundingRect(
	IntPtr points, 
	int update
)

Parameters

points
Type: System..::..IntPtr
Either a 2D point set, represented as a sequence (CvSeq*, CvContour*) or vector (CvMat*) of points, or 8-bit single-channel mask image (CvMat*, IplImage*), in which non-zero pixels are considered
update
Type: System..::..Int32
The update flag. Here is list of possible combination of the flag values and type of contour: points is CvContour*, update=0: the bounding rectangle is not calculated, but it is read from rect field of the contour header. points is CvContour*, update=1: the bounding rectangle is calculated and written to rect field of the contour header. For example, this mode is used by cvFindContours. points is CvSeq* or CvMat*: update is ignored, the bounding rectangle is calculated and returned.

Return Value

The up-right bounding rectangle for 2d point set
