The Contour<(Of <(<'T>)>)> type exposes the following members.

Constructors

  NameDescription
Public methodContour<(Of <(<'T>)>)>(MemStorage)
Create a contour using the specific storage
Public methodContour<(Of <(<'T>)>)>(Int32, MemStorage)
Create a contour using the specific seqFlag and storage
Public methodContour<(Of <(<'T>)>)>(IntPtr, MemStorage)
Craete a contour from the specific IntPtr and storage
Public methodContour<(Of <(<'T>)>)>(SEQ_ELTYPE, SEQ_KIND, SEQ_FLAG, MemStorage)
Create a contour of the specific kind, type and flag

Methods

  NameDescription
Public methodApproxPoly(Double)
Approximates one or more curves and returns the approximation result[s]. In case of multiple curves approximation the resultant tree will have the same structure as the input one (1:1 correspondence)
Public methodApproxPoly(Double, MemStorage)
Approximates one curves and returns the approximation result.
Public methodApproxPoly(Double, Int32, MemStorage)
Approximates one or more curves and returns the approximation result[s]. In case of multiple curves approximation the resultant tree will have the same structure as the input one (1:1 correspondence)
Public methodClear
Removes all elements from the sequence. The function does not return the memory to the storage, but this memory is reused later when new elements are added to the sequence. This function time complexity is O(1).
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodDistance
Determines the distance from the point to the contour
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Protected methodFinalize
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetConvexHull(ORIENTATION)
Get the convex hull of this point sequence, the resulting convex hull use the same storage as the current sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodGetConvexHull(ORIENTATION, MemStorage)
Get the convex hull of this point sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodGetConvexityDefacts
Finds all convexity defects of the input contour and returns a sequence of the CvConvexityDefect structures.
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodGetEnumerator
return an enumerator of the elements in the sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodGetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
Public methodGetMinAreaRect()()()()
Get the minimum area rectangle for this point sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodGetMinAreaRect(MemStorage)
Get the minimum area rectangle for this point sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodGetMoments
Get the moments for this point sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodInContour
Determines whether the point is inside contour, outside, or lies on an edge (or coinsides with a vertex)
(Overrides Seq<(Of <(<'T>)>)>..::..InContour(PointF).)
Public methodInsert
Inserts element in sequence middle
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodMatchShapes
Compare the shape of the current contour with objectToMatch
(Inherited from Seq<(Of <(<'T>)>)>.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodPop
Pop an element from the back of the sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodPopFront
Pop an element from the front of the sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodPopMulti
Pop multiple elements from the sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodPush
Push the data to the sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodPushFront
Push the data to the sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodPushMulti
Push multiple elements to the sequence
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodRemoveAt
Removes element from sequence middle
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodSlice
Creates a sequence that represents the specified slice of the input sequence. The new sequence either shares the elements with the original sequence or has own copy of the elements. So if one needs to process a part of sequence but the processing function does not have a slice parameter, the required sub-sequence may be extracted using this function
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodToArray
Convert this sequence to array
(Inherited from Seq<(Of <(<'T>)>)>.)
Public methodToString
Returns a String that represents the current Object.
(Inherited from Object.)

Fields
