EBW8PathVector Class

Vector objects are used to store 1-dimensional data.

Remarks

Using vectors is very similar to using 1-dimensional arrays, except that the size can vary at runtime. Memory allocation is handled internally.

  • To create a vector, use its constructor.
  • To fill a vector with values, first empty it, using the EVector::Empty member, and then add elements one at time at the tail by calling the EBW8PathVector::AddElement member.
  • To access a vector element, either for reading or writing, use the [] operator.
  • To inquire for the current number of elements, use member EVector::NumElements.

Base Class:EVector

Namespace: Euresys::Open_eVision

License(s): Any

Constructors

Constructs a vector.

Properties

Pointer to the vector data.

Flag indicating whether the shape built with EasyImage::Contour must be closed or not.

Methods

Appends (adds at the tail) an element to the vector.

Draws the path.

By default, the path is drawn by connecting the centers of all the pixels in the path. Using the drawOption argument, you can also connect all the top left corners of the pixels (EPathVectorDrawOption_TopLeft) in the path or fill all the pixels in the path (EPathVectorDrawOption_Fill).

Draws the path vector as the closed contour of an object In a general content, the term object should be understood with the meaning of a class instance. In EasyObject, an object is a maximally-sized area of adjacent connected pixels belonging to the layer foreground. or a blob Synonym of object.. The contour mode used to compute the path must be passed as argument to draw the contour correctly. This method only supports the closed contour modes EContourMode.ClockwiseAlwaysClosed and EContourMode.AnticlockwiseAlwaysClosed.

This method is deprecated.

Returns the vector element at the given index.

Gives access to the vector element at the given index.

Copies all the data from another EBW8PathVector object into the current EBW8PathVector object

Modifies the vector element at the given index by the given value.
