The CContoursUnit class represents a unit that contains contours as intermediate results. It is derived from the CIntermediateResultUnit class.

Definition

Namespace: dynamsoft::intermediate_results

Assembly: DynamsoftCore

class CContoursUnit : public CIntermediateResultUnit

Method	Description
`GetCount`	Gets the number of contours in the unit.
`GetContour`	Gets the contour at the specified index.

The following methods are inherited from class CIntermediateResultUnit.

Method	Description
`GetHashId`	Gets the hash ID of the unit.
`GetOriginalImageHashId`	Gets the hash ID of the original image.
`GetOriginalImageTag`	Gets the image tag of the original image.
`GetType`	Gets the type of the intermediate result unit.
`Clone`	Creates a copy of the intermediate result unit.
`SetHashId`	Sets the hash ID of the unit.
`SetOriginalImageHashId`	Sets the hash ID of the original image.
`SetOriginalImageTag`	Sets the image tag of the original image.
`Retain`	Increases the reference count of the unit.
`Release`	Decreases the reference count of the unit.
`GetTransformMatrix`	Gets the transformation matrix via `TransformMatrixType`.
`SetTransformMatrix`	Sets the transformation matrix via `TransformMatrixType`.

Gets the number of contours in the unit.

virtual int GetCount() const;

Return value

Returns the number of contours in the unit.

Gets the contour at the specified index.

virtual int GetContour(int index, CContour* contour) const;

Parameters

[in] index The index of the contour to get.

[in, out] contour A pointer to a CContour object that will be filled with the contour data.

Return value

Returns 0 if successful, or an error code if the contour could not be retrieved.

Note: The caller of this method is responsible for allocating memory for the contour pointer.
