ContoursUnit

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

Definition

Namespace: com.dynamsoft.core.intermediate_results

Assembly: DynamsoftCore.aar

class ContoursUnit: IntermediateResultUnit

Methods

Methods Description
getContours Gets the contour array of the unit.
setContours Sets the contour array for the unit.
getHierarchies Gets the contour hierarchies as an array of Vector4 objects.

Inherited Methods

The following methods are inherited from class [IntermediateResultUnit]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html).

Method Description
[clone]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#clone) Creates a copy of the intermediate result unit.
[gethashId]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#gethashid) Gets the hash ID of the unit. The hash ID is the unique identifier for the intermediate result unit.
[getOriginalImageHashId]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#getoriginalimagehashid) Gets the hash ID of the original image. You can use this ID to get the original image via IntermediateResultManager class.
[getOriginalImageTag]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#getoriginalimagetag) Gets the image tag of the original image associated with this unit.
[getType]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#gettype) Gets the type of the intermediate result unit, defined by the enumeration [EnumIntermediateResultUnitType]({{ site.dcv_enumerations }}core/intermediate-result-unit-type.html?lang=android).
[getTransformMatrix]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#gettransformmatrix) Gets the transformation matrix via EnumTransformMatrixType.
[replace]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#replace) Replaces the old unit with the new unit.

getContours

Gets the contour array of the unit.

Contour[] getContours()

Return Value

The array of Contour objects.

setContours

int setContours(Contour[] contours, Vector4[] hierarchies, Matrix matrixToOriginalImage);

Parameters

contours: The array of Contour objects.

hierarchies: The contour hierarchies as an array of Vector4 objects.

matrixToOriginalImage: The transformation matrix of the original image.

Return Value

Returns the ErrorCode if failed. Otherwise, returns 0.

getHierarchies

Gets the contour hierarchies as an array of Vector4 objects.

Vector4[] getHierarchies()

Return Value

The contour hierarchies as an array of Vector4 objects.
