LineSegmentsUnit
The LineSegmentsUnit class represents a collection of line segments in 2D space. It is a derived class of IntermediateResultUnit.
Definition
Namespace: com.dynamsoft.core.intermediate_results
Assembly: DynamsoftCore.aar
class LineSegmentsUnit extends IntermediateResultUnit
Methods
| Methods | Description |
|---|---|
getLineSegments |
Gets an array of LineSegment objects, each representing a segment of a line detected within the image. |
getCount |
Gets the number of line segments. |
getLineSegment |
Gets the LineSegment at the specified index. |
removeAllLineSegments |
Removes all line segments. |
removeLineSegment |
Removes the line segment at the specified index. |
addLineSegment |
Adds a line segment. |
setLineSegment |
Sets the line segment at the specified index. |
Inherited Methods
The following methods are inherited from class IntermediateResultUnit.
| Method | Description |
|---|---|
clone |
Creates a copy of the intermediate result unit. |
gethashId |
Gets the hash ID of the unit. The hash ID is the unique identifier for the intermediate result unit. |
getOriginalImageHashId |
Gets the hash ID of the original image. You can use this ID to get the original image via IntermediateResultManager class. |
getOriginalImageTag |
Gets the image tag of the original image associated with this unit. |
getType |
Gets the type of the intermediate result unit, defined by the enumeration EnumIntermediateResultUnitType. |
getTransformMatrix |
Gets the transformation matrix via EnumTransformMatrixType. |
replace |
Replaces the old unit with the new unit. |
getLineSegments
Gets the array of LineSegment.
LineSegment[] getLineSegments();
Return Value
The array of LineSegment.
getCount
Gets the number of line segments.
int getCount();
Return Value
The number of line segments.
getLineSegment
Gets the LineSegment at the specified index.
LineSegment getLineSegment(int index);
Return Value
The LineSegment at the specified index.
removeAllLineSegments
Removes all line segments.
void removeAllLineSegments();
removeLineSegment
Removes the line segment at the specified index.
int removeLineSegment(int index);
Parameters
[in] index: The index of the line segment to remove.
Return Value
Returns the ErrorCode if failed. Otherwise, returns 0.
addLineSegment
Adds a line segment.
int addLineSegment(LineSegment line, Matrix matrixToOriginalImage);
Parameters

setLineSegment
Sets the line segment at the specified index.
int setLineSegment(int index, LineSegment line, Matrix matrixToOriginalImage);
Parameters
[in] index: The index of the line segment to set.
[in] line: The line segment to set.
[in] matrixToOriginalImage: The transformation matrix from the line segment to the original image.
Return Value
Returns the ErrorCode if failed. Otherwise, returns 0.
