DSShortLinesUnit

The DSShortLinesUnit class extends the DSIntermediateResultUnit class and represents a unit of intermediate result specifically for short lines.

Definition

Assembly: DynamsoftCaptureVisionBundle.xcframework

Objective-C
Swift

@interface DSShortLinesUnit: DSIntermediateResultUnit

class ShortLinesUnit: IntermediateResultUnit

Methods

Method	Description
`getShortLines`	Gets an array of `DSLineSegment` objects, each representing a short line detected within the image.
`getCount`	Returns the number of short lines in this unit.
`getShortLine`	Returns the short line at the specified index.
`removeAllShortLines`	Removes all the short lines in this unit.
`removeShortLine`	Removes the short line at the specified index.
`addShortLine`	Adds a short line to this unit.
`setShortLine`	Sets the short line at the specified index.

Inherited Methods

The following methods are inherited from class IntermediateResultUnit.

Method	Description
`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 associated with this unit.
`getOriginalImageTag`	Gets the tag associated with the original image.
`getType`	Gets the type of the intermediate result unit, defined by the enumeration `IntermediateResultUnitType`.
`getTransformMatrix`	Gets the transformation matrix via `DSTransformMatrixType`.
`clone`	Creates a copy of the intermediate result unit.
`replace`	Replaces the content of the intermediate result unit.

getShortLines

Gets an array of DSLineSegment objects, each representing a short line detected within the image.

Objective-C
Swift

-(nullable NSArray<DSLineSegment*>*)getShortLines;

```
func getShortLines() -> [LineSegment]?
```

Return Value

An array of DSLineSegment objects.

getCount

Returns the number of short lines in this unit.

Objective-C
Swift

```
-(NSInteger)getCount;
```
```
func getCount() -> Int
```

Return Value

NSInteger as the number of short lines in this unit.

getShortLine

Returns the short line at the specified index.

Objective-C
Swift

-(nullable DSLineSegment *)getShortLine:(NSInteger)index;

func getShortLine(_ index: Int) -> LineSegment?

Parameters

index: The index of the short line.

Return Value

A DSLineSegment object as the short line at the specified index.

removeAllShortLines

Removes all the short lines in this unit.

Objective-C
Swift

```
-(void)removeAllShortLines;
```
```
func removeAllShortLines()
```

removeShortLine

Removes the short line at the specified index.

Objective-C
Swift

-(void)removeShortLine:(NSInteger)index;

```
func removeShortLine(_ index: Int)
```

Parameters

index: The index of the short line.

addShortLine

Adds a short line to this unit.

Objective-C
Swift

-(NSInteger)addShortLine:(DSLineSegment*)line
   matrixToOriginalImage:(CGAffineTransform)matrixToOriginalImage;

func addShortLine(_ line: LineSegment, matrixToOriginalImage: CGAffineTransform) -> Int

Parameters

line: A DSLineSegment object as the short line to be added.

matrixToOriginalImage: A CGAffineTransform object as the transformation matrix from the original image to the image in this unit.

Return Value

Returns the ErrorCode if failed. Otherwise, returns 0.

setShortLine

Sets the short line at the specified index.

Objective-C
Swift

-(NSInteger)setShortLine:(NSInteger)index
                line:(DSLineSegment*)line
   matrixToOriginalImage:(CGAffineTransform)matrixToOriginalImage;

func setShortLine(_ index: Int, line: LineSegment, matrixToOriginalImage: CGAffineTransform) -> Int

Parameters

index: The index of the short line.

line: A DSLineSegment object as the short line to be set.

matrixToOriginalImage: A CGAffineTransform object as the transformation matrix from the original image to the image in this unit.

Return Value

Returns the ErrorCode if failed. Otherwise, returns 0.
