getLogicLines

Get an array of LineSegment as the logic lines.

Objective-C
Swift

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

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

Return Value

Returns an array of LineSegment as the logic lines.

getCount

Gets the number of logic lines in the unit.

Objective-C
Swift

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

Return Value

Returns the number of logic lines in the unit.

getLogicLine

Gets a logic line at the specified index.

Objective-C
Swift

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

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

Parameters

index The index of the logic line.

Return Value

Returns a reference to the LineSegment object at the specified index.

removeAllLogicLines

Removes all logic lines.

Objective-C
Swift

```
-(void)removeAllLogicLines;
```
```
func removeAllLogicLines()
```

removeLogicLine

Removes the logic line at the specified index.

Objective-C
Swift

-(NSInteger)removeLogicLine:(NSInteger)index;

func removeLogicLine(_ index: Int) -> Int

Parameters

index The index of the logic line to remove.

Return Value

Returns 0 if successful, otherwise returns a negative value.

addLogicLine

Adds a logic line.

Objective-C
Swift

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

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

Parameters

logicLine The logic line to add.

matrixToOriginalImage The matrix to the original image (3x3 matrix).

Return Value Returns 0 if successful, otherwise returns a negative value.

setLogicLine

Sets the logic line at the specified index.

Objective-C
Swift

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

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

Parameters

index The index of the logic line to set.

logicLine The logic line to set.

matrixToOriginalImage The matrix to the original image (3x3 matrix).

Return Value

Returns 0 if successful, otherwise returns a negative value.
