DSIntermediateResultUnit

The DSIntermediateResultUnit class represents an intermediate result unit used in image processing. It is an abstract base class with multiple subclasses, each representing a different type of unit such as pre-detected regions, localized barcodes, decoded barcodes, localized text lines, binary image, gray image, etc.

Definition

Assembly: DynamsoftCore.framework

>- Objective-C >- Swift > >1. ```objc @interface DSIntermediateResultUnit : NSObject ``` 2. ```swift class IntermediateResultUnit : NSObject ```

Attributes

Attributes Type Description
hashId NSString * The hash ID of the unit.
originalImageHashId NSString * The hash ID of the original image. You can use this ID to get the original image via IntermediateResultManager class.
originalImageTag DSImageTag * The image tag of the original image.
type DSIntermediateResultUnitType The type of the intermediate result unit.

Methods

Method Description
getTransformMatrix Gets the transformation matrix via DSTransformMatrixType.
clone Creates a copy of the intermediate result unit.

hashId

The hash ID of the unit.

>- Objective-C >- Swift > >1. ```objc @property(nonatomic, copy, readonly) NSString *hashId; ``` 2. ```swift var hashId: String? { get } ```

originalImageHashId

The hash ID of the original image. You can use this ID to get the original image via IntermediateResultManager class.

>- Objective-C >- Swift > >1. ```objc @property(nonatomic, copy, readonly) NSString *originalImageHashId; ``` 2. ```swift var originalImageHashId: String? { get } ```

originalImageTag

The image tag of the original image.

>- Objective-C >- Swift > >1. ```objc @property(nonatomic, strong, readonly, nullable) DSImageTag *originalImageTag; ``` 2. ```swift var originalImageTag: ImageTag? { get } ```

type

The type of the intermediate result unit.

>- Objective-C >- Swift > >1. ```objc @property(nonatomic, assign, readonly) EnumIntermediateResultUnitType type; ``` 2. ```swift var type: EnumIntermediateResultUnitType { get } ```

getTransformMatrix

Gets the transformation matrix via DSTransformMatrixType.

>- Objective-C >- Swift > >1. ```objc -(CGAffineTransform)getTransformMatrix:(DSTransformMatrixType)matrixType; ``` 2. ```swift func getTransformMatrix(DSTransformMatrixType matrixType) -> CGAffineTransform ```

Parameters

[in] matrixType: The transform matrix type.

Return Value

The corresponding transformation matrices are as follows:

  • local image to original image
  • original image to local image
  • rotated image to original image
  • original image to rotated image

clone

Creates a copy of the intermediate result unit.

>- Objective-C >- Swift > >1. ```objc - (DSIntermediateResultUnit*)clone; ``` 2. ```swift func clone() -> IntermediateResultUnit ```

Return Value

A copy of the intermediate result unit.
