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. @interface DSIntermediateResultUnit : NSObject
   

2. 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. @property(nonatomic, copy, readonly) NSString *hashId;
   

2. 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. @property(nonatomic, copy, readonly) NSString *originalImageHashId;
   

2. var originalImageHashId: String? { get }
   

originalImageTag

The image tag of the original image.

• Objective-C
• Swift

1. @property(nonatomic, strong, readonly, nullable) DSImageTag *originalImageTag;
   

2. var originalImageTag: ImageTag? { get }
   

type

The type of the intermediate result unit.

• Objective-C
• Swift

1. @property(nonatomic, assign, readonly) EnumIntermediateResultUnitType type;
   

2. var type: EnumIntermediateResultUnitType { get }
   

getTransformMatrix

Gets the transformation matrix via DSTransformMatrixType.

• Objective-C
• Swift

1. -(CGAffineTransform)getTransformMatrix:(DSTransformMatrixType)matrixType;
   

2. 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. - (DSIntermediateResultUnit*)clone;
   

2. func clone() -> IntermediateResultUnit
   

Return Value

A copy of the intermediate result unit.

Code Snippet

• Objective-C
• Swift

1. DSIntermediateResultUnit *unitCopy = [unit clone];
   

2. let unitCopy = unit.clone()
