DSMultiFrameResultCrossFilter

The DSMultiFrameResultCrossFilter class is responsible for filtering captured results.

Definition

Assembly: DynamsoftUtility.xcframework

• Objective-C
• Swift

1. @interface DSMultiFrameResultCrossFilter ()<CapturedResultFilter>
   

2. class MultiFrameResultCrossFilter: NSObject, CapturedResultFilter
   

Methods

enableLatestOverlapping

Enables or disables the to-the-latest overlapping feature of one or multiple specific result item types. This feature can sharpenly increase the read-rate performance when decoding multiple barcodes under the video streaming.

• Objective-C
• Swift

1. - (void)enableLatestOverlapping:(DSCapturedResultItemType)resultItemTypes
                     isEnabled:(BOOL)isEnabled;
   

2. func enableLatestOverlapping(resultItemTypes: DSCapturedResultItemType, isEnabled: Bool)
   

Parameters

[in] type: Specifies the result item type with DSCapturedResultItemType.

[in] enable: Bool to toggle to-the-latest overlapping on or off.

enableResultCrossVerification

Enables or disables the verification of one or multiple specific result item types.

• Objective-C
• Swift

1. - (void)enableResultCrossVerification:(DSCapturedResultItemType)resultItemType
                   isEnabled:(BOOL)isEnabled;
   

2. func enableResultCrossVerification(resultItemType: DSCapturedResultItemType, isEnabled: Bool)
   

Parameters

resultItemType: Specifies one or multiple specific result item types, which can be defined using DSCapturedResultItemType.

isEnabled: A BOOL value that indicates whether to enable the result cross verification feature.

enableResultDeduplication

Enables or disables the deduplication process for one or multiple specific result item types.

• Objective-C
• Swift

1. - (void)enableResultDeduplication:(DSCapturedResultItemType)resultItemType
                       isEnabled:(BOOL)isEnabled;
   

2. func enableResultDeduplication(resultItemType: DSCapturedResultItemType, isEnabled: Bool)
   

Parameters

resultItemType: Specifies one or multiple specific result item types, which can be defined using DSCapturedResultItemType.

Parameters

resultItemType: Specifies the result item type with DSCapturedResultItemType.

Return Value

The set interval for the specified item type.

getMaxOverlappingFrames

Get the maximum overlapping frames count for a given result item type.

• Objective-C
• Swift

1. - (NSInteger)getMaxOverlappingFrames:(DSCapturedResultItemType)resultItemType;
   

2. func getMaxOverlappingFrames(resultItemType: DSCapturedResultItemType) -> Int
   

Parameters

[in] type: Specifies the result item type with DSCapturedResultItemType.

Return Value

The maximum overlapping frame count for the overlapping.

isLatestOverlappingEnabled

Checks if to-the-latest overlapping is active for a given result item type.

• Objective-C
• Swift

1. - (BOOL)isLatestOverlappingEnabled:(DSCapturedResultItemType)resultItemTypes;
   

2. func isLatestOverlappingEnabled(resultItemType: DSCapturedResultItemType) -> Bool
   

Parameters

[in] type: Specifies the result item type with DSCapturedResultItemType.

Return Value

Boolean indicating the to-the-latest overlapping status for the specified type.

isResultDeduplicationEnabled

Checks if deduplication is active for a given result item type.

• Objective-C
• Swift

1. - (bool)isResultDeduplicationEnabled:(DSCapturedResultItemType)resultItemType;
   

2. func isResultDeduplicationEnabled(resultItemType: DSCapturedResultItemType) -> Bool
   

Parameters

resultItemType: Specifies the result item type with DSCapturedResultItemType.

Return Value

Boolean indicating the deduplication status for the specified type.

isResultCrossVerificationEnabled
