Release Notes for iOS SDK - 10.x

10.2.11 (05/15/2024)

Fixed

  • Fixed a bug where OneDCodeDetails might be nil.

10.2.10 (04/16/2024)

Improved

  • Security update for DynamsoftBarcodeReader library and other corresponding libraries.
  • Supported multiple instances of the class CaptureVisionRouter.
  • Improved the usage count logic of the concurrent license mode.
  • Improved the experience of local cache usage when failing to connect the license server. The renewal of the local cache is optimized as well.
  • Improved the barcode decoding performance:
    • Improved the accuracy when decoding OneD & PDF417 barcodes.
    • Improved the readability of dense DataMatrix codes.

New

Breaking Changes

  • Changed the logic of the stopCapturing method.
    • DSCaptureResultReceiver will not receive results after stopCapturing is triggered with waitForRemainingTasks false.
    • Support stop capturing after the pauseCapturing method is triggered.
  • Changed the logic of the capturedResultItemTypes setting of DSSimplifiedCaptureVisionSettings:
    • If the result item types don’t match the specified template, the method updateSettings will return the error code EC_PARAMETER_VALUE_INVALID with the message “The captured result item types do not match the task configurations in the template”.
    • Based on the capturedResultItemTypes setting, the irrelevant tasks will be removed from the template.
    • The capturedResultItemTypes should include at least one of the CRIT_BARCODE, CRIT_TEXT_LINE, CRIT_DETECTED_QUAD, CRIT_NORMALIZED_IMAGE. Otherwise, the method updateSettings will return the error code EC_PARAMETER_VALUE_INVALID with the message “The captured result item types should contain at least one task result type”.
  • Refactored the DSContour class. Please view API reference - Contour class for more information.

Fixed

  • Fixed a crash bug that might happen when triggering the setNextImageToReturn method of the DSImageSourceAdapter class.
  • Fixed a bug where error messages are not output when parsing the parameter templates.
  • Fixed a misreading bug of the PDF417 barcodes on the South Carolina driver’s license.
  • Internal changes to prevent crash bugs in barcode decoding.
  • Fixed a bug where the capture might be blocked due to the network latency.
  • Fixed the bugs of usage count.
    • Count twice for a single PDF417 barcode when a code parser task is implemented on the result.
    • The barcode decoding result might not be uploaded timely.
    • Patchcode might be counted even if there is no Patchcode license item.

10.0.21 (12/12/2023)

  • Updated the internal package dependencies rules.

10.0.20 (10/26/2023)

DynamsoftBarcodeReader SDK has been revamped to integrate with DynamsoftCaptureVision (DCV) architecture, which is newly established to aggregate the features of functional products powered by Dynamsoft. The features are designed to be pluggable, customizable and interactable. In addition, the functional products share the computation so that their processing speed is much higher than working individually.

  • DynamsoftCaptureVision architecture consists of:
    • ImageSourceAdapter(ISA), the standard input interface for you to convert image data from different sources into the standard input image data. In addition, ISA incorporates an image buffer management system that allows instant access to the buffered image data.
    • CaptureVisionRouter (CVR), an engine for you to update templates, retrieve images from ISA, coordinate corresponding functional products and dispatch the results to the receivers.
    • Functional products that perform image processing, content understanding and semantic processing. The functional products are pluggable and passively called by CVR when they are required.
    • Result receiver interfaces. You can implement CapturedResultReceiver (CRR) to receive the CapturedResults that output when the processing on an image is finalized. You can also implement IntermediateResultReceiver (IRR) to get timely results from different stages of the workflow.
  • The parameter template system has been comprehensively upgraded.
    • Multiple algorithm task settings are available. You can define barcode decoding, label recognizing, document scanning and semantic processing tasks in one template file.
    • Extended the feature of the ROI system. By configuring the target ROI parameters, you can not only specify an ROI on the original image but also define the dependencies of the algorithm tasks. This feature enables you to customize the workflow when processing complex scenarios.
    • The image processing parameters are separated from the task parameters so that the template settings become more clear and concise.
  • The intermediate result system has been improved.
    • Achieved the intermediate result sharing between different functional products. The results that have the same image source and processing parameters are directly reused, which speeds up the image processing workflow. You don’t need to add any additional code to enable the intermediate result sharing. The library can recognize all the reusable results automatically based on the template file you uploaded.
    • The readability and interactivity of the intermediate results are enhanced. IntermediateResultReceiver allows you to receive up to 27 different types of Intermediate results. You can clearly read which stage of the algorithm each result is output from. In addition, IntermediateResultManager allows you to intervene in the workflows by modifying the intermediate results.

The APIs of Dynamsoft Barcode Reader are comprehensively updated. Please follow the view upgrade instructions to update your code.
