7.2.0-beta.1​

Released: March 12, 2025

Bug Fixes​

  • Removed optional dependency on OpenGL. Most configurations were already running without OpenGL prior to this release. As of 7.2, remaining configurations that depend on OpenGL were fully removed.

7.1.2​

Released: March 13, 2025

No updates for this framework in this release.

7.1.1​

Released: March 7, 2025

Bug Fixes​

  • Fixed sc_recognition_context_release to abort potentially still in-progress background set up of the barcode scanner if sc_barcode_scanner_wait_for_setup_completed was not called explicitly.

7.1.0​

Released: February 21, 2025

New Features​

  • Added the following new barcode scanner presets:
    • SC_PRESET_HIGH_EFFORT to achieve the best accuracy by spending more resources.
    • SC_PRESET_SINGLE_CODE_HAND_HELD to enable smart single code scanning.
  • sc_barcode_scanner_settings_set_code_duplicate_filter() has been extended to accept -2 (SC_DUPLICATE_FILTER_DEFAULT) to indicate that an application-specific duplicate filter should be used. -2 is the new default and is currently identical to 0 (duplicate filtering disabled).
    • New constants SC_DUPLICATE_FILTER_DEFAULT and SC_DUPLICATE_FILTER_OFF were added to indicate the intent of these values more clearly.
  • Updated the package to no longer embed required resources into libscanditsdk.so and instead load them from /usr/share/scanditsdk/resources.

Performance Improvements​

  • We’ve increased the scan rate of 10% on our datasets of QR codes with high perspective distortion (so scanned at high angles). This is particularly important for cases such as receiving boxes or scanning shelf labels.
  • Improved the barcode detection and tracking robustness of ScObjectTracker.

Behavioral Changes​

  • After further improving the scanning speed on color-inverted QR and MicroQR codes, these variations can now be scanned without having to set any specific setting (as opposed to before), offering a better experience to developers.

7.0.2​

Released: January 20, 2025

Bug Fixes​

  • Resolved a rare issue where a race condition during the deconstruction of MatrixScan Data Capture views could lead to invalid memory access.

7.0.1​

Released: December 19, 2024

No updates for this framework in this release.

7.0.0​

Released: November 29, 2024

New Features / Performance Improvements​

  • This update increases the Linux SDK libc version requirements from version 2.27 to 2.31. Ubuntu 18.04 and Debian/GNU Linux 10 are no longer supported.
  • The versioning of the Linux SDK has been aligned with the versioning of the Scandit DataCapture SDK. On Linux, 6.x is skipped and the version is updated from 5.x and 7.x directly.

The C API has been cleaned up and streamlined. If you migrate your code from version 5.x to 7.x you need to adjust the following interface changes.

  • Recognition Context:
    • Removed deprecated ScContextStatusFlag: SC_RECOGNITION_CONTEXT_STATUS_LICENSE_FILE_EXPIRED, SC_RECOGNITION_CONTEXT_STATUS_LICENSE_FILE_IO_ERROR, SC_RECOGNITION_CONTEXT_STATUS_LICENSE_VALIDATION_FAILED, SC_RECOGNITION_CONTEXT_STATUS_LICENSE_VALIDATION_FAILED_400
    • Removed deprecated recognition context function sc_recognition_context_set_geographical_location.
  • ScBarcodeScanner:
    • Replaced symbology enums SC_SYMBOLOGY_EAN13 and SC_SYMBOLOGY_UPCA by SC_SYMBOLOGY_EAN13_UPCA. EAN13 and UPCA codes are now represented and configured through the same symbology. If you need to distinguish between UPCA and EAN13, you will need to check for the first digit, or use the remove_leading_upca_zero symbology extension and check the length of the returned data string.
    • Removed the SC_SYMBOLOGY_UPCA symbology extension remove_leading_zero. Use the SC_SYMBOLOGY_EAN13_UPCA extension remove_leading_upca_zero instead.
    • Removed functionality related to caching of codes in the barcode scanner session. To obtain the results, retrieve them through sc_barcode_scanner_session_get_newly_recognized_codes before processing the next frame. Removed the two functions sc_barcode_scanner_settings_set_code_caching_duration, sc_barcode_scanner_settings_get_code_caching_duration and JSON settings field codeCachingDuration.
    • Removed all ScBarcodeScannerSettings presets: SC_PRESET_ENABLE_RETAIL_SYMBOLOGIES, SC_PRESET_ENABLE_VIN_DECODING, SC_PRESET_ENABLE_SSCC_DECODING, SC_PRESET_ENABLE_SINGLE_FRAME_MODE. New presets will be introduced in upcoming releases.
    • Replaced sc_barcode_scanner_settings_get_property and sc_barcode_scanner_settings_set_property functions that allowed to get/set scanner integer properties by sc_barcode_scanner_settings_get_properties/sc_barcode_scanner_settings_get_properties_const to access the settings property collection.
    • Introduced ScPropertyCollection.h header allowing to get/set property values of the generic property collection.
  • ScBarcodeGenerator:
    • The SC_SYMBOLOGY_EAN13_UPCA code generator no longer accepts UPCA input strings without leading zero character. 12 digits inputs are now interpreted as EAN13 data with a missing checksum.
  • ScParser:
    • Moved and renamed parser-related headers from include/Scandit/Parser/ to include/Scandit:
    • Renamed SpParser.h to ScParser.h
      • Renamed SpParser to ScParser
      • Renamed SpParserType to ScParserType
      • Renamed SP_PARSER_TYPE_* enum entries to SC_PARSER_TYPE_*
      • Renamed sp_parser_* functions to sc_parser_*
    • Renamed SpParserResult.h to ScParserResult.h
      • Renamed SpParserResult to ScParserResult
      • Renamed SpField to ScField
      • Renamed sp_parser_result_* functions to sc_parser_result_*
    • Removed SpParserCommon.h:
      • Use ScBool instead of SpBool
      • Use ScByteArray instead of SpData
      • Removed unused sp_data_free
  • ScCommon:
    • Updated ScByteArray-related api:
      • Removed deprecated ScByteArray fields data, c_str, length.
      • Updated functions returning ScByteArray such that the returned array size does not include string null terminator.
    • Removed deprecated ScData struct alias:
      • ScByteArray should be used directly instead.
    • Removed deprecated sc_data_free function. sc_byte_array_free should be used instead.
    • Updated sc_*_free functions to align their behavior, such that calling sc_*_free on any object more than once is undefined behavior that would end up in double free.
  • ScImageDescription:
    • Added sc_image_description_get_planes_count function to query number of separate planes in an image according to its layout.
    • Added sc_image_description_get_plane_offset/sc_image_description_get_plane_row_bytes functions to query plane information by index of the plane in a buffer.
    • Removed sc_image_description_get_first_plane_offset/sc_image_description_get_first_plane_row_bytes, use sc_image_description_get_plane_offset instead.
    • Removed sc_image_description_get_second_plane_offset/sc_image_description_get_second_plane_row_bytes, use sc_image_description_get_plane_offset instead.
    • Removed sc_image_description_get_memory_size/sc_image_description_set_memory_size. There is no more need to set the overall memory size.
  • ScObjectTracker:
    • The configuration of barcode scanner settings for use with the ScObjectTracker has been moved to a dedicated API: sc_object_tracker_apply_scanner_settings. It is no longer necessary to instantiate an ScBarcodeScanner to use the ScObjectTracker.
    • Replaced the callback-based tracking results API ScObjectTrackerCallbacks by a session object ScObjectTrackerSession.
  • The Python API was adjusted according to the new C API. In addition the following changes were made:
    • Removed all deprecated redundant SC_CODE_DIRECTION_* constants. Use sc.CODE_DIRECTION_* instead.
    • Removed all deprecated redundant SC_IMAGE_LAYOUT_* constants. Use sc.IMAGE_LAYOUT_* instead.
    • Removed sc.IMAGE_LAYOUT_NV16 constant. Use sc.IMAGE_LAYOUT_NV16_U8 instead.
    • Removed all deprecated redundant SC_CAMERA_* constants. Use sc.CAMERA_* instead.
    • Removed all deprecated redundant SC_CODE_LOCATION_* constants. Use sc.CODE_LOCATION_* instead.
  • Introduced support for Swiss Post proprietary, UPU 4 State based, postal symbology. It's disabled by default and can be enabled activating the UPU 4-State symbology extension swiss_post_decoding.

Bug Fixes​

  • Improvements for decoding blurry 1d linear codes.
  • Improved tracking of 1D codes that are horizontally aligned.
  • Added remove_delimiter_data extension to the Codabar symbology. This extension is off by default.
  • Fixed ScCamera python bindings querying stepwise camera mode resolutions.
  • Fixed sc_camera_get_frame to not hang after restarting camera stream.
  • Fixed Shift-JIS encoding classification for raw byte data in 2d barcodes
