Barcode Xpress for Node.js v13.9

Barcode Xpress for Node.js v13.9 introduces the following:

13.9 New Features and Improvements

Added a RESTful API for barcode scanning Please refer to the Barcode Scanner REST API topics for more information and examples on how to use the API.
QR Code decoding. Improved decoding of damaged QR Code barcodes that have a noise line going through the locator pattern.

Addressed a memory leak issue when Barcode Xpress is used in a multithreaded application and the additionalReadingPass parameter is set to true.

Added new topics for the Barcode Scanner REST API, including how to get started and use the code examples.

Barcode Xpress for Node.js v13.8 introduces the following:

Code 39 decoding. Improved decoding of damaged Code 39 barcodes that have one of the bars split by a noise line.

Barcode Xpress for Node.js v13.7 introduces the following:

Barcode Xpress for Node.js v13.6 introduces the following:

QR Code decoding. Improved ability to decode QR Codes with interior distortion.

Added a new "Is this page helpful?" question to the bottom of each page, allowing you to send "Yes" or "No" feedback with a single click.

Barcode Xpress for Node.js v13.5 introduces the following:

Barcode Xpress now detects Micro QR barcodes. With this release you can now recognize the four versions of Micro QR codes: M1, M2, M3, and M4. For more details, refer to the Micro QR topic in the help.
New Barcode Xpress sample on GitHub - We’ve published a new sample on GitHub. This sample is deliberately minimal, designed to give developers a clear, concise example of how to get started with Barcode Xpress in a few minutes.

Addressed rare intermittent issue where Barcode Xpress wasn't able to detect any barcodes on color images.
Addressed an intermittent issue when Barcode Xpress incorrectly calculated the module width for the Data Matrix barcode with distorted timing patterns.
Addressed an issue where Barcode Xpress would sometimes discard decoded Aztec Barcodes if other 2D barcode types were selected.

We reorganized the documentation so you can find what you need more quickly.
We updated the Getting Started section to make it easier for you to evaluate Barcode Xpress.

Barcode Xpress for Node.js v13.4 introduces the following:

Added support in the License Manager for the following new command line operations:
- list operation to display installed licenses.
- remove operation to remove all installed licenses.
- getsdklist operation to fetch a list of installable toolkit licenses.
- installsdk operation to download and install a toolkit license.
Added interactive mode support for the License Manager’s command line operations. So, if the required parameters used in the command line mode for licensing the product are omitted, the user will be prompted to enter the missing information.

Addressed an issue where Barcode Xpress wasn't able to recognize squashed QR barcodes, where the horizontal and vertical module size was different.
Addressed an issue with algorithm improvement for Data Matrix barcodes with a damaged finder pattern to perform incorrect calculations for rectangular barcodes.
Fixed a bug in error correction algorithms which would occasionally prevent QR codes with damaged bars from being decoded.
Fixed a bug which could occasionally prevent PDF417 barcodes from being decoded properly when they were rotated 180 degrees.
Improved detection of QR Code version information when barcode is damaged.
Fixed a bug in the Java License Manager that would prevent a registration link from being created.
Fixed an out-of-bounds read operation for cropped images that could in some cases trigger illegal read exception while reading GS1 DataBar barcodes.

Barcode Xpress for Node.js v13.3 introduces the following improvements:

Added the ability to detect Code 39 and Code 39 Extended barcodes without start and stop patterns.
Improved barcode performance:
- Increased the algorithm speed by 5-20% for 1D barcodes (depending on input image).
- Increased the algorithm accuracy for Code 39, Code 39 Extended, and Patch Code barcode types.
Added support for Ubuntu 20.04 operating system.
Added support for Node.js v14 and dropped support for Node.js v8.

Barcode Xpress for Node.js v13.2 introduces the following improvements:

Support for Node.js 12.
Added support for UPU S18 4-State, MicroPDF417, and PLANET barcodes.
Accuracy and performance improvements for Code 128, Data Matrix, PDF417, QR Codes, Code 39, Code 93, and GS1 DataBar barcodes.
Added support for Royal Post 4-State variable length decoding.
Added BarcodeType object enumerating supported barcode types.
Several additional analyze result properties have been exposed.
Removed some third party Node.js package dependencies.
Now using Node.js Jimp to support major image formats.
API change to analyze function. See Upgradingfrom v11 to v13 for more information.
The analyze function now allows the input image parameter to be a Promise.
The License Manager and Server Licensing Utility are now supported on all Java Runtime Environments 1.8 or later.
Updated the Server Licensing Utility to support annual licensing.
Added a new licensing option - Metered Licensing.
Added support for CentOS 8 operating system (see notes).
Improved documentation.
