Barcode Xpress for Linux v13.5

Barcode Xpress for Linux v13.5 introduces the following:

• New Features & Improvements
• Product Updates & Fixes
• Documentation Updates

13.5 New Features and Improvements

• Evaluate Barcode Xpress - You can now run Barcode Xpress without an installed license, making it easier to evaluate the product. Barcode Xpress now automatically runs in Watermark evaluation mode if started without a license. For more information, refer to the Try It! section of the documentation.
• 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.

13.5 Product Updates and Fixes

• 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.

13.5 Documentation Updates

• 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 Linux v13.4

Barcode Xpress for Linux v13.4 introduces the following:

• New Features & Improvements
• Product Updates & Fixes

13.4 New Features and Improvements

• 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.

13.4 Product Updates and Fixes

• 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 Linux v13.3

Barcode Xpress for Linux 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.
