Generate Multiple Barcodes on Single Image, Code16K Encoding & Decoding

What’s new in this release?

The new version of Aspose.BarCode for Java 6.0.0 has been released. There are many different types of barcodes, often referred to as barcode symbologies. From this release, the Aspose.BarCode API enables developers to decode the Code16K symbology. In the previous version, we added Code16K encoding; now both encoding and decoding Code16K are supported. Users can now retrieve all possible 1D barcodes using a single method call. The BarCodeReader.getAllPossibleBarCodes method allows them to do so. Please find the details of this feature in the documentation topic: Get all Possible 1D Barcodes from an Image. Barcode recognition percentage gives a clear picture based on the quality and performance parameters. The BarCodeReader.getRecognitionQuality method helps with that. We noticed time and memory consumption problems with the PatchCode symbology. When scanning PatchCodes from TIFF files memory consumption was around 150MB to 200MB. This has is now been fixed and memory usage is now around 40MB. Also, these sample graphics now take only 1.6 seconds to be recognized. The DataMatrix performance with large pictures has been upgraded. Previously, it took too long to be recognized. Key factors of this improvement are “Diagonal check” and “Strict angle check”. It’s now easy to generate multiple barcodes on a single image. We just need to follow a simple code snippet. The BarCodeBuilder.setThrowExceptionWhenCodeTextIncorrect method has been added for 1D barcodes. If the code text is incorrect and the value is set to true, an exception is thrown; else, the code text is corrected to match the barcode’s specification. An exception is always thrown for Databar symbologies if the code text is incorrect. It is never thrown for AustraliaPost, SingapurePost, Code39Extended, Code93Extended, Code16K, and Code128 symbologies if codetext is incorrect. Please see the following topic for help: 1D Barcodes with Optional Exception Message in Case of Wrong Code Text.  Below is the list of main improved features and bug fixes added in this release.

Overview: Aspose.BarCode for Java
Aspose.BarCode is a Java based visual component for generation & recognition of 1D & 2D barcodes to support Java, web applications and J2ME platform. It supports 29+ barcode symbologies like MSI, QR, OneCode, Australia Post, Aztec, Code128, Code11, EAN128, Codabar, Postnet, USPS and also supports image output in GIF, PNG, BMP & JPG formats. Other features include barcode size & color settings, rotation angle & caption. You can render barcodes to images, printers, HTTP servlet response & graphical objects too.
