Since we're on a major migration process of this website, some component documents here are out of sync right now. In the meantime you may want to look at the early version of the new website

We would very much like to receive any feedback on the new site, please join the discussion on the Camel user mailing list.
Available as of Camel 2.14 The barcode data format is based on the zxing library. The goal of this component is to create a barcode image from a String (marshal) and a String from a barcode image (unmarshal). You're free to use all features that zxing offers. DependenciesTo use the barcode data format in your camel routes you need to add the a dependency on camel-barcode which implements this data format. If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions). <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-barcode</artifactId> <version>x.x.x</version> </dependency> Using the Java DSLFirst you have to initialize the barcode data fomat class. You can use the default constructor, or one of parameterized (see JavaDoc). The default values are:
// QR-Code default DataFormat code = new BarcodeDataFormat(); If you want to use zxing hints, you can use the 'addToHintMap' method of your BarcodeDataFormat instance: code.addToHintMap(DecodeHintType.TRY_HARDER, Boolean.true); For possible hints, please consult the xzing documentation. Marshallingfrom("direct://code") .marshal(code) .to("file://barcode_out"); You can call the route from a test class with: template.sendBody("direct://code", "This is a testmessage!"); You should find inside the 'barcode_out' folder this image: UnmarshallingThe unmarshaller is generic. For unmarshalling you can use any BarcodeDataFormat instance. If you've two instances, one for (generating) QR-Code and one for PDF417, it doesn't matter which one will be used. from("file://barcode_in?noop=true") .unmarshal(code) // for unmarshalling, the instance doesn't matter .to("mock:out"); If you'll paste the QR-Code image above into the 'barcode_in' folder, you should find '
