Let's start with QR codes as this barcode is pretty common these days. IText 7 supports, as already mentioned, only two types of 2D barcodes: QR codes and Data Matrixes. Matrix or multi-dimensional (2D) barcodes are represented by black and white "dots." These barcodes are compact and capable of holding high-capacity symbols in the unit area. Additionally, my project has recently been upgraded to the latest libraries (Spring Boot 2.4.2 and iText 7.1.14). Please check my previous article where I covered that. Prerequisite: All the codes below, expect iText 7, are basic knowledge. Therefore, I'll begin with an explanation of generating the 2D barcodes, because there are only two of them. The section dedicated to 1D barcodes contains some generalization as there are five supported barcodes. Nevertheless, I believe the library supports all the common ones. IText 7 library supports many barcodes, but not all the options mentioned on Wikipedia. In general, we recognize two basic barcode types: If you want to see some examples of barcodes, please check the barcode sheet on their site. Most barcode standards are managed by the GS1 organization. Here is a simple definition of ‘barcode’ according to Wikipedia:Ī barcode or bar code is a method of representing data in a visual, machine-readable form. Firstly, I'll provide a short overview of barcodes, and then demonstrate barcode generation for every supported barcode type in the library. Here, I focus on the barcode support provided by the iText 7 library. default page ( home.In my previous article, I reviewed the basics of iText 7. Testing the ApplicationTo test this sample application, deploy the project on Tomcat server under a context named SpringMvcPdfViewDemo. Note that the ResourceBundleViewResolver has higher priority ( order=”1”) than the InternalResourceViewResolver ( order=”2”) so the view names specified in the views.properties are processed first.Finally we would have the following project structure in Eclipse IDE: 8.
