I'm working with the harupdf library to create .pdf files. I encounter the following problem. I can not set a source barcode and it does not show me the bars and if the numbers that make up the code. Google searching I realize that is not possible , the solution is to create an image and embed it in the file. Well that need . Generate barcode image and save it to a file and then embed it in .pdf . Any idea where to start ??? Of course, many thanks.
