How to Create the Payment Part

This example shows how to create the payment part, which contains the Swiss QR Code as well as the same information as text output. The payment part is created as a DIN A6 document, which can be placed on a A5 or A4 Document positioned in the bottom right corner.

import ch.codeblock.qrinvoice.FontFamily;
import ch.codeblock.qrinvoice.OutputFormat;
import ch.codeblock.qrinvoice.PageSize;
import ch.codeblock.qrinvoice.QrInvoicePaymentPartCreator;
import ch.codeblock.qrinvoice.model.QrInvoice;
import ch.codeblock.qrinvoice.model.builder.QrInvoiceBuilder;

import java.time.LocalDate;
import java.time.Month;
import java.util.Locale;

// ..

final QrInvoice qrInvoice = // create using QrInvoiceBuilder;

final PaymentPart paymentPart = QrInvoicePaymentPartCreator
    .create()
    .qrInvoice(qrInvoice)
    .outputFormat(OutputFormat.PDF)
    .pageSize(PageSize.A4)
    .fontFamily(FontFamily.HELVETICA)
    .locale(Locale.GERMAN)
    .createPaymentPart();

// the resulting byte array contains the Swiss QR Code as PDF
final byte[] paymentPartPdf = paymentPart.getData();

// meta data for the chosen OutputFormat for convenience
final String mimeType = paymentPart.getOutputFormat().getMimeType();
final String fileExtension = paymentPart.getOutputFormat().getFileExtension();

This will generate a PDF containing a payment part in the bottom right corner.
