package com.nattatat.jrPrintToPdf.Service;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.stereotype.Service;

import net.sf.jasperreports.engine.JRException;

import java.io.*;

@Service
public class JasperReportService{

    protected final static Logger log = LogManager.getLogger(JasperReportService.class);

    public void convertJrprintToPdf(String jrPrintFilePath, String pdfOutputPath) {
        log.info("\noutput: " + pdfOutputPath);
        try {
            JasperPrint jasperPrint = (JasperPrint) JRLoader.loadObjectFromFile(jrPrintFilePath);

            ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

            // Set the export font map for PDF
            JRPdfExporter exporter = new JRPdfExporter();
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
            exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream);
            exporter.setParameter(JRPdfExporterParameter.CHARACTER_ENCODING, "UTF-8");
                        
            exporter.exportReport();

            JasperExportManager.exportReportToPdfFile(jasperPrint, pdfOutputPath);

            byte[] byteArray = outputStream.toByteArray();

            // Save the byte array to a file (optional)
            try (FileOutputStream fileOutputStream = new FileOutputStream(pdfOutputPath)) {
                fileOutputStream.write(byteArray);
                System.out.println("PDF file saved successfully.");
            } catch (IOException e) {
                e.printStackTrace();
            }

            System.out.println("PDF exported successfully.");
        } catch (JRException e) {
            e.printStackTrace();
            System.out.println("Error exporting to PDF.");
        }
    }

    public void convertJrprintToPdfa(String jrPrintFilePath, String pdfOutputPath) throws FileNotFoundException {
        try {
            // Load .jrprint file
            JasperPrint jasperPrint = (JasperPrint) JRLoader.loadObject(new File(jrPrintFilePath));
            FileOutputStream fileOutputStream = new FileOutputStream(pdfOutputPath);

            // Create PdfAWriter
            PdfWriter pdfWriter = new PdfWriter(fileOutputStream);
            PdfADocument pdfADocument = new PdfADocument(pdfWriter, PdfAConformanceLevel.PDF_A_1B,
                    new PdfOutputIntent("Custom", "", "http://www.color.org", "sRGB IEC61966-2.1", null));

            // Create JasperReports exporter
            JRPdfExporter exporter = new JRPdfExporter();

            // Configure exporter
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
            exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, fileOutputStream);
            exporter.setParameter(JRPdfExporterParameter.CHARACTER_ENCODING, "UTF-8");

            // Export the report to PDF/A
            exporter.exportReport();

            // Close the PdfADocument
            pdfADocument.close();

            System.out.println("PDF exported successfully.");
        } catch (JRException | IOException e) {
            e.printStackTrace();
        }
    }
}

And this is my fonts.xml for embedded font
 

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>

    <!-- The jrprint file use this font families. -->
    <fontFamily name="TH Sarabun New">
        <normal><![CDATA[fonts/TH Sarabun New/THSarabunNew.ttf]]></normal>
        <bold><![CDATA[fonts/TH Sarabun New/THSarabunNewBold.ttf]]></bold>
        <italic><![CDATA[fonts/TH Sarabun New/THSarabunNewItalic.ttf]]></italic>

        <pdfEmbedded><![CDATA[true]]></pdfEmbedded>

        <pdfEmbedded><![CDATA[true]]></pdfEmbedded>
    </fontFamily>

    <fontFamily name="Angsana New">
        <normal><![CDATA[fonts/Angsana New/ANGSA.ttf]]></normal>
        <bold><![CDATA[fonts/Angsana New/angsab.ttf]]></bold>

        <boldItalic><![CDATA[fonts/Angsana New/AngsanaNewBoldItalic.ttf]]></boldItalic>
        <pdfEmbedded><![CDATA[true]]></pdfEmbedded>
    </fontFamily>

</fontFamilies>

From these code I used. The .pdf result didn't show Thai text (Show only English text).

Hi,

Have you tried to specify <pdfEncoding>Identity-H</pdfEncoding> for your font families?

I hope this helps.

Dear Teodor danciu

I tried to add <pdfEncoding> tag but not sure it correct?, Or I need to edit somethings else. Here is it.
 

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>

    <!-- The jrprint file use this font families. -->
    <fontFamily name="TH Sarabun New">
        <normal><![CDATA[fonts/TH Sarabun New/THSarabunNew.ttf]]></normal>
        <bold><![CDATA[fonts/TH Sarabun New/THSarabunNewBold.ttf]]></bold>
        <italic><![CDATA[fonts/TH Sarabun New/THSarabunNewItalic.ttf]]></italic>
        <boldItalic><![CDATA[fonts/TH Sarabun New/THSarabunNewBoldItalic.ttf]]></boldItalic>
        <pdfEmbedded><![CDATA[true]]></pdfEmbedded>
        <pdfEncoding>ISO-8859-1</pdfEncoding>
    </fontFamily>

</fontFamilies>

I did not suggest to use ISO-8859-1, which is Latin1. I suggested to use Identity-H.

I hope this helps.
