Question

The following code is simplified case for my Java2D application which prints to PDF. It some how does not print ‘Dotted I in turkish language.‘ using the PDFGrahics2D.

import com.lowagie.text.pdf.PdfWriter;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfTemplate;
import com.lowagie.text.pdf.DefaultFontMapper;
import com.lowagie.text.pdf.BaseFont;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Rectangle;

import java.io.FileOutputStream;
import java.io.File;
import java.io.IOException;
import java.awt.Graphics2D;
import java.awt.Font;

public class DottedIExampleWithGraphics2D
{

    private static final float WIDTH = 900;
    private static final float HEIGHT = 500;
    private DefaultFontMapper mapper = new DefaultFontMapper();

    public void testWriteOfStringWithFont() throws IOException, DocumentException
    {

        File fontFile = new File("c:/windows/fonts/arialuni.ttf");
        BaseFont bf = BaseFont.createFont(fontFile.getAbsolutePath(),
                BaseFont.IDENTITY_H,
                BaseFont.NOT_EMBEDDED);
        Font theFont = mapper.pdfToAwt(bf, 18);
        Document document = new Document(new Rectangle(WIDTH, HEIGHT));

        File testFile = new File("learning_withfont.pdf");
        FileOutputStream fos = new FileOutputStream(testFile);
        PdfWriter writer = PdfWriter.getInstance(document, fos);
        document.open();

        PdfContentByte cb = writer.getDirectContent();
        PdfTemplate tp = cb.createTemplate(WIDTH, HEIGHT);
        cb.addTemplate(tp, 0, 0);
        Graphics2D graphics = tp.createGraphics(WIDTH, HEIGHT, mapper);

        graphics.setFont(theFont);
        graphics.drawString(" \u0130 , \u0131 ", 25, 50);

        graphics.drawString(bf.getPostscriptFontName(), 25, 100);

        //
        graphics.dispose();
        document.close();

        System.out.println("testFile.getAbsolutePath() = " + testFile.getAbsolutePath());
    }

    /**
     */
    public static void main(String[] args) throws IOException, DocumentException
    {
        new DottedIExampleWithGraphics2D().testWriteOfStringWithFont();
    }
}

The output is like this.

The problem is how to print such characters to PDFGraphics2D. The java code for creating PDF normally, works. Code is here for quick reference.

import com.lowagie.text.Chunk;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Font;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.BaseFont;
import com.lowagie.text.pdf.PdfWriter;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class DottedIExample
{

    /**
     * Creates a PDF document. write a string and font name
     */
    public void createPdf(String filename) throws IOException, DocumentException
    {

        Document document = new Document();
        PdfWriter.getInstance(document, new FileOutputStream(filename));

        document.open();
        File fontFile = new File("c:/windows/fonts/arialuni.ttf");
        BaseFont bf = BaseFont.createFont(fontFile.getAbsolutePath(),
                BaseFont.IDENTITY_H,
                BaseFont.NOT_EMBEDDED);
        Font font = new Font(bf, 12);
        document.add(new Paragraph(bf.getPostscriptFontName(), font));
        document.add(new Paragraph("\u0131 , \u0130", font));
        document.add(Chunk.NEWLINE);

        document.close();
    }

    /**
     */
    public static void main(String[] args) throws IOException, DocumentException
    {
        File result = new File("dottedi.pdf");
        new DottedIExample().createPdf(result.getAbsolutePath());
        System.out.println("result at = " + result.getAbsolutePath());
    }
}

Answer 1

The problem was with mapper. Its awtToPdf()/pdf2awt() should be setup to return the correct font.

Fixed code , just for reference.. (actual setup of mapper is more complicated)

import com.lowagie.text.pdf.PdfWriter;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfTemplate;
import com.lowagie.text.pdf.DefaultFontMapper;
import com.lowagie.text.pdf.BaseFont;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Rectangle;

import java.awt.*;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.File;
import java.io.IOException;

public class DottedIExampleWithGraphics2D {

    private static final File aFontFile = new File(("c:/windows/fonts/arialuni.ttf"));
    private static final float WIDTH = 90;
    private static final float HEIGHT = 50;
    private DefaultFontMapper mapper = new DefaultFontMapper() {
        @Override
        public BaseFont awtToPdf(Font font) {
            try {
                return BaseFont.createFont(aFontFile.getAbsolutePath(),
                        BaseFont.IDENTITY_H,
                        BaseFont.NOT_EMBEDDED);
            } catch (DocumentException e) {
                e.printStackTrace();  //blah
            } catch (IOException e) {
                e.printStackTrace();  //blah
            }
            return null;
        }

        @Override
        public Font pdfToAwt(BaseFont baseFont, int i) {
            try {
                return Font.createFont(Font.TRUETYPE_FONT, new FileInputStream(aFontFile));
            } catch (FontFormatException e) {
                e.printStackTrace();  //blah
            } catch (IOException e) {
                e.printStackTrace();  //blah
            }
            return null;
        }
    };


    public void testWriteOfStringWithFont() throws IOException, DocumentException {


        Font theFont = mapper.pdfToAwt(null, 18);
        Document document = new Document(new Rectangle(WIDTH, HEIGHT));

        File testFile = new File("learning_withfont.pdf");
        FileOutputStream fos = new FileOutputStream(testFile);
        PdfWriter writer = PdfWriter.getInstance(document, fos);
        document.open();

        PdfContentByte cb = writer.getDirectContent();
        PdfTemplate tp = cb.createTemplate(WIDTH, HEIGHT);
        cb.addTemplate(tp, 0, 0);
        Graphics2D graphics = tp.createGraphics(WIDTH, HEIGHT, mapper);

        graphics.setColor(Color.blue);
        graphics.setFont(theFont);
        graphics.drawString(" \u0130 , \u0131 , \u0049, \u0069", 10, 10);

        graphics.drawString("some", 10, 30);

        //
        graphics.dispose();
        document.close();

        System.out.println("testFile.getAbsolutePath() = " + testFile.getAbsolutePath());
    }

    /**
     */
    public static void main(String[] args) throws IOException, DocumentException {
        new DottedIExampleWithGraphics2D().testWriteOfStringWithFont();
    }
}
