How to load custom font in FontFactory.register in iText

Question

I need your help in adding a custom font "arial.ttf" which is stored under the resources folder in my project in the FontFactory.register method in iText.

The font path is as follows in the project from Windows Explorer:

public_html\resources\fonts\arial.ttf

The code for referring to the font is:

FontFactory.register("/resources/fonts/arial.ttf", "my_bold_font");
Font myBoldFont = FontFactory.getFont("my_bold_font");

However when I ran the Java method, it always gives me the error:

java.io.IOException: /resources/fonts/arial.ttf not found as file or resource.

I tried with different paths for example:

/public_html/resources/fonts/arial.ttf

../resources/fonts/arial.ttf

/fonts/arial.ttf

/arial.ttf

But the result is the same that the file can't be found. So how to refer to the file?

@Satya I will be deploying the project to WAR and will be deploying it in Linux server. However I want to test it in my local weblogic as well. — 99maas, Jul 31 '15 at 13:14
`getServletContext().getRealPath(File.separator)+File.separator+"resources"+File.separator+"fonts"+File.separator+"arial.ttf"` — SatyaTNV, Jul 31 '15 at 13:17
@Satya should I replace the full path "/resources/fonts/arial.ttf" with the above one? — 99maas, Jul 31 '15 at 13:20
@Satya I did the code : FontFactory.register(getServletContext().getRealPath(File.separator)+File.separator+"resources"+File‌.separator+"fonts"+File.separator+"arial.ttf", "my_bold_font"); and it gave an error that Not a valid expression statement — 99maas, Jul 31 '15 at 13:23
Oh! where you are writing this code means in normal java or in servlets — SatyaTNV, Jul 31 '15 at 13:23
FontFactory.register("resources"+File‌.separator+"fonts"+File.separator+"arial.ttf", "my_bold_font"); — SatyaTNV, Jul 31 '15 at 13:26
@Satya File.separator is not recognized and it is giving that it is not a valid expression — 99maas, Jul 31 '15 at 13:28
don't copy and paste. type it. sometimes special characters will be added. But both are correct. — SatyaTNV, Jul 31 '15 at 13:32

You can get the path of the 'font' which are present in the resources folder, using contextClassLoader and can be used in the FontFactory file path.

URL font_path = Thread.currentThread().getContextClassLoader().getResource("fontname");
FontFactory.register(font_path.toString(), "test_font");

I have tested this code and it works fine.

The code was done by:

 FontFactory.register(System.getProperty("file.separator")+"resources"+System.getProperty("file.separator")+"fonts"+System.getProperty("file.separator")+"arial.‌ttf", "my_bold_font");
 Font myBoldFont = FontFactory.getFont("my_bold_font");

I have tried this for adding all fonts that are stored in a folder "src/main/webapp/resources/fonts" to the XMLWorkerFontProvider.

It worked successfully.

XMLWorkerFontProvider fontImp = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);

URL font_path = Thread.currentThread().getContextClassLoader().getResource("resources/fonts");

File directory = new File(font_path.getPath());

//get all the files from a directory

File[] fList = directory.listFiles();

for (File file : fList){

    System.out.println("Font File Path******************************   " +file.getPath());
    fontImp.register(file.getPath());
} 
FontFactory.setFontImp(fontImp);

Document document = new Document();
Rectangle one = new Rectangle(width,height);
document.setPageSize(one);
document.setMargins(1, 1, 1, 1);
ByteArrayOutputStream bos1 = new ByteArrayOutputStream();
PdfWriter pdfWriter=PdfWriter.getInstance(document, new FileOutputStream(folderPath+"/"+fileName));
document.open();

InputStream is = new ByteArrayInputStream(html.getBytes());
//XMLWorkerHelper.getInstance().parseXHtml(pdfWriter,document, is);
XMLWorkerHelper.getInstance().parseXHtml(pdfWriter,document, is, null, null,fontImp);
document.close();

I am using Spring Boot 2.2 with iText 5 (openpdf) and this code is working well when I execute the Spring Boot app.

import com.lowagie.text.Font;
import com.lowagie.text.FontFactory;
import com.lowagie.text.pdf.BaseFont;
import java.awt.*;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;

public class CustomFont {

    public static Font myFont;

    /**
     * This method should be loaded when you start the app for the first time.
     * @param resourceLoader The resource you can get using Spring @Autowired annotation and passing it to here.
     */
    public static void registerFont(ResourceLoader resourceLoader) {

        try {

            // Note the "classpath: " syntax.
            // I am storing my font in: src/main/resources/fonts/my-custom-font.ttf
            Resource resource = resourceLoader.getResource("classpath:/fonts/my-custom-font.ttf");
            FontFactory.register(resource.getURL().getPath(), "aliasCustomFontName");

        } catch (Exception e) {
            // When executing the unit tests, the font is not found so I am catching and ignoring it.
            // The fonts are not important for the unit tests in my case.
            e.printStackTrace();
        }

        myFont = FontFactory.getFont("aliasCustomFontName", BaseFont.WINANSI, true, 1, Font.NORMAL, Color.WHITE);
    }

    /**
     * You can use the custom font in your code with: CustomFont.myFont
     */

}
