[JAVA] Create PDF with itext7 ~ Hello World ~

Create PDF with itext7

There is a library called itext7 that creates PDF, but there are few Japanese documents, so I will summarize it. I will do it with eclipse + gradle.

build.gradle settings


dependencies {
~ Abbreviation ~
    //Added itext7
    implementation 'com.github.itext.itext7:layout:7.1.4'
    //Added Japanese font for itext7
    implementation 'com.github.itext.itext7:font-asian:7.1.4'
    //Added slf4j
    implementation 'org.slf4j:slf4j-log4j12:1.7.21'
allprojects {
    repositories {
        maven { url 'https://jitpack.io' }

If you do not read "slf4j" as well, the following error will occur.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Run Hello World


import java.io.File;

import com.itextpdf.kernel.pdf.PdfDocument;
import com.itextpdf.kernel.pdf.PdfWriter;
import com.itextpdf.layout.Document;
import com.itextpdf.layout.element.Paragraph;

public class HelloWorld {
    public static void main(String[] args) throws Exception {
        //Initialize PDF writer
        PdfWriter writer = new PdfWriter(new File("HelloWorld.pdf"));

        //Initialize PDF document
        PdfDocument pdf = new PdfDocument(writer);
        // Initialize document
        Document document = new Document(pdf);
        //Add paragraph to the document
        document.add(new Paragraph("Hello World!"));
        //Close document

Next time: Let's speak Japanese

Now, if you replace the "Hello World!" Part of the tutorial with Japanese ... that? Is it pure white? Next time starts from that area!
