epublib

Epublib is a java library for reading/writing/manipulating epub files.

It consists of 2 parts: a core that reads/writes epub and a collection of tools. The tools contain an epub cleanup tool, a tool to create epubs from html files, a tool to create an epub from an uncompress html file. It also contains a swing-based epub viewer.

The core runs both on android and a standard java environment. The tools run only on a standard java environment.

This means that reading/writing epub files works on Android.

package nl.siegmann.epublib.examples;

import java.io.InputStream;
import java.io.FileOutputStream;
 
import nl.siegmann.epublib.domain.Author;
import nl.siegmann.epublib.domain.Book;

import nl.siegmann.epublib.epub.EpubWriter;
 
public class Translator {
  private static InputStream getResource( String path ) {
    return Translator.class.getResourceAsStream( path );
  }

  private static Resource getResource( String path, String href ) {
    return new Resource( getResource( path ), href );
  }

  public static void main(String[] args) {
    try {
      // Create new Book
      Book book = new Book();
      Metadata metadata = book.getMetadata();
       
      // Set the title
      metadata.addTitle("Epublib test book 1");
       
      // Add an Author
      metadata.addAuthor(new Author("Joe", "Tester"));
       
      // Set cover image
      book.setCoverImage(
        getResource("/book1/test_cover.png", "cover.png") );
       
      // Add Chapter 1
      book.addSection("Introduction",
        getResource("/book1/chapter1.html", "chapter1.html") );
       
      // Add css file
      book.getResources().add(
        getResource("/book1/book1.css", "book1.css") );
       
      // Add Chapter 2

        getResource("/book1/chapter2.html", "chapter2.html") );
       
      // Add image used by Chapter 2
      book.getResources().add(
        getResource("/book1/flowers_320x240.jpg", "flowers.jpg"));
       
      // Add Chapter2, Section 1
      book.addSection(chapter2, "Chapter 2, section 1",
        getResource("/book1/chapter2_1.html", "chapter2_1.html"));
       
      // Add Chapter 3
      book.addSection("Conclusion",
        getResource("/book1/chapter3.html", "chapter3.html"));
       
      // Create EpubWriter
      EpubWriter epubWriter = new EpubWriter();
       
      // Write the Book as Epub
      epubWriter.write(book, new FileOutputStream("test1_book1.epub"));
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}
