EPUB is a standard file format for publishing eBooks or other electronic documents. The content in an EPUB file is reflowable, which means that the content automatically adjusts itself to fit the screen it is being displayed on. People who want to publish their eBooks may need to convert their works stored in Word documents to EPUB files. In this article, you will learn how to programmatically achieve this task using Spire.Doc for .NET.
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for .NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Doc
Convert Word to EPUB
The detailed steps are as follows:
- Create a Document instance.
- Load a sample Word document using Document.LoadFromFile() method.
- Save the document to EPUB using Document.SaveToFile() method.
- C#
- VB.NET
using Spire.Doc;
namespace WordtoEPUB
{
class Epub
{
static void Main(string[] args)
{
//Create a Document instance
Document document = new Document();
//Load a sample Word document
document.LoadFromFile("demo.docx");
//Convert the Word document to EPUB
document.SaveToFile("ToEpub.epub", FileFormat.EPub);
}
}
}
Convert Word to EPUB with a Cover Image
The detailed steps are as follows.
- Create a Document instance.
- Load a sample Word document using Document.LoadFromFile() method.
- Create a DocPicture instance, and then load an image using DocPicture.LoadImage() method.
- Save the Word document to EPUB with cover image using Document.SaveToEpub(String, DocPicture) method.
- C#
- VB.NET
using Spire.Doc;
using Spire.Doc.Fields;
using System.Drawing;
namespace ConvertWordToEpubWithCoverImage
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document doc = new Document();
//Load a sample Word document
doc.LoadFromFile("demo.docx");
//Create a DocPicture instance
DocPicture picture = new DocPicture(doc);
//Load an image
picture.LoadImage(Image.FromFile("CoverImage.png"));
//Save the Word document to EPUB with cover image
doc.SaveToEpub("ToEpubWithCoverImage.epub", picture);
}
}
