Create OneNote Document and Save to HTML - Java

Introduction

Aspose.Note for Java is a powerful library that allows developers to work with Microsoft OneNote files programmatically. In this tutorial, we will explore how to create a OneNote document and save it to HTML format using Aspose.Note for Java.

Prerequisites

Before we begin, ensure that you have the following:

Java Development Kit (JDK) installed on your system.
Aspose.Note for Java library. You can download it from here .
Basic knowledge of Java programming.

Import Packages

First, import the necessary packages to your Java project:

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.nio.file.Paths;
import com.aspose.note.CssSavingArgs;
import com.aspose.note.Document;
import com.aspose.note.FontFaceType;
import com.aspose.note.FontSavingArgs;
import com.aspose.note.HtmlSaveOptions;
import com.aspose.note.ICssSavingCallback;
import com.aspose.note.IFontSavingCallback;
import com.aspose.note.IImageSavingCallback;
import com.aspose.note.ImageSavingArgs;
import com.aspose.note.ResourceExportType;

Step 1: Create a OneNote Document Object

Document document = new Document("Path_to_your_sample_one_file");

This code initializes a Document object by loading a sample OneNote file.

Step 2: Save as HTML to Memory Stream

HtmlSaveOptions options = new HtmlSaveOptions();
options.setExportCss(ResourceExportType.ExportEmbedded);
options.setExportImages(ResourceExportType.ExportEmbedded);
options.setExportFonts(ResourceExportType.ExportEmbedded);
options.setFontFaceTypes(FontFaceType.Ttf);

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
document.save(outputStream, options);

Here, we set up the HTML save options and save the document to a memory stream.

Step 3: Save as HTML with Resources in Separate Files

HtmlSaveOptions options = new HtmlSaveOptions();
options.setExportCss(ResourceExportType.ExportEmbedded);
options.setExportFonts(ResourceExportType.ExportEmbedded);
options.setExportImages(ResourceExportType.ExportEmbedded);

document.save("output_directory/document.html", options);

This step saves the document as HTML with resources like CSS, fonts, and images in separate files.

Step 4: Save as HTML to Memory Stream with Callbacks to Save Resources

Document document = new Document("Path_to_your_sample_one_file");

UserSavingCallbacks savingCallbacks = new UserSavingCallbacks();
savingCallbacks.setRootFolder("documentFolder");
savingCallbacks.setCssFolder("css");
savingCallbacks.setKeepCssStreamOpened(true);
savingCallbacks.setImagesFolder("images");
savingCallbacks.setFontsFolder("fonts");

HtmlSaveOptions options = new HtmlSaveOptions();
options.setFontFaceTypes(FontFaceType.Ttf);
options.setCssSavingCallback(savingCallbacks);
options.setImageSavingCallback(savingCallbacks);
options.setFontSavingCallback(savingCallbacks);
options.setExportCss(ResourceExportType.ExportEmbedded);
options.setExportImages(ResourceExportType.ExportEmbedded);
options.setExportFonts(ResourceExportType.ExportEmbedded);

File dir = new File(savingCallbacks.getRootFolder());
if (!dir.exists()) {
    dir.mkdir();
}

document.save(Paths.get(savingCallbacks.getRootFolder(), "document.html").toString(), options);

Here, we save the document as HTML to a memory stream using callbacks to handle resource saving.
