Convert Specific Page to PNG Image in OneNote - Java

Introduction

In this tutorial, you’ll learn how to use Aspose.Note for Java to convert a specific page from a OneNote document into a PNG image. We’ll break down the process into easy-to-follow steps to help you seamlessly integrate this functionality into your Java application.

Prerequisites

Before getting started, ensure you have the following:

1. Java Development Kit (JDK): Make sure you have JDK installed on your system.
2. Aspose.Note for Java Library: Download and install the Aspose.Note for Java library from the website.
3. OneNote Document: Have a OneNote document ready from which you want to convert a specific page to PNG.

Import Packages

First, you need to import the necessary packages to your Java file:

import java.io.IOException;
import com.aspose.note.Document;
import com.aspose.note.ImageSaveOptions;
import com.aspose.note.LoadOptions;
import com.aspose.note.SaveFormat;

Step 1: Load the OneNote Document

// Load the document into Aspose.Note.
String dataDir = "Your Document Directory";
Document oneFile = new Document(dataDir + "Sample1.one", new LoadOptions());

In this step, we load the OneNote document using Aspose.Note’s Document class.

Step 2: Initialize ImageSaveOptions Object

// Initialize ImageSaveOptions object
ImageSaveOptions opts = new ImageSaveOptions(SaveFormat.Png);

Here, we initialize an ImageSaveOptions object and specify the save format as PNG.

Step 3: Set Page Index

// set page index
opts.setPageIndex(0);

Set the index of the page you want to convert. Note that page indexing starts from 0.

Step 4: Save the Document as PNG

// Save the document as PNG.
oneFile.save(dataDir + "ConvertSpecificPageToPngImage_out.png", opts);

Finally, save the document with the specified page converted to a PNG image.

Congratulations! You’ve successfully learned how to convert a specific page from a OneNote document to a PNG image using Aspose.Note for Java.
