Save to Grayscale Image in OneNote - Aspose.Note

Introduction

In this tutorial, we’ll explore how to save a document as a grayscale image in OneNote using Aspose.Note for Java. Grayscale images are monochromatic images where the color information is represented only by shades of gray. Aspose.Note is a powerful Java API that allows manipulation of Microsoft OneNote documents programmatically.

Prerequisites

Before we begin, ensure you have the following:

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

Import Packages

To get started, import the necessary packages:

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

Step 1: Load the Document

First, load the document into Aspose.Note. Replace "Your Document Directory" with the path to your document directory and "Aspose.one" with the name of your OneNote document.

String dataDir = "Your Document Directory";
Document oneFile = new Document(dataDir + "Aspose.one");

Step 2: Set Output Path and Options

Define the output path for the grayscale image and specify the saving options. We’ll set the color mode to grayscale.

dataDir = dataDir + "SaveAsGrayscaleImage_out.png";
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.Png);
options.setColorMode(ColorMode.GrayScale);

Step 3: Save the Document

Finally, save the document as a grayscale image using the specified options.

oneFile.save(dataDir, options);
