Convert to Markdown in Java Slides

Introduction Convert to Markdown in Java Slides

In this step-by-step guide, you will learn how to convert a PowerPoint presentation to Markdown format using Aspose.Slides for Java. Aspose.Slides is a powerful API that allows you to work with PowerPoint presentations programmatically. We will walk through the process and provide the Java source code for each step.

Prerequisites

Before you begin, make sure you have the following prerequisites:

• Aspose.Slides for Java: You need to have Aspose.Slides for Java API installed. You can download it from here.
• Java Development Environment: You should have a Java development environment set up on your machine.

Step 1: Import Aspose.Slides Library

First, you need to import the Aspose.Slides library into your Java project. You can do this by adding the following Maven dependency to your project’s pom.xml file:

<dependency>
    <groupId>com.aspose</groupId>
    <artifactId>aspose-slides</artifactId>
    <version>YOUR_VERSION_HERE</version>
</dependency>

Replace YOUR_VERSION_HERE with the appropriate version of Aspose.Slides for Java.

Step 2: Load the PowerPoint Presentation

Next, you’ll load the PowerPoint presentation that you want to convert to Markdown. In this example, we assume that you have a presentation file named “PresentationDemo.pptx.”

// Path to source presentation
String presentationName = "PresentationDemo.pptx";
Presentation pres = new Presentation(presentationName);

Make sure to provide the correct path to your presentation file.

Step 3: Set Markdown Conversion Options

Now, let’s set the options for Markdown conversion. We will specify that we want to export visual content and set a folder for saving images.

// Path and folder name for saving markdown data
String outPath = "output-folder/";

// Create Markdown creation options
MarkdownSaveOptions mdOptions = new MarkdownSaveOptions();

// Set parameter for render all items (items that are grouped will be rendered together).
mdOptions.setExportType(MarkdownExportType.Visual);

// Set folder name for saving images
mdOptions.setImagesSaveFolderName("md-images");

// Set path for folder images
mdOptions.setBasePath(outPath);

You can adjust these options according to your requirements.

Step 4: Convert Presentation to Markdown

Now, let’s convert the loaded presentation to Markdown format and save it.

// Save presentation in Markdown format
pres.save(outPath + "pres.md", SaveFormat.Md, mdOptions);

Replace "pres.md" with the desired name for your Markdown file.

Step 5: Cleanup

Finally, don’t forget to dispose of the presentation object when you’re done.

if (pres != null) pres.dispose();
