Introduction

In this tutorial, you will learn how to import HTML text into a PowerPoint presentation using Java with the help of Aspose.Slides. This step-by-step guide will walk you through the process from importing necessary packages to saving your PowerPoint file.

Prerequisites

Before you begin, ensure you have the following prerequisites:

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

Import Packages

First, import the necessary packages from Aspose.Slides and standard Java libraries:

import com.aspose.slides.*;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

Step 1: Set Up Your Environment

Ensure you have a Java project set up with Aspose.Slides for Java included in your build path.

Step 2: Initialize Presentation Object

Create an empty PowerPoint presentation (Presentation object):

String dataDir = "Your Document Directory";
Presentation pres = new Presentation();

Step 3: Access Slide and Add AutoShape

Access the default first slide of the presentation and add an AutoShape to accommodate the HTML content:

ISlide slide = pres.getSlides().get_Item(0);
IAutoShape ashape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 10, (float) pres.getSlideSize().getSize().getWidth() - 20, (float) pres.getSlideSize().getSize().getHeight() - 10);
ashape.getFillFormat().setFillType(FillType.NoFill);

Step 4: Add Text Frame

Add a text frame to the shape:

ashape.addTextFrame("");

Step 5: Load HTML Content

Load the HTML file content using a stream reader and add it to the text frame:

String htmlContent = new String(Files.readAllBytes(Paths.get(dataDir + "file.html")));
ashape.getTextFrame().getParagraphs().addFromHtml(htmlContent);

Step 6: Save the Presentation

Save the modified presentation to a PPTX file:

pres.save(dataDir + "output_out.pptx", SaveFormat.Pptx);

Conclusion
