Introduction

In this tutorial, you will learn how to vertically align text within table cells in a PowerPoint presentation using Aspose.Slides for Java. Vertically aligning text is a crucial aspect of slide design, ensuring that your content is presented neatly and professionally. Aspose.Slides provides powerful features to manipulate and format presentations programmatically, giving you full control over every aspect of your slides.

Prerequisites

Before diving into this tutorial, ensure you have the following prerequisites:

  • Basic knowledge of Java programming.
  • JDK (Java Development Kit) installed on your machine.
  • Aspose.Slides for Java library. You can download it from here.
  • IDE (Integrated Development Environment) such as IntelliJ IDEA or Eclipse installed.

Import Packages

Before proceeding with the tutorial, make sure to import necessary Aspose.Slides packages into your Java file:

import com.aspose.slides.*;
import java.awt.*;

Step 1: Set up your Java project

Ensure you have set up a new Java project in your preferred IDE and added the Aspose.Slides library to your project’s build path.

Step 2: Initialize the Presentation object

Create an instance of the Presentation class to start working with a new PowerPoint presentation:

Presentation presentation = new Presentation();

Step 3: Access the first slide

Get the first slide from the presentation to add content to it:

ISlide slide = presentation.getSlides().get_Item(0);

Step 4: Define table dimensions and add a table

Define the column widths and row heights for your table, then add the table shape to the slide:

double[] dblCols = {120, 120, 120, 120};
double[] dblRows = {100, 100, 100, 100};
ITable tbl = slide.getShapes().addTable(100, 50, dblCols, dblRows);

Step 5: Set text content in table cells

Set text content for specific rows in the table:

tbl.getRows().get_Item(1).get_Item(0).getTextFrame().setText("10");
tbl.getRows().get_Item(2).get_Item(0).getTextFrame().setText("20");
tbl.getRows().get_Item(3).get_Item(0).getTextFrame().setText("30");

Step 6: Access the text frame and format text

Access the text frame and format the text within a specific cell:

ITextFrame txtFrame = tbl.get_Item(0, 0).getTextFrame();
IParagraph paragraph = txtFrame.getParagraphs().get_Item(0);
IPortion portion = paragraph.getPortions().get_Item(0);
portion.setText("Text here");
portion.getPortionFormat().getFillFormat().setFillType(FillType.Solid);
portion.getPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK);

Step 7: Align text vertically

Set the vertical alignment for text within the cell:

ICell cell = tbl.get_Item(0, 0);
cell.setTextAnchorType(TextAnchorType.Center);
cell.setTextVerticalType(TextVerticalType.Vertical270);

Step 8: Save the presentation

Save the modified presentation to a specified location on your disk:

String dataDir = "Your Document Directory";
presentation.save(dataDir + "Vertical_Align_Text_out.pptx", SaveFormat.Pptx);

Step 9: Cleanup resources

Dispose of the Presentation object to release resources:

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

Conclusion

By following these steps, you can effectively vertically align text within table cells in your Java PowerPoint presentations using Aspose.Slides. This capability enhances the visual appeal and clarity of your slides, ensuring your content is presented professionally.
