Get Portion Rectangle in PowerPoint with Java

Introduction

Creating dynamic presentations in Java is a breeze with Aspose.Slides for Java. In this tutorial, we’ll dive into the nitty-gritty of getting the portion rectangle in PowerPoint using Aspose.Slides. We’ll cover everything from setting up your environment to breaking down the code step-by-step. So, let’s get started!

Prerequisites

Before we jump into the code, let’s ensure you have everything you need to follow along smoothly:

1. Java Development Kit (JDK): Make sure you have JDK 8 or above installed on your machine.
2. Aspose.Slides for Java: Download the latest version from here.
3. Integrated Development Environment (IDE): Eclipse, IntelliJ IDEA, or any other Java IDE of your choice.
4. Basic Knowledge of Java: Understanding of Java programming is essential.

Import Packages

First things first, let’s import the necessary packages. This will include Aspose.Slides and a few others for handling our task efficiently.

import com.aspose.slides.*;
import com.aspose.slides.examples.RunExamples;
import java.awt.*;
import java.awt.geom.Rectangle2D;

Step 1: Setting Up the Presentation

The first step is to create a new presentation. This will be our canvas to work on.

Presentation pres = new Presentation();

Step 2: Creating a Table

Now, let’s add a table to the first slide of our presentation. This table will contain the cells where we’ll add our text.

ITable tbl = pres.getSlides().get_Item(0).getShapes().addTable(50, 50, new double[]{50, 70}, new double[]{50, 50, 50});

Step 3: Adding Paragraphs to Cells

Next, we’ll create paragraphs and add them to a specific cell in the table. This involves clearing any existing text and then adding new paragraphs.

// Create paragraphs
IParagraph paragraph0 = new Paragraph();
paragraph0.getPortions().add(new Portion("Text "));
paragraph0.getPortions().add(new Portion("in0"));
paragraph0.getPortions().add(new Portion(" Cell"));
IParagraph paragraph1 = new Paragraph();
paragraph1.setText("On0");
IParagraph paragraph2 = new Paragraph();
paragraph2.getPortions().add(new Portion("Hi there "));
paragraph2.getPortions().add(new Portion("col0"));
// Add text into the table cell
ICell cell = tbl.get_Item(1, 1);
cell.getTextFrame().getParagraphs().clear();
cell.getTextFrame().getParagraphs().add(paragraph0);
cell.getTextFrame().getParagraphs().add(paragraph1);
cell.getTextFrame().getParagraphs().add(paragraph2);

Step 4: Adding a Text Frame to an AutoShape

To make our presentation more dynamic, we’ll add a text frame to an AutoShape and set its alignment.

IAutoShape autoShape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 400, 100, 60, 120);
autoShape.getTextFrame().setText("Text in shape");
autoShape.getTextFrame().getParagraphs().get_Item(0).getParagraphFormat().setAlignment(TextAlignment.Left);

Step 5: Calculating Coordinates

We need to get the coordinates of the top-left corner of the table cell. This will help us place the shapes accurately.

double x = tbl.getX() + cell.getOffsetX();
double y = tbl.getY() + cell.getOffsetY();

Step 6: Adding Frames to Paragraphs and Portions

Using the IParagraph.getRect() and IPortion.getRect() methods, we can add frames to our paragraphs and portions. This involves iterating through the paragraphs and portions, creating shapes around them, and customizing their appearance.

for (IParagraph para : cell.getTextFrame().getParagraphs()) {
    if ("".equals(para.getText())) continue;
    Rectangle2D.Float rect = (Rectangle2D.Float) para.getRect().clone();
    IAutoShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(
        ShapeType.Rectangle,
        (float) rect.getX() + (float) x,
        (float) rect.getY() + (float) y,
        (float) rect.getWidth(),
        (float) rect.getHeight()
    );
    shape.getFillFormat().setFillType(FillType.NoFill);
    shape.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.YELLOW);
    shape.getLineFormat().getFillFormat().setFillType(FillType.Solid);
    for (IPortion portion : para.getPortions()) {
        if (portion.getText().contains("0")) {
            rect = portion.getRect();
            shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(
                ShapeType.Rectangle,
                (float) rect.getX() + (float) x,
                (float) rect.getY() + (float) y,
                (float) rect.getWidth(),
                (float) rect.getHeight()
            );
            shape.getFillFormat().setFillType(FillType.NoFill);
        }
    }
}

Step 7: Adding Frames to AutoShape Paragraphs

Similarly, we’ll add frames to the paragraphs in our AutoShape, enhancing the presentation’s visual appeal.

for (IParagraph para : autoShape.getTextFrame().getParagraphs()) {
    Rectangle2D.Float rect = (Rectangle2D.Float) para.getRect().clone();
    IAutoShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(
        ShapeType.Rectangle,
        (float) rect.getX() + autoShape.getX(),
        (float) rect.getY() + autoShape.getY(),
        (float) rect.getWidth(),
        (float) rect.getHeight()
    );
    shape.getFillFormat().setFillType(FillType.NoFill);
    shape.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.YELLOW);
    shape.getLineFormat().getFillFormat().setFillType(FillType.Solid);
}

Step 8: Saving the Presentation

Finally, we’ll save our presentation to a specified path.

String outPath = "path_to_output_directory";
pres.save(outPath + "GetRect_Out.pptx", SaveFormat.Pptx);

Step 9: Cleaning Up

It’s good practice to dispose of the presentation object to free up resources.

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