Smartart (2)
This article will introduce how to extract text from SmartArt in PowerPoint in Java applications.
Firstly view the sample document:
import com.spire.presentation.Presentation;
import com.spire.presentation.diagrams.ISmartArt;
import java.io.*;
public class extractTextFromSmartArt {
public static void main(String[] args) throws Exception {
Presentation presentation = new Presentation();
presentation.loadFromFile("Sample.pptx");
//Create a new TXT File
String result = "output/extractTextFromSmartArt.txt";
File file=new File(result);
if(file.exists()){
file.delete();
}
file.createNewFile();
FileWriter fw =new FileWriter(file,true);
BufferedWriter bw =new BufferedWriter(fw);
bw.write("Below is extracted text from SmartArt:" + "\r\n");
//Traverse through all the slides of the PPT file and find the SmartArt shapes.
for (int i = 0; i < presentation.getSlides().getCount(); i++)
{
for (int j = 0; j < presentation.getSlides().get(i).getShapes().getCount(); j++)
{
if (presentation.getSlides().get(i).getShapes().get(j) instanceof ISmartArt)
{
ISmartArt smartArt = (ISmartArt)presentation.getSlides().get(i).getShapes().get(j);
//Extract text from SmartArt and append to the StringBuilder object.
for (int k = 0; k < smartArt.getNodes().getCount(); k++)
{
bw.write(smartArt.getNodes().get(k).getTextFrame().getText() + "\r\n");
}
}
}
}
bw.flush();
bw.close();
fw.close();
}
}

A SmartArt graphic is a visual representation of information and ideas. It can turn ordinary text into the predefined graphic, which makes the text information easier to understand. In this article, you will learn how to create a SmartArt in PowerPoint and custom its layout programmatically using Spire.Presentation for Java.
Install Spire.Presentation for Java
First of all, you're required to add the Spire.Presentation.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Create a SmartArt in PowerPoint
The detailed steps are as follows.
- Create a Presentation object.
- Get a specified slide using Presentation.getSlides().get() method.
- Insert a SmartArt into the specified slide using ISlide.getShapes().appendSmartArt() method.
- Set the style and color of the SmartArt using ISmartArt.setStyle() method and ISmartArt.setColorStyle() method.
- Loop through the nodes in SmartArt and remove all default nodes using ISmartArt.getNodes().removeNode() method.
- Add a parent node to the SmartArt using ISmartArt.getNodes().addNode() method, and then add 4 child nodes using ISmartArtNode.getChildNodes().addNode() method.
- Add text to each node using ISmartArtNode.getTextFrame().setText() method.
- Get the text range of the above added text using ISmartArtNode.getTextFrame().getTextRange() method, and then set the text font size using PortionEx.setFontHeight() method.
- Save the document to file using Presentation.saveToFile() method.
- Java
import com.spire.presentation.FileFormat;
import com.spire.presentation.ISlide;
import com.spire.presentation.Presentation;
import com.spire.presentation.diagrams.*;
public class AddSmartArt {
public static void main(String[] args) throws Exception {
//Create a Presentation object.
Presentation presentation = new Presentation();
//Get the first slide
ISlide slide = presentation.getSlides().get(0);
//Insert a SmartArt (Organization Chart) into the slide
ISmartArt smartArt = slide.getShapes().appendSmartArt(60, 60, 500, 400, SmartArtLayoutType.ORGANIZATION_CHART);
//Set the style and color of SmartArt
smartArt.setStyle(SmartArtStyleType.MODERATE_EFFECT);
smartArt.setColorStyle(SmartArtColorType.COLORFUL_ACCENT_COLORS_4_TO_5);
//Remove all default nodes
for (Object a : smartArt.getNodes()) {
smartArt.getNodes().removeNode(0);
}
//Add a parent node
ISmartArtNode node1 = smartArt.getNodes().addNode();
//Add 4 child nodes
ISmartArtNode node1_1 = node1.getChildNodes().addNode();
ISmartArtNode node1_2 = node1.getChildNodes().addNode();
ISmartArtNode node1_3 = node1.getChildNodes().addNode();
ISmartArtNode node1_4 = node1.getChildNodes().addNode();
//Add text to each node and set its font size
node1.getTextFrame().setText("General Manager");
node1.getTextFrame().getTextRange().setFontHeight(14f);
node1_1.getTextFrame().setText("Marketing Manager");
node1_1.getTextFrame().getTextRange().setFontHeight(12f);
node1_2.getTextFrame().setText("Operation Manager");
node1_2.getTextFrame().getTextRange().setFontHeight(12f);
node1_3.getTextFrame().setText("Human Resource Manager");
node1_3.getTextFrame().getTextRange().setFontHeight(12f);
node1_4.getTextFrame().setText("Account Manager");
node1_4.getTextFrame().getTextRange().setFontHeight(12f);
//Save the document
presentation.saveToFile("SmartArt.pptx", FileFormat.PPTX_2010);
presentation.dispose();
}
