Split a PDF Page into multiple Pages
Spire.PDF for Java offers PdfPageBase.createTemplate().draw() method to draw the content of a source page on a new PDF page. Splitting a page into multiple pages actually means that the content of the source page will be drew on multiple smaller pages. The following are the main steps to split the first page into two pages:
- Create an object of PdfDocument class and load a sample PDF document using PdfDocument.loadFromFile() method.
- Get the desired page of PDF using PdfDocument.getPages().get() method.
- Create a new PDF document and set the page margins to 0.
- Set the page size of the new PDF to half or a fraction of that of the original.
- Add a new page to the new PDF document using PdfDocument.getPages().add() method.
- Draw content of source page on the new page using PdfPageBase.createTemplate().draw() method.
- Save the document to another file using PdfDocument.saveToFile() method.
- Java
import com.spire.pdf.*;
import com.spire.pdf.graphics.*;
import java.awt.geom.Point2D;
public class SplitPDF {
public static void main(String[] args) throws Exception {
//Create an object of PdfDocument class.
PdfDocument pdf = new PdfDocument();
//Load the sample PDF document
pdf.loadFromFile("Sample.pdf");
//Get the first page of PDF
PdfPageBase page = pdf.getPages().get(0);
//Create a new PDF document and remove page margins
PdfDocument newPdf = new PdfDocument();
newPdf.getPageSettings().getMargins().setAll(0);
//Horizontally Split
newPdf.getPageSettings().setWidth((float) page.getSize().getWidth());
newPdf.getPageSettings().setHeight((float) page.getSize().getHeight()/2);
////Vertically Split
//newPdf.getPageSettings().setWidth((float) page.getSize().getWidth()/2);
//newPdf.getPageSettings().setHeight((float) page.getSize().getHeight());
// Add a new page to the new PDF document
PdfPageBase newPage = newPdf.getPages().add();
//Set the PdfLayoutType to Paginate to make the content paginated automatically
PdfTextLayout layout = new PdfTextLayout();
layout.setBreak(PdfLayoutBreakType.Fit_Page);
layout.setLayout(PdfLayoutType.Paginate);
//Draw the content of source page in the new page
page.createTemplate().draw(newPage, new Point2D.Float(0, 0), layout);
//Save the Pdf document
newPdf.saveToFile("SplitPDF.pdf");
newPdf.close();
}

Hyperlinks in PowerPoint are clickable objects that enable you to jump to another slide in the same/different PowerPoint document or to a specific website. They are a great way to add additional resources to your slides, and they can also make the document more interactive. In addition to adding hyperlinks to PowerPoint documents, Spire.Presentation for Java also supports modifying and removing the existing hyperlinks. This article is going to introduce how to achieve the above two functions.
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.

Modify Hyperlinks in PowerPoint
With Spire.Presentation for Java, you are allowed to set a new hyperlink address and display text for the existing hyperlink. The following are the detailed steps to modify a hyperlink in PowerPoint.
- Create a Presentation object and load a PowerPoint document using Presentation.loadFromFile() method.
- Get a specified slide using Presentation.getSlides().get() method.
- Get the shapes of the specified slide using getShapes() method under ISlide interface, and then get the specified shape that contains the hyperlink using ShapeList.get() method.
- Get the text range of the existing hyperlink using IAutoShape.getTextFrame().getTextRange() method, and then set a new hyperlink display text for the text range using PortionEx.setText() method.
- Get the existing clickable hyperlink of the text range using TextCharacterProperties.getClickAction() method, and then set a new hyperlink address using ClickHyperlink.setAddress() method.
- Save the document to file using Presentation.saveToFile() method.
- Java
import com.spire.presentation.*;
public class modifyHyperlink {
public static void main(String[] args) throws Exception {
//Create a Presentation object and load a PowerPoint document
Presentation presentation = new Presentation();
presentation.loadFromFile("test.pptx");
//Get the shape that contains the hyperlink
IAutoShape shape = (IAutoShape)presentation.getSlides().get(0).getShapes().get(0);
//Edit the hyperlink text and address
shape.getTextFrame().getTextRange().setText("Spire.Presentation for Java");
shape.getTextFrame().getTextRange().getClickAction().setAddress("https://www.e-iceblue.com/Introduce/presentation-for-java.html");
//Save to file.
presentation.saveToFile("ModifyHyperlink.pptx", FileFormat.PPTX_2013);
}
}
Remove Hyperlinks in PowerPoint
When a hyperlink needs to be removed for some reason, Spire.Persentation for Java provides the TextCharacterProperties.setClickAction() method. And by setting its value to null, you could remove the hyperlink easily in PowerPoint. The detailed steps are as follows:
- Create a Presentation object and load a PowerPoint document using Presentation.loadFromFile() method.
- Get a specified slides using Presentation.getSlides().get() method.
- Get the shapes of the specified slide using getShapes() method under ISlide interface, and then get the specified shape that contains the hyperlink using ShapeList.get() method.
- Get the text range of the existing hyperlink using IAutoShape.getTextFrame().getTextRange() method, and then remove the hyperlink by setting the value of the TextCharacterProperties.setClickAction() method to null.
- Save the document to file using Presentation.saveToFile() method.
- Java
import com.spire.presentation.*;
public class removeHyperlink {
public static void main(String[] args) throws Exception {
//Create a Presentation object and load a PowerPoint document
Presentation presentation = new Presentation();
presentation.loadFromFile("test.pptx");
//Get the shape that contains the hyperlink.
IAutoShape shape = (IAutoShape)presentation.getSlides().get(0).getShapes().get(0);
//Set the click action to null to remove the hyperlink.
shape.getTextFrame().getTextRange().setClickAction(null);
//Save to file.
presentation.saveToFile("RemoveHyperlink.pptx", FileFormat.PPTX_2013);
}

A scatter (XY) chart is a two-dimensional chart that shows the relationship between two sets of variables. Each scatter chart has two axes: a horizontal axis (x-axis) and a vertical axis (y-axis), and it accepts only one data series. In this article, you will learn how to add a scatter chart to a PowerPoint slide using Spire.Presentation for Java.

Create a Scatter Chart in PowerPoint
Spire.Presentation for Java provides the ShapeCollection.appendChart(ChartType type, Rectangle2D rectangle, boolean init) method to add charts of a certain type to a presentation slide. The ChartType enumeration pre-defines 73 chart types, including scatter chart, column chart, pie chart, etc. The following are the main steps to add a scatter chart in PowerPoint.
- Create a Presentation object.
- Append a scatter chart to the specific slide using ShapeCollection.appendChart() method.
- Set the chart data through ChartData.get().setValue() method.
- Set the chart title, axes titles, series labels, etc. using the methods under IChart interface.
- Set the grid line style and data point line style.
- Save the document to file using Presentation.saveToFile() method.
