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();
