This article demonstrates how to duplicate a page within a PDF document using Spire.PDF for Java.
import com.spire.pdf.PdfDocument;
import com.spire.pdf.PdfPageBase;
import com.spire.pdf.graphics.PdfMargins;
import com.spire.pdf.graphics.PdfTemplate;
import java.awt.geom.Dimension2D;
import java.awt.geom.Point2D;
public class DuplicatePage {
public static void main(String[] args) {
//Load a sample PDF document
PdfDocument pdf = new PdfDocument("C:\\Users\\Administrator\\Desktop\\original.pdf");
//Get the first page
PdfPageBase page = pdf.getPages().get(0);
//Get the page size
Dimension2D size = page.getActualSize();
//Create a template based on the page
PdfTemplate template = page.createTemplate();
for (int i = 0; i < 10; i++) {
//Add a new page to the document
page = pdf.getPages().add(size, new PdfMargins(0));
//Draw template on the new page
page.getCanvas().drawTemplate(template, new Point2D.Float(0, 0));
}
//Save the file
pdf.saveToFile("output/DuplicatePage.pdf");
}
}
