[Example 1] Cross-document copying

import com.spire.pdf.*;
import com.spire.pdf.graphics.PdfMargins;
import com.spire.pdf.graphics.PdfTemplate;

import java.awt.*;
import java.awt.geom.Dimension2D;

public class Copy1 {
    public static void main(String[]args){
        //加载两个PDF文档
        PdfDocument pdf1 = new PdfDocument("test1.pdf");
        PdfDocument pdf2 = new PdfDocument("test2.pdf");

        //获取pdf1的第一页，并根据页面创建模板
        PdfPageBase page = pdf1.getPages().get(0);
        Dimension2D size = page.getSize();
        PdfTemplate template = page.createTemplate();

        //在pdf2中第一页插入从复制的pdf1中绘制的模板
        pdf2.getPages().insert(0,size,new PdfMargins(0,0));
        pdf2.getPages().get(0).getCanvas().drawTemplate(template,new Point(0,0));

        //保存pdf2
        pdf2.saveToFile("result.pdf",FileFormat.PDF);
        pdf2.dispose();
    }

[Example 2] copy in the same document

import com.spire.pdf.*;
import com.spire.pdf.graphics.PdfMargins;
import com.spire.pdf.graphics.PdfTemplate;

import java.awt.*;
import java.awt.geom.Dimension2D;

public class Copy2 {
    public static void main(String[]args){
        //加载测试文档
        PdfDocument pdf = new PdfDocument("test1.pdf");

        //获取第一页，并将于页面创建模板
        PdfPageBase page = pdf.getPages().get(0);
        Dimension2D size = page.getSize();
        PdfTemplate template = page.createTemplate();

        //在文档末循环添加两张绘制好的页面模板
        for(int i=0; i<2; i++){
            page = pdf.getPages().add(size, new PdfMargins(0));
            page.getCanvas().drawTemplate(template, new Point(0, 0));
        }

        //在第一页插入一张绘制好的页面模板
        pdf.getPages().insert(0,size,new PdfMargins(0,0));
        pdf.getPages().get(0).getCanvas().drawTemplate(template,new Point(0,0));

        //保存文档
        pdf.saveToFile("result1.pdf",FileFormat.PDF);
    }
