import java.awt.image.BufferedImage;
import java.io.File;

public class PPTtoPNG {
    public static void main(String[] args) throws Exception{
        //創建Presentation對象
        Presentation ppt = new Presentation();

        //加載示例文檔
        ppt.loadFromFile("sample.pptx");

        //遍歷幻燈片
        for (int i = 0; i < ppt.getSlides().getCount(); i++) {
            //將幻燈片保存為BufferedImage對象
            BufferedImage image = ppt.getSlides().get(i).saveAsImage();

            //將BufferedImage保存為PNG格式文件
            String fileName =  String.format("ToImage.png", i);
            ImageIO.write(image, "PNG",new File(fileName));
        }
        ppt.dispose();

    }
}

 

 

將整個工作簿轉為PDF

import com.spire.xls.*;

public class ExcelToPDF {
    public static void main(String[] args) {
        //加載Excel文檔
        Workbook wb = new Workbook();
        wb.loadFromFile("test.xlsx");

        //調用方法保存為PDF格式
        wb.saveToFile("ToPDF.pdf",FileFormat.PDF);
    }
}

 

轉換結果

將指定工作表轉為PDF

import com.spire.xls.*;

public class ExcelToPDF {
    public static void main(String[] args) {
        //加載Excel文檔
        Workbook wb = new Workbook();
        wb.loadFromFile("test.xlsx");

        //獲取第2個工作表
        Worksheet sheet = wb.getWorksheets().get(1);

        //調用方法保存為PDF格式
        sheet.saveToPdf("ToPDF2.pdf");
    }
}

 

轉換結果

Spire.XLS for Java支持將Excel文檔轉為多種文檔格式，包括PDF、圖片、html、XPS、XML、CSV、PCL、ODS、PostScript、以及Office Excel不同版本如，version97-2003，version2007，version2010，version2013，version2016等。

import com.spire.xls.*;

public class ExcelToImg {
    public static void main(String[] args) {
        //加載Excel工作表
        Workbook wb = new Workbook();
        wb.loadFromFile("test.xlsx");

        //獲取工作表
        Worksheet sheet = wb.getWorksheets().get(0);

        //調用方法將Excel工作表保存為圖片
        sheet.saveToImage("ToImg.png");
        //調用方法，將指定Excel單元格數據范圍保存為圖片
        //sheet.saveToImage("ToImg2.png",8,1,30,7);

        //調用方法將Excel保存為HTML
        sheet.saveToHtml("ToHtml.html");

        //調用方法將Excel保存為XPS
        sheet.saveToFile("ToXPS.xps", String.valueOf(FileFormat.XPS));

        //調用方法將Excel保存為CSV
        sheet.saveToFile("ToCSV.csv", String.valueOf(FileFormat.CSV));

        //調用方法將Excel保存為XML
        sheet.saveToFile("ToXML.xml", String.valueOf(FileFormat.XML));

        //調用方法將Excel保存為PostScript
        sheet.saveToFile("ToPostScript.postscript", String.valueOf(FileFormat.PostScript));

        //調用方法將Excel保存為PCL
        sheet.saveToFile("ToPCL.pcl", String.valueOf(FileFormat.PCL));

    }
}

三、項目中基於Spire.Doc封裝工具類實現Word轉換Pdf

直接上示例代碼

package com.demo.utils;

import com.spire.doc.Document;
import com.spire.doc.FileFormat;

public class WordToPdfUtil {

    public static void changeWordToPdf(String infile, String outFile) {
        //加載word示例文檔
        Document document = new Document();
        document.loadFromFile(infile, FileFormat.Docx);
        //保存結果文件
        document.saveToFile(outFile, FileFormat.PDF);
        document.close();
    }
}
