我在网上找了一个例子

用的时候会出现如下信息

2011-12-28 13:27:31,218 INFO [org.apache.pdfbox.pdmodel.font.PDCIDFontType2Font] - Can't read the embedded font Times New Roman
2011-12-28 13:27:31,218 INFO [org.apache.pdfbox.pdmodel.font.PDCIDFontType2Font] - Using font Times New Roman instead
2011-12-28 13:27:31,234 INFO [org.apache.pdfbox.pdmodel.font.PDCIDFontType2Font] - Can't read the embedded font SimSun
2011-12-28 13:27:31,234 INFO [org.apache.pdfbox.pdmodel.font.PDCIDFontType2Font] - Using font SimSun instead

不过还能正常使用下面是代码

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Iterator;
import java.util.List;
import javax.imageio.IIOImage;
import javax.imageio.ImageIO;
import javax.imageio.ImageWriter;
import javax.imageio.stream.ImageOutputStream;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
public class PdfToImg
{
public static void main(String[] args) throws IOException {
         PDDocument doc = PDDocument.load("c:\t1.pdf");
         int pageCount = doc.getPageCount();
         System.out.println(pageCount);
         List pages = doc.getDocumentCatalog().getAllPages();
         for(int i=0;i<pages.size();i++){
             PDPage page = (PDPage)pages.get(i);
             BufferedImage image = page.convertToImage();
             Iterator iter = ImageIO.getImageWritersBySuffix("jpg");
             ImageWriter writer = (ImageWriter)iter.next();
             File outFile = new File(System.getProperty("user.dir")+"\pdfPicFile\test"+i+".jpg");
             System.out.println(System.getProperty("user.dir")+i+".jpg");
             FileOutputStream out = new FileOutputStream(outFile);
             ImageOutputStream outImage = ImageIO.createImageOutputStream(out);
             writer.setOutput(outImage);
             writer.write(new IIOImage(image,null,null));
         }
         doc.close();
         System.out.println("over");
     }
}
