Java实现pdf转图片

pdf转图片
创建一个maven项目
添加icepdf依赖

<!-- https://mvnrepository.com/artifact/org.icepdf.os/icepdf-core -->
<dependency>
      <groupId>org.icepdf.os</groupId>
      <artifactId>icepdf-core</artifactId>
      <version>6.2.2</version>
  </dependency>

代码实现如下：

import java.awt.image.BufferedImage;
import java.awt.image.RenderedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import org.icepdf.core.pobjects.Document;
import org.icepdf.core.util.GraphicsRenderingHints;

/**

public class IcePdf {
    public static void pdf2Pic(String pdfPath, String path) throws Exception {
        Document document = new Document();
        document.setFile(pdfPath);
        //缩放比例
        float scale = 2.5f;
        //旋转角度
        float rotation = 0f;

        for (int i = 0; i < document.getNumberOfPages(); i++) {
            BufferedImage image = (BufferedImage)
                    document.getPageImage(i, GraphicsRenderingHints.SCREEN, org.icepdf.core.pobjects.Page.BOUNDARY_CROPBOX, rotation, scale);
            RenderedImage rendImage = image;
            try {
                String imgName = i + ".png";
                System.out.println(imgName);
                File file = new File(path + imgName);
                ImageIO.write(rendImage, "png", file);
            } catch (IOException e) {
                e.printStackTrace();
            }
            image.flush();
        }
        document.dispose();
    }
    public static void main(String[] args) throws Exception {
        String filePath = "D:\\Code\\pdf2pic\\src\\main\\resources\\检测报告.pdf";
        pdf2Pic(filePath, "D:\\Code\\pdf2pic\\src\\main\\resources\\");
    }
