pdf转图片

1.引入jar包

<dependency>    <groupId>org.apache.pdfbox</groupId>    <artifactId>fontbox</artifactId>    <version>2.0.9</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.pdfbox/pdfbox --><dependency>    <groupId>org.apache.pdfbox</groupId>    <artifactId>pdfbox</artifactId>    <version>2.0.9</version></dependency>2.编写代码测试

@Testpublic void contextLoads() {    String fileAddress="C:\\Users\\intasect\\Desktop\\测试";    pdf2png(fileAddress,"kafka消息接口文档","jpg");

}public static void pdf2png(String fileAddress,String filename,String type) {    // 将pdf装图片 并且自定义图片得格式大小    File file = new File(fileAddress+"\\"+filename+".pdf");    try {        PDDocument doc = PDDocument.load(file);        PDFRenderer renderer = new PDFRenderer(doc);        int pageCount = doc.getNumberOfPages();        for (int i = 0; i < pageCount; i++) {            BufferedImage image = renderer.renderImageWithDPI(i, 144); // Windows native DPI            // BufferedImage srcImage = resize(image, 240, 240);//产生缩略图            ImageIO.write(image, type, new File(fileAddress+"\\"+filename+"_"+(i+1)+"."+type));        }    } catch (IOException e) {        e.printStackTrace();    }}3.结果
