pdf 转 jpg

该方法是 pdf 的每一页，分别生成一个 jpg 文件

例：pdf 有6页 ======生成jpg======> 6个jpg文件，分别对应pdf的各页面

依赖

XML 复制代码

        <dependency>
            <groupId>org.apache.pdfbox</groupId>
            <artifactId>pdfbox</artifactId>
            <version>2.0.13</version>
        </dependency>

函数

直接返回 File

java 复制代码

    /**
     * pdf 转 jpg 返回文件
     *
     * @param path  文件路径
     * @return
     * @throws IOException
     */
    private static File pdfToJpg(String path) throws IOException {
        File file = File.createTempFile("newImg", ".jpg");
        PDDocument document = PDDocument.load(new File(path));
        PDFRenderer pdfRenderer = new PDFRenderer(document);
        for (int page = 0; page < document.getNumberOfPages(); ++page) {
            BufferedImage bim = pdfRenderer.renderImageWithDPI(page, 300, ImageType.RGB);
            ImageIO.write(bim, "jpg", file);
        }
        return file;
    }

扩展

1、直接生成到指定路径下

java 复制代码

        PDDocument document = PDDocument.load(new File("pdfPath"));
        PDFRenderer pdfRenderer = new PDFRenderer(document);
        for (int page = 0; page < document.getNumberOfPages(); ++page) {
            BufferedImage bim = pdfRenderer.renderImageWithDPI(page, 300, ImageType.RGB);
            ImageIO.write(bim, "jpg", new FileOutputStream("路径"));
        }

2、其他自己想吧
