使用 Apache POI 从文档中获取图像 [英] Get Image from the document using Apache POI

问题描述

我正在使用 Apache Poi 从 docx 读取图像.

I am using Apache Poi to read images from docx.

这是我的代码:

enter code here

public Image ReadImg(int imageid) throws IOException {
    XWPFDocument doc = new XWPFDocument(new FileInputStream("import.docx"));
    BufferedImage jpg = null;
    List<XWPFPictureData> pic = doc.getAllPictures();
    XWPFPictureData pict = pic.get(imageid);
    String extract = pict.suggestFileExtension();
    byte[] data = pict.getData();
    //try to read image data using javax.imageio.* (JDK 1.4+)
    jpg = ImageIO.read(new ByteArrayInputStream(data));
    return jpg;
}

它可以正确读取图像，但不是按顺序读取.

It reads images properly but not in order wise.

例如，如果文档包含

image1.jpeg图像2.jpeg图像3.jpegimage4.jpegimage5.jpeg

image1.jpeg image2.jpeg image3.jpeg image4.jpeg image5.jpeg

读起来

图片4图像3图片1图像5图片2

image4 image3 image1 image5 image2

你能帮我解决吗?

我想按顺序阅读图像.

谢谢，西提克

推荐答案

public static void extractImages(XWPFDocument docx) {
    try {

        List<XWPFPictureData> piclist = docx.getAllPictures();
        // traverse through the list and write each image to a file
        Iterator<XWPFPictureData> iterator = piclist.iterator();
        int i = 0;
        while (iterator.hasNext()) {
            XWPFPictureData pic = iterator.next();
            byte[] bytepic = pic.getData();
            BufferedImage imag = ImageIO.read(new ByteArrayInputStream(bytepic));
            ImageIO.write(imag, "jpg", new File("D:/imagefromword/" + pic.getFileName()));
            i++;
        }

    } catch (Exception e) {
        System.exit(-1);
    }

}
