Java - 将图像转换为 Word Doc

Question

正在创建屏幕截图，word doc 也有一些大小，但是当我打开它时它是空的...谁能建议，附上代码

我需要将我所有的屏幕截图放在 word 文档中。

在打开 word 文档时遇到一些“启用内容”错误，我已经信任发布者...现在该错误（当然不是错误）不会出现，但 WORD 文档是空的，大小合理。

            // }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    public static void captureScreenShot() throws Exception {

        XWPFDocument docx = new XWPFDocument();
        String screenshot_name = System.currentTimeMillis() + ".png";

        BufferedImage image = new Robot()
                .createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
        ImageIO.write(image, "png", new File("d:/xyz/" + screenshot_name));

        InputStream pic = new FileInputStream("d:/xyz/" + screenshot_name);
        docx.addPictureData(pic, Document.PICTURE_TYPE_PNG);
        FileOutputStream out = new FileOutputStream("d:/xyz/doc1.docx");
        docx.write(out);
        pic.close();
        out.flush();
        out.close();

        TimeUnit.SECONDS.sleep(1);
    }

}

修改您的 captureScreenShot 方法，如下所示，它将起作用。

public static void captureScreenShot() throws Exception {
    XWPFDocument docx = new XWPFDocument();
    XWPFParagraph paragraph = docx.createParagraph();    
    XWPFRun run = paragraph.createRun();
    String screenshot_name = System.currentTimeMillis() + ".png";
    BufferedImage image = new Robot()
            .createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
    ImageIO.write(image, "png", new File("d:/xyz/" + screenshot_name));
    InputStream pic = new FileInputStream("d:/xyz/" + screenshot_name);
    //docx.addPictureData(pic, Document.PICTURE_TYPE_PNG);
    run.addBreak();
    run.addPicture(pic, XWPFDocument.PICTURE_TYPE_JPEG, screenshot_name, Units.toEMU(350), Units.toEMU(350));
    pic.close();
    FileOutputStream out = new FileOutputStream("d:/xyz/doc1.docx");
    docx.write(out);
    out.flush();
    out.close();

    TimeUnit.SECONDS.sleep(1);
}
