Get content-type of the embedded image inside Docx

[pr20080798]

Hi Team,

We need to read the content type of the embedded images while parsing the DOCX file. This data we need to upload in database for further functionality.

if(node.getDocumentObjectType().equals(DocumentObjectType.Picture)) { // Node is element of paragraph collection
DocPicture picture = (DocPicture) childObj;
// Able to read the image here
}

Please help to get the content-type of any image like png, jgp, bmp etc.

Thank you

Hello,

Thanks for your inquiry!

Please refer to the following code to get the content type of the embedded images while parsing the DOCX file.

Code: Select all

        Document doc = new Document();
        doc.loadFromFile("Doc1.docx");
       
        for(int i = 0; i < doc.getSections().getCount(); i++)
        {
            Section sec = doc.getSections().get(i);
           
            for(int j = 0; j < sec.getParagraphs().getCount(); j++)
            {
                Paragraph para = sec.getParagraphs().get(j);
                for(int k = 0; k < para.getChildObjects().getCount(); k++)
                {
                    DocumentObject obj = para.getChildObjects().get(k);
                    if (obj.getDocumentObjectType() == DocumentObjectType.Picture)
                    {
                        DocPicture pic = (DocPicture)obj;
                        byte[] imageByte = pic.getImageBytes();

                        InputStream inputStream = new BufferedInputStream(new ByteArrayInputStream(imageByte));
                        String mimeType = URLConnection.guessContentTypeFromStream(inputStream);
                        System.out.println(mimeType);
                       
                    }
                }
            }
        }


If the code does not meet your needs, please provide us with your input file for further investigation. Thanks in advance.

Thank you for the response.

Can we get the file format also to know whether it is .png or .jpg?

                        ByteArrayInputStream byteArrayInputStream = null;
                        MemoryCacheImageInputStream memoryCacheImageInputStream = null;
                        byteArrayInputStream = new ByteArrayInputStream(imageByte);
                        memoryCacheImageInputStream = new MemoryCacheImageInputStream(byteArrayInputStream);
                        Iterator<ImageReader> iterator = ImageIO.getImageReaders(memoryCacheImageInputStream);
                       
                        if (iterator.hasNext()) {
                        ImageReader reader = (ImageReader) iterator.next();
                        String imageFormat = reader.getFormatName();
                        System.out.println(imageFormat);
                        }else {
                           System.out.println("image data wrong!");
                  }
                    }
                }
