Description

Bug

Docling cannot obtain the images inserted into the text box of docx file

Steps to reproduce

  1. download the zip from https://www.3gpp.org/ftp/tsg_ran/WG1_RL1/TSGR1_124b/Docs/R1-2602023.zip , unzip this zip file and then you can get
    a file named R1-2602023_Discussion on other aspects of CSI acquisition for 6GR.docx
  2. use docling to convert the docx to markdown file
            cmd = [
                "docling",
                "--from", "docx",
                "--to", "md",
                "--output", os.path.dirname(md_path),
                doc_path
            ]

            print(f"run command: {' '.join(cmd)}")
            result = subprocess.run(
                cmd,
                capture_output=True,
                text=True,
                check=True
            )
  1. I get the markdown, I have obtained the markdown file and carefully compared the contents of the docx file and the markdown file (I use typora to read markdown file).
  2. I found the error. The details are as follows: The display effect of the markdown file is as follows:
The display effect of the docx file is as follows:

Research direction
Investigate how Docling extracts images from docx files, particularly images inside text boxes. Start by examining the docx parser module in the docling codebase (likely in docling/document/converter.py or similar). Look for existing image extraction logic and identify where text boxes are handled. Use the provided sample document (R1-2602023 Discussion on other aspects of CSI acquisition for 6GR.docx) to reproduce the issue and trace the parsing flow. Check if there is a missing handler for images within text boxes compared to regular inline images.
