Form-Filled PDF extractions

### Question
## How can I ensure that form filled data is present in the images of the PDF pages?

Hi there,

I am attempting to use Docling as part of an attribute extraction framework. I need to be able to handle attributes that may be inputted in form filled PDFs. I have seen that this is possible to extract the form filled data when outputting as markdown, when I have this as my pipeline parameter with a python implementation:

-- Set up pipeline options with the given resolution
pipeline_options = PdfPipelineOptions()
pipeline_options.do_ocr = True
pipeline_options.do_table_structure = True
pipeline_options.table_structure_options.do_cell_matching = True
pipeline_options.images_scale = resolution
pipeline_options.generate_page_images = True
pipeline_options.generate_picture_images = True
pipeline_options.table_structure_options.mode = TableFormerMode.ACCURATE
pipeline_options.ocr_options = RapidOcrOptions()

-- Initialize document converter
doc_converter = DocumentConverter(
format_options={InputFormat.PDF: PdfFormatOption(pipeline_options=pipeline_options)}
)

-- Convert the input file
conversion_result = doc_converter.convert(input_file)

-- Save the JSON representation of the document
docling_doc = conversion_result.document
json_output_path = os.path.join(docling_folder, "doc.json")
with open(json_output_path, "w") as fp:
fp.write(json.dumps(docling_doc.export_to_dict()))

-- Save the Markdown file
markdown_content = conversion_result.document.export_to_markdown(image_mode='EMBEDDED')
markdown_output_path = os.path.join(markdown_folder, f"{pdf_name}.md")
with open(markdown_output_path, "w") as fp:
fp.write(markdown_content)

-- Save images for each page
for page_no, page in conversion_result.document.pages.items():
page_image_filename = os.path.join(image_folder, f"{pdf_name}-page-{page_no}.png")
with open(page_image_filename, "wb") as fp:
page.image.pil_image.save(fp, format="PNG")

I have found that:

pipeline_options.table_structure_options.do_cell_matching = True

means it will be present in the markdown (despite the form filled aspect of this pdf not being a table).

However, when I extract images of the pages of the PDF, this form filled data is missing, and I am missing all the attributes I am looking to extract.

Is there a way that I can ensure that the form filled data will be present in the images of the pdf pages? Are there parameters in the pipeline that would enable this?

Thanks
