Empty "graphics" attribute in to_markdown() function

[tuv-jan-hery]

Problem Summary: I am using pymupdf4llm.to_markdown() to extract content from a PDF, but I noticed that the "graphics" attribute in the metadata remains empty, even though a vector graphic is expected.

According to the API documentation, the attribute is described as follows: ”graphics” - a list of vector graphics rectangles on the page. This is a list of boundary boxes of clustered vector graphics as delivered by method Page.cluster_drawings(). When trying to use this aforementioned PyMuPDF method separately (see code below), I'm able to retrieve the expected vector graphic.

Expected Behavior: The "graphics" attribute in the Markdown metadata should list the detected vector graphics, consistent with what Page.cluster_drawings() return.

Actual Behavior: Despite the presence of vector graphics, the "graphics" field remains empty in the Markdown output.

Versions:

• PyMuPDF: 1.25.5
• pymupdf4llm: 0.0.19

Code:

import pymupdf
import pymupdf4llm

file_path = "../assets/TestDoc.pdf"

doc = pymupdf.open(file_path)  # Explicitly open with PyMuPDF
page = doc[1]
vector_dic_paths = page.get_drawings()
clusters = page.cluster_drawings(drawings=vector_dic_paths, x_tolerance=3, y_tolerance=3)
print(f"Manually found {len(clusters)} clustered vector graphics.") # Finding one clustered vector on second page of PDF.

md_text = pymupdf4llm.to_markdown(
    doc,
    write_images=True,
    image_path="./extracted_images",
    page_chunks=True,
    force_text=True,
    extract_words=False
)
print(md_text) # Empty "graphics" attribute for the second page of the PDF.

This post is not actionable for two reasons:

1. This is a potential for package https://github.com/pymupdf/RAG - not PyMuPDF itself.
2. You did supply a file reproducing the error - which is mandatory.

@JorjMcKie Thank you for the quick feedback and sorry for the mistakes. I uploaded the document, would it be possible for you to move the ticket?

Currently, the list of detected clusters of vector graphics is intentionally empty and will be populated at a later point in time.
