hi there, I wonder why this vector graph is **not** extracted by pymupdf4llm.to\_markdown(“uart.pdf”, write\_images=True) as images.

I’ve found this comment, according to his word about the detection of “significant” vector graph, this **should** be detected. because inside the rectangle there are texts instead of being empty.

This is the original pdf and the diagram is on page 5.

Strange, I agree I can’t see the drawings in the MD content ( I ensure to have `ignore_graphics=False` ) , however if I do:

```auto
page = doc[4]
page.get_drawings()

for drawing in drawings:
    print(drawing)

```

I can get the drawing info okay. Need to investigate what is going on with PyMuDPF4LLM here …

Aha - I am appreciating the answer in the issue here too - [[Bug] A specific diagram recognized as significant is not extracted as images by pymupdf4llm.to\_markdown · Issue #296 · pymupdf/RAG · GitHub](https://github.com/pymupdf/RAG/issues/296#issuecomment-3089023887) 🙂

There is a bug in pymupdf4lm obviously. We usually ignore fill-only vectors (have no borders) that have the same color as the page background. Which is white in this case.
