I think it's a useful insight for people working on RAG using LLMs.
Devs working on RAG have to decide between parsing PDFs or using computer vision or both.
The author of the blog works on PdfPig, a framework to parse PDFs. It seems to rely on combining computer vision with PDF metadata for its document understanding APIs. https://github.com/UglyToad/PdfPig/wiki/Document-Layout-Anal...
GP's comment says a pure computer vision approach may be more effective in real-world scenarios, which is an interesting insight since many devs would assume that pure computer vision is probably the less capable but also more complex approach.
As for comments suggesting relying on the parsing library itself instead of rasterizing, the reason is that detecting high-level visual objects (like tables , headings, and illustrations) and getting their coordinates using vision models is far easier that trying to infer those structures by examining hundreds of PDF line, text, glyph, and other low-level PDF objects. I feel these commentators have never tried raw PDF parsing. Try it once using PdfBox, Fitz, etc. You'll understand the difficulty. PDF really is a terrible format!
