- Known Issues
- ============
- - Reading order is based on the model’s sorting of text distribution in
- space, which may become disordered under extremely complex layouts.
- - Vertical text is not supported.
- - Tables of contents and lists are recognized through rules; a few
- uncommon list formats may not be identified.
- - Only one level of headings is supported; hierarchical heading levels
- are currently not supported.
- - Code blocks are not yet supported in the layout model.
- - Comic books, art books, elementary school textbooks, and exercise
- books are not well-parsed yet
- - Enabling OCR may produce better results in PDFs with a high density
- of formulas
- - If you are processing PDFs with a large number of formulas, it is
- strongly recommended to enable the OCR function. When using PyMuPDF
- to extract text, overlapping text lines can occur, leading to
- inaccurate formula insertion positions.
