# Known Issues
|
|
|
|
|
|
-- Reading order is segmented based on rules, which can cause disordered sequences in some cases
|
|
|
-- Vertical text is not supported
|
|
|
-- Lists, code blocks, and table of contents are not yet supported in the layout model
|
|
|
+- 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.
