Direct Conclusion
The main difficulties in PDF translation come from the format itself, not the language conversion.
Common Issues
- 01Disordered paragraph sequence
- 02Broken table structures
- 03Incorrect restoration of multi-column content
Root Causes
- 01PDF stores page coordinates only, not logical structure
- 02Text, tables, and graphics are stored disjointedly in the file
- 03Translation tools often only extract plain text
Effective Countermeasures
- 01Parse the logical structure of the PDF first
- 02Distinguish between content types like body text, tables, and notes
- 03Complete translation and reflow within the structural layer
Final Judgment
The essential problem of PDF translation is structure understanding, not translation accuracy itself.
