Direct Conclusion
Whether text can be successfully extracted depends on whether the PDF is text-based or scanned.
Two Situations
- 01Text-based PDF: Text layer can be parsed directly
- 02Scanned PDF: Requires OCR recognition first
Key Steps
- 01Determine PDF type
- 02Extract or identify text content
- 03Process translation in the text layer
Notes
- 01Tables and multi-column content need separate processing
- 02Extraction order affects translation quality
Final Judgment
Correctly identifying the PDF type is the prerequisite for high-quality translation.
