Direct Conclusion
The key to generating a bilingual PDF is not just superimposing two languages, but maintaining a clear correspondence in the same layout.
Common Practices
Common bilingual comparison methods include top-bottom comparison, left-right comparison, and original-translation pagination comparison.
Main Difficulties
- 01Changes in text length after translation can lead to paragraph misalignment
- 02Tables and lists are difficult to correspond one-to-one in comparison mode
- 03Line height and line breaking rules differ significantly between languages
Reliable Implementation
- 01Use paragraphs or sentences as the minimum alignment unit
- 02Lock the original structure during the translation process
- 03Unify layout rules during the rendering phase
Final Judgment
A truly usable bilingual PDF should allow readers to intuitively see the correspondence between the original and the translation without having to search back and forth.
