“A PDF is fundamentally a series of 'drawing instructions' rather than a continuous text flow, which often leads to text being physically fragmented and causes layout failures after translation.”

Root Cause Analysis

Deep Document Structure Analysis

O.Translator goes beyond simple text extraction, employing proprietary algorithms to recognize the PDF's visual structure. It can accurately determine the logical order of text blocks, intelligently merging sentences that are physically split—such as those spanning columns or wrapping around images—into complete sentences before translation.

Adaptive Layout Redrawing

After translation, the system dynamically adjusts font size and line spacing according to the text length of the target language (e.g., English to German becomes longer, while Chinese becomes shorter), ensuring absolute positional accuracy for charts, headers and footers, and background images.

Final Solution Summary

By employing a 'deconstruct first, redraw later' process, pixel-level layout restoration is achieved.
