## Description

PDFMathTranslate is a document translation tool designed to convert technical and scientific files into multiple languages while preserving their original visual layout. It functions as a specialized processor for academic research papers, ensuring that complex mathematical notation and technical formatting remain intact throughout the translation process.

The system utilizes a layout-preserving parsing engine that extracts text and structural metadata while maintaining the spatial coordinates of every document element. To handle the translation of technical content, it employs an intermediate markup representation that separates text from styling, allowing for the isolation of LaTeX-formatted equations. An asynchronous orchestration layer manages concurrent requests to external translation services, tracking individual document segments to ensure accurate final assembly.

The tool features a bilingual layout engine capable of generating side-by-side or integrated dual-language output files. By injecting translated text back into the original coordinate system, the software reconstructs the final document to match the visual structure of the source file, including the alignment of images and tables.
