{Bridging scientific publication accessibility: \LaTeX--markup--\PDF\ alignment}
{This paper introduces a method aimed at enhancing the accessibility of 
scientific publications across multiple formats. Prior initiatives have 
predominantly centered on transforming \LaTeX\ source code or \PDF\
documents into markup languages like \XML\ and Markdown. However, such 
methods typically overlook the preservation of the visual layout 
inherent in \PDF\ pages.

The approach in this paper exploits the color properties in \LaTeX\ code
to maintain consistency and alignment between the visual presentation of
documents in \PDF\ format and the digital presentation of markup languages
and \LaTeX\ code. This strategy not only fills in the gaps of previous
approaches, but also promotes the integration and accessibility of
scientific document formats.}
