Text Internals

As described in Part 1 (TextOverview TextOverview), the central text object in MuPDF is fz_text. It represents blocks of bidirectional text, carrying (potentially) both details of the underlying unicode characters, and the specific glyphs to be used to render them.

$\begin{lstlisting} typedef struct fz_text_s fz_text; \end{lstlisting}$

Text objects are reference counted, with the implicit understanding that once more than one reference exists to an object, it will no longer be modified.
