hitex – A TeX extension writing HINT output for on-screen reading

An extension of TeX which generates HINT output.

The HINT file format is an alternative to the DVI and PDF formats which was designed specifically for on-screen reading of documents. Especially on mobile devices, reading DVI or PDF documents can be cumbersome. Mobile devices are available in a large variety of sizes but typically are not large enough to display documents formated for a4/letter-size paper. To compensate for the limitations of a small screen, users are used to alternating between landscape (few long lines) and portrait (more short lines) mode.

The HINT format supports variable and varying screen sizes, leveraging the ability of TeX to format a document for nearly-arbitrary values of \hsize and \vsize.
