Another way of approaching the problem is by using graphical page displays. The page is rendered into a page-description language such as postscript or PDF. Internet browsers, aided by an external viewer or plug-in can then display the page in its integrity, including any mathematical formulae within it. When using this method, documents are displayed with exactly the same layout as the original documents, which could be TEX documents for instance. The printing resolution is also maintained at a high quality level.
But using an external viewer or plug-in involves everyone possessing a copy. A viewer also requires a verbose and large file format including all the non-standard fonts used. Just in the same way as the embedded graphics display, any mathematics contained within these documents looses its semantic value, as well as the possibility to edit it or modify it.
These interim solutions have only contributed to the problem by putting in evidence the need of a consistent standardized methodology for the transmission of mathematics via the World Wide Web.
