Fabrice Popineau Fabrice Popineau supelec fr Editor s note This article is an adaptation of the HTML file that comes with the current version 0 40 of windvi Why another Windows dvi viewer Note that throughout this document when I say Win32 this means Windows 9x and Windows NT There are many previewers for dvi files under Win32 The most popular is probably Dviwin by H Sendoukas However it lacks some important features o the ability to recursively search directories for font files o the ability to use vf files or display PostScript fonts Unfortunately the Dviwin sources were never put into the public domain on the other side of the fence Xdvi un der Unix has these features is widely used and its sources are available Xdvi k uses the kpathsea library to search directories already used in the Web2c win32 port of TeX so there was some interest in porting Xdvi k to Win32 As it turned out this turned into far more than just a port as X Windows is far from Win32 All the user interface and the graphical part has been rewritten For the future when the base functionality of Xdvi k is available and stable under Win32 we can expect to add the interesting features of Dviwin to Windvi Features The most important features of Windvi are as follows o monochrome or grey scale bitmaps antialiasing for fonts O easy navigation through the dvi file page by page with different increments by 5 or
