NAME ivd2dvi - convert a dvi-ivd file to a normal dvi file SYNOPSIS ivd2dvi [-Xv] [-b buffersize] [filename] DESCRIPTION An extension to TeX called TeX-XeT produces "dvi-ivd" files, which are similar to dvi files but include nonstandard commands calling for the "reflection" (horizontal reversal) of text. In general, dvi-ivd files cannot be processed by standard dvi drivers because the reflection commands are not recognized. ivd2dvi converts a dvi-ivd file to an equivalent dvi file, that is, to a file in which the necessary reflections are carried out using only standard dvi commands. The resulting file can be processed by any dvi driver. The dvi-ivd file to be processed is specified on the command line; if the named file cannot be found and contains no period following its rightmost slash, ".dvi" is appended and ivd2dvi tries again. Unlike most dvi processors, ivd2dvi is a true filter and reads its standard input if no file is specified. The dvi file produced by ivd2dvi is written to standard output. Since dvitype says only "unrecognized command!" about the reflection commands found in dvi-ivd files, ivd2dvi also performs careful error checking for proper use of these commands. OPTIONS -v Verbose mode. The number of each page is printed as it is processed. -b newbuffersize Change the size of ivd2dvi's buffers. ivd2dvi uses several internal buffers and cannot proceed if any overflows. When this happens, you should try again using -b to increase the buffer size. The default buffer size is 1024. -X Exact mode. In this mode, ivd2dvi attempts to process the input file without modification. The comment string is not updated, NOP commands are retained, and the maximum stack depth is copied from the input file if possible (this number is conservatively but imprecisely computed by TeX; normally ivd2dvi will substitute the exact value). As a result, dvi files with no reflection commands are more likely to emerge totally unchanged. Use of this flag is discouraged except for debugging. ENVIRONMENT TEXFONTS Colon-separated list of directories to be searched for font metric files. The default is /usr/lib/tex/fonts. FILES /usr/lib/tex/fonts/*.tfm Font metric files.
