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. + +SEE ALSO + "Mixing right-to-left texts with left-to-right texts," Donald Knuth + and Pierre MacKay, TUGboat volume 8 (1987), number 1, pp. 14--25. + +AUTHOR + Larry Denenberg, larry@bbn.com or larry@harvard.edu. |
