A successful run will read a pl -(Property List) or vpl (Virtual Property List) file and a definition -file, and will generate a new vpl (Virtual Property List) file on -standard output. The input font is assumed to adhere to the standard -TeX encoding for text fonts unless it was created with either of the -programs afm2pl or afm2tfm, in which case it is assumed to conform to -(respectively) the Adobe Standard Encoding or the encoding specified -in the file dvips.enc. In either case, the name of the input font is -assumed to be the name of the input file without its .vpl or .pl -extension: it must conform to normal TeX conventions for naming fonts, -as vpl2vpl attempts to draw conclusions from it about the kind of font -it is dealing with. - -A typical complete sequence of commands to create a new virtual -font might therefore be - tftopl cmr10.tfm cmr10.pl - vpl2vpl -d ISO-Latin1.def cmr10.pl >cmr10_isol1.vpl - vptovf cmr10_isol1.vpl cmr10_isol1.vf cmr10_isol1.tfm -for a Computer Modern font, or - afm2pl Times-Roman.afm rptmr.pl - pltotf rptmr.pl rptmr.tfm - vpl2vpl -d ISO-Latin1.def rptmr.pl >ptmr-isol1.vpl - vptovf ptmr-isol1.vpl ptmr-isol1.vf ptmr-isol1.tfm -for a PostScript font. - -Another approach for a PostScript font is to use afm2tfm: - afm2tfm Times-Roman.afm -t dvips.enc -v ptmr rptmr - vpl2vpl -d ISO-Latin1.def ptmr.vpl >ptmr-isol1.vpl - vptovf ptmr-isol1.vpl ptmr-isol1.vf ptmr-isol1.tfm --- but this is now deprecated, as afm2tfm generates incorrect -values for the heights of some characters, and this can lead to -bad accent placing. - -In order to keep the whole upper half of the character set free for -the requirements of the encoding specified in the definition file, -certain modifications are made to input fonts following the -dvips.enc encoding to bring them into greater conformity with the -TeX norm. In particular, the characters dotaccent and hungarumlaut -are placed in the positions assigned by TeX (\"5F, \"7D), not those -enforced by dvips.enc (\"C7, \"CD). The f-ligatures, double quotes -and dashes are also moved from the upper half of the character set -to their normal TeX positions. As a result, the following characters -are not found in the lower half of the character set: quotesingle, -quotedbl, backslash, underscore, braceleft, bar, braceright. These -characters can, however, be assigned positions in the output font if -they are needed. (Indeed, they could all be explicitly restored to -their dvips.enc positions if this were desired.) - -Options: - - -d should refer to a font definition file. This file (which could - usefully be named, e.g., \"French.def\") should consist of - lines of character definitions, in the form - \"number\" \"character\" - or - \"number\" \"character\" \"accent\" - Here \"number\" represents the character's position in the new - encoding and may be expressed in decimal, octal or hex; - \"character\" names the character (e.g. \"comma\", \"eight\", - \"A\") or consists of the word \".notdef\" (indicating that - the specified number's \"slot\" in the new encoding is to be - empty); and \"accent\" optionally names an accent to be placed - on the character. In addition to the standard accents available - in PostScript fonts, \"underbar\" and \"underdot\" are also - available, as are \"under\" versions of all the normal - superscript accents (\"underdieresis\", \"underring\", etc.). - The Indian accent \"candrabindu\" may also be specified: it - is formed by overprinting a breve with a dotaccent. Finally, - \"overdot\" may be used as a synonym for \"dotaccent\". - - If the character named in the \"accent\" position is not in fact - a valid accent character, the program interprets the definition - as a request for a digraph formed from the \"character\" and the - \"accent\". A digraph consisting of, say, \"k\" and \"h\" will be - indistinguishable from the letters \"k\" and \"h\" printed - consecutively, but the digraph \"kh\" can itself receive accents - like any other character: see next paragraph. - - A new character (such as \"amacron\" or \"kh\") may be freely - used in the \"character\" position of a further definition (such - as \"amacron breve\" or \"kh underbar\"). There is no constraint - on the ordering of definitions within a definition file. The - definition of \"a macron\" does not have to precede that of - \"amacron breve\": requests for \"impossible\" characters are - deferred until their constituents have had a chance to come into - being. - - \"Slots\" for which no new definition is given retain the - definition they have in the input font. - - The definition file may also contain blank lines and comments - (introduced by \"\#\"). - - -s may optionally give the factor, expressed as a per-thousand - value, by which normally superscript accents (such as dieresis, - ring) should be shrunk when they are used as subscript accents - (such as underdieresis, underring). Values of around 800 may be - found useful. - - -c may optionally give two comma-separated numerical values to - adjust the x and y coordinates of the dotaccent placed within a - breve to form the candrabindu accent. A coordinate scheme using - \"DESIGNUNITS R 1000\" is assumed. - - -b may optionally be specified to block the use of predefined - accented characters, forcing vpl2vpl to define its own - versions. This may be useful to secure a consistent appearance - in cases where a font designer does not share vpl2vpl's views - on where accents should be placed. - - -h prints this help. -"; -#------------------------------------------------------------------------# - -######################## -# Packages and constants -######################## -# -use File::Basename; -use Getopt::Std; -$cmdline = basename($0) .
