The first (unnumbered) release of vpl2vpl thus did not -implement the -b option allowed for mkt1font (to block the use of -predefined accented characters). I have since become aware that in -the rather rare case of an afm file containing composite character -information, afm2tfm uses that information to build definitions of -accented characters; I have therefore introduced a -b option in -version 0.1. - -There were two bugs in the coding dealing with the -s option in the -first version of vpl2vpl. First, the shrink-factor specified by the -user was incorrectly applied to the underdot accent as well as to -dropped superscript accents. Second, the shrink-factor was not -correctly scaled in terms of the value of DESIGNUNITS (this chiefly -affected Computer Modern fonts). Both of these have been fixed in -version 0.1. - -Another bug affected those characters (quotesingle, quotedbl, -backslash, underscore, braceleft, bar and braceright) which -dvips.enc places in the lower half of the character set, but which -vpl2vpl removes to make room for the normal TeX inhabitants of their -"slots"; in the first version of the program it was not possible to -include these characters in the output font. This has also been -fixed in version 0.1. - -The handling of LIGTABLE information controlling kerning etc. has -been improved, to eliminate repeated instructions and "orphaned" -instructions with no LABEL. - -In the first version of vpl2vpl I deliberately did not allow for -double superscript accents on tall characters such as capital -letters, on the grounds that this would be bad typographic practice. -A specific request for one such character has led me to modify -version 0.1 of the program to make the creation of such characters -possible, but I would still argue against their use. - -Some minor improvements have been made to the code in various areas, -including checking for inappropriate input, calculation of italic -correction for characters with superscript accents, and placing of -dropped superscript accents. (However, it is likely that such -accents will still sometimes require manual intervention.) - - -Changes to mkt1font between first (unnumbered) release and release 0.1 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -In the first release of mkt1font, kerning information for predefined -accented characters was taken from the input font, even if the -b -option had been specified to force the redefinition of such -characters. This has been fixed in version 0.1: if the -b option is -used, kerns for characters such as "eacute" are generalised from the -kerns for "e" in just the same way as happens for "emacron" etc. - -Similarly, predefined accented characters eliminated by the -b -option used to retain "ghost" entries among the unencoded characters -in the afm file. This too has been fixed in version 0.1. - -As of version 0.1, any composite character definitions contained in -the afm file of the input font are eliminated from the output font, -since they will almost certainly be incomplete, and (if the user has -specified -b) will probably be wrong as well. - -Version 0.1 can now properly process input fonts using MS-DOS file -format (with newline represented by CR/LF). It can also process -fonts in which the character "|" is used in the names of the -frequently used "noaccess def" and "noaccess put" definitions -(previously this fell foul of Perl's regular expression handler). - -As with vpl2vpl, I have modified version 0.1 of mkt1font to permit -the creation of tall characters bearing double superscript accents, -though I do not recommend the use of such characters. - -The "FontBBox" entries in the afm and pfb files now reflect any -increase in the maximum height or depth of characters in the output -font. - -Various other minor improvements have been made to the code, -including the placing of dropped superscript accents. (As with -vpl2vpl, however, it is likely that such accents will still -sometimes require manual intervention.) - - -Changes to vpl2vpl and mkt1font between release 0.1 and release 0.2 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -A. Changes common to both programs -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -I have implemented the candrabindu ("moon-dot") accent sometimes -used in Indian-language material. This is achieved by overprinting a -breve with a dotaccent; a new command-line option (-c) has been -introduced to allow for font-specific adjustments in the placing of -the dotaccent. - -The user's command-line is now stored as a comment at the head of -the output file(s). - -The constraint on the ordering of definitions in a definition file -has been removed: it is no longer necessary to ensure that a -character is defined before it is used. - -Digraphs are now implemented: if the character specified as the -"accent" in a definition is not in fact a valid accent character, -the definition is interpreted as a request for a digraph formed from -the "character" followed by the "accent". - -A bug which placed superscript accents incorrectly over tall -characters already bearing "under" accents has been fixed. - -The vertical positioning of "under" accents has been adjusted: they -are now placed slightly lower than previously. - - -B. Changes to vpl2vpl -~~~~~~~~~~~~~~~~~~~~~ - -Fixed a bug which resulted in some accents in small caps fonts being -positioned at the wrong height. - -Fixed a bug which resulted in small amounts of LIGTABLE information -being lost. - - -C. Changes to mkt1font -~~~~~~~~~~~~~~~~~~~~~~ - -The internal organisation of the program has been cleaned up in a -number of respects. In particular, various subroutines are now -called with the appropriate formal parameters, rather than relying -on the existence of equivalent global variables; the fetching and -storing of character metric information is tidier and more -efficient; and kerning information is dealt with in the course of -the main program loop, rather than in a private (double) loop -afterwards. - -The -s option allowing "under" accents to be shrunk by a specified -factor, which was previously available only in vpl2vpl, has now been -implemented in mkt1font also. - -The output afm file previously sometimes contained spurious entries -for unencoded characters that duplicated items in the list of -encoded characters. This has been fixed. - -Despite the fix introduced in version 0.1, some predefined kerning -information continued to find its way into the afm file even when -the -b option was specified to block the use of predefined accented -characters. A new, improved fix is now in place to prevent this. An -error in a regular expression which generated some undesirable kerns -has also been corrected. - -The "FontBBox" entries in the afm and pfb files now reflect any -increase in the maximum width of characters in the output font, as -well as increases in their maximum height or depth. - -Fixed a bug causing the underbar accent to be too long. - -Fixed a bug causing "under" accents to be assigned the wrong depth: -this could result in the bottom of the accent failing to print -properly. - - -Changes to vpl2vpl and mkt1font between release 0.2 and release 0.21 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Changes common to both programs -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The vertical positioning of "under" accents has been adjusted again -(the previous adjustment was a little too enthusiastic). They have -been raised slightly. - -The height at which characters are reckoned to be so tall that -superscript accents placed on them must be raised above the normal -level has been increased slightly (from 1.1 x xheight to 1.15 x -xheight). - -Changes to vpl2vpl and mkt1font between release 0.21 and release 0.211 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -A. Changes to vpl2vpl -~~~~~~~~~~~~~~~~~~~~~ - -A single minor change has been made to vpl2vpl: this has been -necessitated by a change in the format of the LIGTABLE information -produced by version 8.1 of afm2tfm, which now adds identificatory -comments to lines referring to characters by means of octal -notation. Vpl2vpl strips out such comments. - - -B. Changes to mkt1font -~~~~~~~~~~~~~~~~~~~~~~ - -Minor bugfixes have been put in place: extra spaces in the the -"noaccess def" and "noaccess put" definitions are now permitted, and -so is a character named ".null". An error message has been improved. - -Changes to vpl2vpl and mkt1font between release 0.211 and release 0.212 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -A. Changes to vpl2vpl -~~~~~~~~~~~~~~~~~~~~~ - -Fixed a bug in the "double superscript accent on small caps -character" routine. - - -B. Changes to mkt1font -~~~~~~~~~~~~~~~~~~~~~~ - -Fixed a bug which produced incorrect output in cases where the -character to be accented is defined as blank (e.g. space). - -Changes to vpl2vpl and mkt1font between release 0.212 and release 0.22 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Changes common to both programs -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The programs now recognise "commaaccent" as a valid subscript -accent. Note that they cannot replace this subscript with the -superscript form used with the letter "g" (any more than they can -substitute the apostrophe-like form of the caron that is used with -"L", "d", "l" and "t"). Note also that as there is no position for -this accent in either the standard TeX encoding or the dvips.enc -variant, vpl2vpl will not actually be able to use it to build new -characters without further modification. - -In the case where the definition file specifies, say, "z overdot" -and the font contains a predefined version named "zdotaccent", it -previously happened that the output font contained both characters. -This has been fixed: now only the character requested in the -definition file exists in the output. - -Changes to vpl2vpl and mkt1font between release 0.22 and release 0.221 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -A. Changes to mkt1font -~~~~~~~~~~~~~~~~~~~~~~ - -Fixed a bug which caused the program to fail after incorrectly -identifying CharStrings definitions. - -Changes to vpl2vpl and mkt1font between release 0.221 and release 0.222 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -A. Changes to mkt1font -~~~~~~~~~~~~~~~~~~~~~~ - -Changed FamilyName to remove only the final one of a number of -hyphenated elements from the font name. diff --git a/Master/texmf-dist/doc/fonts/accfonts/COPYING b/Master/texmf-dist/doc/fonts/accfonts/COPYING deleted file mode 100644 index a43ea2126fb..00000000000 --- a/Master/texmf-dist/doc/fonts/accfonts/COPYING +++ /dev/null @@ -1,339 +0,0 @@ - GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 675 Mass Ave, Cambridge, MA 02139, USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it.

You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) 19yy <name of author> - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Smith, University of Cambridge, 1997 - ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - - -These two programs address the same requirement using the same basic -algorithms: their aim is to make it easy to create versions of -existing fonts containing whatever accented characters the user may -need, arranged according to whatever encoding he/she may favour. -Mkt1font does this by reading in the two files that define a Type 1 -PostScript font and writing out new versions of them; vpl2vpl does -it by reading in the file that defines a TeX virtual font and -writing out a new version of it. In each case information about what -accented characters are required and where they should be located is -supplied by means of a simple definition file, which has the same -format for both programs. - -It is common to hear someone say, "I need a font containing -such-and-such special characters," when really they should be -saying, "I need a version of Times/Palatino/New Century Schoolbook -etc. containing the special characters for such-and-such a -language." If we are to take full advantage of computer typesetting -and desktop publishing, we need to be able to choose our fonts on -grounds of aesthetic merit rather than expediency, and to move -towards standardised encodings. These programs should go some way to -making this possible. - -Note that most Type 1 PostScript fonts are commercial products -subject to both copyright and licensing restrictions. If the license -for such a font forbids reverse-engineering it, it is presumably -illegal to run mkt1font on it; in any case it would certainly be a -serious breach of copyright to make modified versions of the font -available to third parties. The author of mkt1font will not be held -responsible for any such misuses of the software. (No such legal -problems surround the use of TeX virtual fonts, which merely specify -new ways to use existing fonts.) However, would-be users may wish to -note the existence of a body of high-quality freeware lookalikes for -many of the standard Type 1 fonts: like mkt1font and vpl2vpl, the -Ghostscript fonts developed by URW++ Design and Development -Incorporated are made available under the GNU General Public License -(see the file COPYING), which permits them to be modified and -redistributed provided that certain simple decencies are observed. -These fonts are available from many ftp sites, including those -forming the Comprehensive TeX Archive Network (CTAN), for example -ftp.tex.ac.uk: look for the most recent font archive file in the -directory /tex-archive/support/ghostscript/gnu/fonts. - -A detailed specification of the form of the definition file used by -mkt1font and vpl2vpl is given below in the instructions for using -the two programs, but it may be helpful to give a quick idea of its -contents here. Each line of the file contains something similar to -"128 x acute", which is an instruction to create a new character -formed from "x" with an acute accent and located at position 128 in -the character set. Once a new character has been defined in this -way, it "exists" in just the same way as any other character, under -the name "xacute" (or whatever); thus it can even receive further -accents. The two lines - - 129 e macron - 130 emacron breve - -will create a "long e" and a "long-or-short e" at the positions -specified. (If only the latter is desired, they can both be assigned -the same position in the encoding -- the second will overwrite the -first.) Subscript as well as superscript accents are available. Some -sample definition files are included to give an idea of the format: -note that two of these (CSX.def and Norman.def), used for Indian -language material in Roman script, contain the triple-accented -character "runderdotmacron acute"! - -In addition to accented characters proper, both programs can produce -digraphs -- single characters composed of pairs of other characters. -In itself this may seem to be of limited use, since the digraph -should always be indistinguishable from its two constituent -characters printed consecutively. However, some Unicode-style -encodings require that certain character-pairs be treated as -digraphs. In addition, use of a digraph in subsequent definitions -allows an accent to be applied to two characters as a pair: so, for -example, - - 131 k h - 131 kh underbar - -will produce a character consisting of an underlined "kh" at -position 131. - -The algorithms used in both programs take great care to secure the -most attractive results, placing accents centrally over/under their -characters at appropriate heights/depths, varying their position -according to the angle of slant in Italic and similar fonts, -providing new characters with kerning information (which will be -resolutely ignored by most word-processors), and -- in the case of -mkt1font -- giving hinting instructions to improve output on -low-resolution printers. However, users may feel that some -characters need "tweaking". This tends to happen when the part of -the character adjacent to the accent is highly asymmetrical: -subscript accents below "r" may need moving to the left, while -superscript accents above "d" may need moving to the right. It is -relatively easy to modify the output of vpl2vpl to make such -improvements by hand (vpl files are designed to be easy for humans -to read, and vpl2vpl identifies each character with a comment). Type -1 fonts are another matter; mkt1font generates a human-readable and -commented ".dis" file as well as the ".pfb" font file, and it is -possible to make changes to this and rebuild the pfb file with t1asm -(see below), but this is not quite as simple as modifying a TeX -virtual font. - -The programs are written in Perl, and have not been tested on -systems other than Unix. (Apart from the #! line at the top, the -only Unix specificities the author is aware of are two references to -"/dev/null" in mkt1font and the general assumption that filenames -can be of any length.) At run time, mkt1font invokes two further -font utilities, t1asm and t1disasm, written by I. Lee Hetherington -and available from CTAN ftp sites: look in the directory -/tex-archive/fonts/utilities/t1utils. If it is intended to use the -fonts output by mkt1font with Adobe Type Manager, it will probably -be necessary to create ".inf" and/or ".pfm" files for them: for this -there is a useful shareware program for MS-DOS called REFONT, which -can be found at http://www.asy.com/sharewr.htm. - -Detailed instructions for using the two programs follow.

A successful run will read a vpl (Virtual -Property List) file and a definition file, and will generate a new -vpl file on standard output. The input font is assumed to adhere to -the standard TeX encoding for text fonts unless it was created with -the program afm2tfm, in which case it is assumed to conform to 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 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. - -In the case of a non-virtual font (such as the Computer Modern -fonts), use a pl (Property List) file, created with the standard -utility tftopl, as the input file in place of a vpl file; vpl2vpl -will make the necessary changes on the fly. - -A typical complete sequence of commands to create a new virtual -font might therefore be - 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 -for a PostScript font, or - 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. - -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) .
