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. |
