Gouvea" <fqgouvea@colby.edu> +Subject: inverse limit symbol + +I've been trying to make an "inverse limit" symbol. This should be a usual +lim, with a left-pointing arrow under it, and it should be a "math operator +with limits", that is, one should be able to write something like \ilim_n +and get + + lim + <-- + n + +with, of course, the right spacing and so on. + +I've been trying to build on LaTeX with the AMS macros to do this. So far, +my attempts have come out pretty bad. The first was + +\DeclareMathOperator*{\ilim}{\underleftarrow{\mathrm{lim}}} + +which puts the arrow far too close to the "lim". Plus, the arrow doesn't +come out straight! + +Then I tried something like this: + +\newcommand{\ilim}[1]{% + \displaystyle{% + \lim_{\genfrac{}{}{0pt}{}{\longleftarrow}{\scriptstyle #1}} }\;} + +which sort of does it by brute force (and requires the "wrong" syntax +\ilim{n}, but I can live with that). The arrow doesn't look right, however: +it seems to be broken in the middle. + +Before I spend more time on this, I thought I'd check... perhaps someone +out there has already solved it. Any suggestions? + +- -- + +Fernando Q.

The files are bundled into either psibycus.tgz +or psibycus.zip, to suit the convenience of both the elect and the +infidel. This is a preliminary release, because the font is still +largely unhinted. I will ultimately provide a rather thorough +set of hints, since the primary purpose for making up this font +was to get away from the crude bitmap scaling that is all you +can get out of PDF readers. Hinting, however, is even worse than +filing matrices. It is a soul-destroying bore, and I cannot do +very much of it at any given session. The absence of hints will +not be noticed at resolutions of 600dpi and above. The font has a +private UniqueID in the open range for now, but a registered +UniqueID will be applied for. + +The original METAFONT realization of ibycus4 remains the controlling +form of the font. The TeX user will see absolutely no difference +in the set-widths of the Type1 font because the TFM file for it is +exactly the same as the TFM file for the METAFONT version. (In a +Unix environment, they could be joined by hard or symbolic links.) + +The Type1 control points have been derived from METAFONT log output +generated by "tracingspecs". This is not impossible, as has sometimes +been claimed, but it does take work. + +The bundle consists of: + +1. IbycusHTG-Regular.pfa ( = fibr.pfa = IBYHTGR_.PFB ). + The character designs are Silvio Levi's. Some small differences + in accent positioning and vertical positioning on the classic + METAFONT typeface grid have been allowed. My own lowercase lunate + sigma has been improved. These changes will ultimately be read + back into the ibycus4 METAFONT source. + +2. fibr.tfm (identical with fibr84.tfm). The use of the Type1 font + is specified by calling on fibr, rather than fibr84. Obliqued and + bold versions of the font are still exclusively METAFONT. + They will continue to be invoked as fibo84[89]? and fibb84[89]? + until I make up Type1 versions of them (if I ever do). + +3. fibr.vf, which serves to provide a reference into a dvips map + file. The raw TFM for this VF file is fibr84.tfm, which has the + interesting effect of making METAFONT generated PK files a + fail-safe alternative when the dvips map lookup fails. + The checksums for fibr.tfm fibr84.tfm and fibr.vf are identical. + This is arbitrary, since fibr.vf has integer escapement values + rounded from the METAFONT values in the tfm files. + +4. config.iby and iby.map. The iby.map file shows how to associate + fibr84 with IbycusHTG-Regular. + fibr84 IbycusHTG-Regular <IbycusHTG-Regular.pfa + or + fibr84 IbycusHTG-Regular <fibr.pfa + This line can be copied into psfonts.map for general use. + +5. IbycusHTG-Regular.afm and IbycusHTG.enc. These are provided for + information only. The AFM file contains only the character info + and the pair-kerning data. There is no point in going further + since the Adobe convention for AFM is incapable of specifying the + ligature sequences needed for ibycus4. The encoding file could + supply both ligatures and pair-kerns, but to what purpose? + +6. Various TeX input files rewritten to use the fibr invocation in + place of the fibr84 invocation. (This is the only change that + users will need to make, other than installing the above files in + the TEXMF directory tree). + +IbycusHTG-Regular is licensed without charge for use in the creation of +documents in all media, in accordance with the included copyright +notice. Users are welcome and indeed encouraged to adapt the font +to other typesetting systems. Note that iota subscript is applied to +the affected vowel as a following zero-width character kerned +drastically to the left. (Other well-known Polytonic Greek fonts +do the same thing. This trick saves many, many glyph spaces for more +constructive use.) + + mackay@cs.washington.edu Pierre A.
