Gouvea" 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.

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
