Beware that at least BlueSky fonts has buggy AFMs. Appreantly the
converter was not following MF rules and it produced more then one
kerning pair (KPX) entries for some glyphs.
E.g. cmr12.afm gives:
KPX k a -54.396
KPX k a -27.197
which is obviously an error. Here's the roman.mf:
ligtable "k": if serifs: "v": "a" kern -u#, fi\\"w": "e" kern k#,
"a" kern k#, "o" kern k#, "c" kern k#;
Reading this is not for mere mortals, so let's examine output of
In LIGTABLE we have (uwe: in pl files notation 'C x' means literal
(LABEL C k)
(LABEL C v)
(KRN C a R -0.054398) <--
(LABEL C w)
(KRN C e R -0.027199)
(KRN C a R -0.027199) <--
(KRN C o R -0.027199)
(KRN C c R -0.027199)
My understanding of the Appendix F of MFbook is that ligtable program
stops on first match, so for (k,a) the correct kerning is -0.054398.
But apparently the converter was buggy. The fix is to remove all the
duplicates except first (adjusting StartKernpairs line accordingly).
Depending on the program that you feed AFMs to, this might be ok, give
you a wrong kerning or give you an error message about duplicate KPX.
Actually, that's how I found it - a user of Lout batch formatter
reported that Lout complains about BlueSky fonts.
Yes - I tried to report this problem but never heard back.
