Using FontLab 5, Windows.
I'm creating an OTF font from a few Type1 fonts. One of the type one fonts is a small cap font. To get the kerning pairs from the old Type1 font into my new font I thought I could pull the Type1 into FontLab and export the AFM file. Then open the AFM in a text editor and change all the lowercase characters to my small cap glyphs.
KPX A c -18
KPX A Csmall -18
where Csmall is the name of my small cap c. But it isn't working and I can't see why!
From the AFM file I'm also deleting all the kern pairs I won't need, like:
KPX A T -74
as it's already in there from having procesed the "regular" text.
When all my substitutions are made in the AFM file I change the StartKernPairs line to reflect the number of pairs I now have.
However, when I try to import the modified AFM into FontLab it doesn't import any kern pairs, even if I tell it to completely replace them. I'm able to import kerning from other AFM files but I don't see any difference in structure between the ones that import and the one that won't. What am I missing?
Thanks for any insight
