FontLab TypoAscender and TypoDescender warning  Mans's picture
I'm surprised no-one has asked this before on Typophile (my
search at least yielded no results). When generating fonts in
FontLab I often get the message:  [WARNING] The feature file
OS/2 overrides TypoAscender and TypoDescender do not sum to the
font bbox size!  I assume this has to do with the metrics
settings somehow, but no matter how I play around with the
metrics this message won't go away.  O ye wise, what is wrong,
how did I cause it, and how do I make it go away?  Cristobal
Henestrosa's picture  It has been asked many times, but the
Search function is not working properly at this moment. Try in
Google. A related thread here:  Mans's picture  Christobal,
thanks! I thought I had seen it somewhere.  oldnick's picture
The referenced thread notwithstanding, in my experience the
message goes away if, on the "Most important font dimensions"
page, simply make the Ascender and the Descender AS A POSITIVE
value equal the UPM (e.g., 750+250=1,000)
