Re: [fontforge-users] More on glyphs transformation: scaling

[Mauro S. <mau...@gm...>]

Precise better. I used my font to show the current situation, another 
font to show the type of alignment I wanted to produce. I'm sorry if the 
two images have generated confusion. By default my font uses old style 
numbers even in superscript. I want to create superior number lining 
instead. I have generated both letters and numbers with the Element -- 
Style function, and for numbers I used tnum (uppercase) as the source. 
The superior numbers so generated are much higher than the glyphs of the 
letters as "x" etc. Therefore my intention is to establish for these 
numbers in superscript the same height as the lowercase letters "x" and 
of course align the baseline of these numbers to the letters. So: if I 
want a glyph of a certain height to be scaled to be equal to one of 
different height, what kind of accounts should I do?

thank you!
