adjusting a font size to fit it in a box

[Idigoras Inaki]

Hello,

I am working with the Freetype engine and I have a problem:

I want to fit the font size to a box. I am given the box size (in pixels) to
where I have to write text (only one line); how can I get the font size to
make sure that all chars of that font (glyphs) fit in the box?

I thought that the True Type header´s yMin and yMax ( or the horizontal
header´s ascent and descent) could be used, but I do not know what these
values are related to.

So, to make it clear, I want to know the font size (points) to call
TT_New_Instance(...) making sure that all glyphs will fit in the box, and
the size is the maximum possible (the highest font will touch the box´s
upper bound and the lowest will touch the bottom bound). Most often the
highest char I use is the 'Ñ' character (N with slash).

Thanks in advance. I am looking forward to hearing from you,
