Face header

[Tomas Butkus]

Hi,

I'm new in FreeType. Can anyone tell me how to get maximum y (yMax) and
minimum y (yMin) of all chars in CharMap?
Another one question. When i retrieve face properties:

face_properties.horizontal->Line_Gap;
face_properties.horizontal->Ascender;
face_properties.horizontal->Descender;

these sizes are with what parameters (resolution, fontsize)?

Actualy i need find particular font with particular size height (including
line spacing, max height of chars). Is there another, better or simpler
way?

thanks in advance
