Leading Pango Metrics

[Alex Vazquez <avazquez dev gmail com>]

Hi! I have a question about get metrics of a font.

If I don't understand wrong the height of a font is ascent+descent+leading.

with pango I can get ascent and descent but i can't get the leading.

I try calculate the leading with  pango_layout_get_spacing() but this value get me 0.

Also I try get leading with pango_layout_get_pixel_size() but the result is ascent + descent.

I'm using as a font "Purisa"

Can i calculate the leading of a font using pango ? 

Regards!
