Re: [Rlib-devel] making text output page aware

[Bob D. <bd...@si...>]

Nabil,

You now want to look @ 

static void rlib_txt_end_part(rlib *r, struct rlib_part *part)
in txt.c to make the "top" and "bottom" paginate correctly.

As for the get_output_size it is based upon the current font's dpi.

Cheers,

- Bob
