Reads a Usenix FaceSaver(tm) file as input. Produces a portable graymap
as output.
FaceSaver(tm) files sometimes have rectangular pixels. While _f_s_t_o_p_g_m
won't re-scale them into square pixels for you, it will give you the
precise _p_n_m_s_c_a_l_e command that will do the job. Because of this, reading
a FaceSaver(tm) image is a two-step process. First you do:
fstopgm > /dev/null
This will tell you whether you need to use _p_n_m_s_c_a_l_e. Then use one of the
following pipelines:
fstopgm | pgmnorm
fstopgm | pnmscale -whatever | pgmnorm
To go to PBM, you want something more like one of these:
fstopgm | pnmenlarge -3 | pgmnorm | pgmtopbm
fstopgm | pnmenlarge -3 | pnmscale -whatever | pgmnorm | pgmtopbm
You want to enlarge when going to a bitmap because otherwise you lose
information; but enlarging by more than 3 does not look good.
