FMGETFONTINFO(3W)FMGETFONTINFO(3W)NAMEfmgetfontinfo - return information about the overall font
SYNOPSIS
#include <fmclient.h>
long fmgetfontinfo(fh, info)
fmfonthandle fh;
fmfontinfo *info;
DESCRIPTIONfmgetfontinfo writes information to the members of the fmfontinfo type
structure pointed to by the info parameter. The information written
pertains to the whole fh font. If fmgetfontinfo cannot find the fh font,
its returned function value is -1. Otherwise the value of the function
is 0.
The members of fmfontinfo are declared to make it easy for FORTRAN
programmers to access and interpret (hence the large number of long
declarations). For a listing of the entire fmfontinfo type structure,
see <fmclient.h>. The members most likely to be of interest are:
printermatched : tells whether there is a printer widths file
corresponding to this font.
matrix00-matrix11 : floats that provide information in points.
fixed_width : tells whether all the characters in the font are the same
width.
xorig, yorig : the aggregate x-origin and y-origin of the font. yorig is
the positive distance between the baseline and the lowest descender.
xorig is the distance (positive or negative) from the current point to
the start of imaging of the glyph.
xsize, ysize : the maximum sizes of the characters in the font, in
pixels.
height : often the same as ysize, but some fonts lie to get more leading.
nglyphs : the index of the highest-numbered character. It is not the
total number of characters, but when allocating space for
fmgetwholemetrics, use nglyphs as though it were the total number of
characters. In other words, this is the highest index of a possibly
sparse matrix.
The other members of the fmfontinfo type structure are self-explanatory.
