FMSCALEFONT(3W)FMSCALEFONT(3W)NAMEfmscalefont - scale a font face.
SYNOPSIS
#include <fmclient.h>
fmfonthandle fmscalefont(fh, scale)
fmfonthandle fh;
double scale;
DESCRIPTION
fmfindfont returns a handle to a 1-point-high font in the face specified.
fmscalefont applies the provided scale factor to the matrix associated
with this instance of the font, returning a new handle. Later, when the
font is imaged, this value is used to determine the size of characters to
use. Its default coordinate system is in points, so passing a scale of
"12" creates a specification of a 12-point font. This is display-
resolution independent. Its functionality parallels the scalefont
operator of PostScript.
If fmscalefont is not able to scale a specified font, it returns a value
of zero (0).

NOTES
Subsequent use of any of the routines discussed on the fmmatrix man page
can cause a different transformation of the font to be either described
(by fmgetfontinfo or fmprstr) or imaged. The page matrix is always
concatenated with the font matrix before imaging a string or giving out
information about a font.
NOTE
This routine is available only in immediate mode.
