acter header parameters are described in the next section.
1.
Font type
is set to 0 for 7-bit character sets, or 1 for
8-bit character sets (see following table).
2.
Baseline height
is the distance in dots between the top
of the cell and the character baseline, between zero
and one dot less than the cell height.
3.
Cell width
and
height
are the width and height, re-
spectively, of the basic cell within which all character
definitions fall, between 1 and
255.
4.
Orientation
is set to 0 for portrait mode, or 1 for
landscape mode.
5.
Fixed/Proportional
is set to 0 for fixed spaced fonts,
or 1 for proportionally spaced fonts.
6.
Character Set
is a code computed from the escape
sequence which would be used to specify the same
font (see below),
7.
Pitch
is computed as the desired horizontal spacing
in dots, multiplied by four. For example, a lO-pitch
font would have a value of
120
(4 x
300/
10). The
range of valid values is 2 to
1260,
including those
values representing fractional dots.
8.
Height
is computed as the font height in dots, multi-
plied by four, in the range 0 to
10922.
Values repre-
senting fractional dots are valid. This height should
approximately equal the point size of the font, since
the height is compared with size parameters during
font definition.
9.
Style
is set to 0 for upright fonts, or 1 for italic fonts.
