Display features
18.2.1
F
LASH
This attribute is valid from the time set until end of row or
otherwise modified.
Flashing causes the foreground colour pixels to be
displayed as background pixels. This means that the
fringing, if set, will only be visible when the foreground
colour pixels are displayed as foreground colour. The flash
frequency can be set to either 1 or 2 Hz (see
Section 18.4.5).
18.2.2
F
RINGING
This attribute is valid from the time set until end of row or
otherwise modified.
Fringing causes an edge (fringe) to be put around the
foreground pixels. Fringing is an attribute that can be
applied to characters providing a shadow around the
shape of the foreground information. The fringe is 1 line
wide in the vertical direction and 1 pixel wide in the
horizontal direction. Fringing applies to all characters
except those in columns 8 and 9.
The size of the fringe is independent of the size attributes
and always remains 1 scan-line vertically and 1 pixel
horizontally for even and odd field.
Fringing is only effective within the text area and will not
extend over the text area borders. Fringing will cross the
borders of boxes in the horizontal direction, but will not
cross between rows in the vertical direction. Special
facilities are provided for combined characters (see
Section 18.10).
18.2.3
S
IZE
Two sizes are offered in both horizontal and vertical
directions. The sizes available are normal, double
height/width and any combinations of these. The attribute
settings are always valid for a whole row. Mixing of sizes
within a row is not possible. The first character in the row
must be the serial attribute, Mode 1 if the default of normal
size is to be overridden. These attributes will be ignored in
any other position. For additional details see
Section 18.3.2.
18.2.4
I
TALICS
This attribute is valid from the time set until end of row or
otherwise modified
.
This attribute causes the character
foreground pixels to be offset horizontally by 1 pixel per
4 scan-lines (interlaced mode); see Fig.14.
The base is the bottom left character matrix pixel.
The pattern of the character will be indented 1 pixel every
2 scan-lines per field, starting from the base of the
character. Fringing is shifted accordingly.
18.2.5
P
ROPORTIONAL SPACING
The character font ROM in column A, contains the
half-width characters: f, i, j, l and t. These characters have
a width of only 6 pixels instead of the normal 12. Examples
of half-width characters are shown in Fig.15.
If some of the characters are not used for depicting narrow
characters they may be used as normal. In this case they
are accessible via column D (see Fig.27).
