IZE
The size of the characters can be modified in both the
horizontal and vertical directions.
CC:
Two sizes are available in both the horizontal and
vertical directions. The sizes available are normal (
×
1),
double (
×
2) height/width and any combination of these.
The attribute setting is always valid for the whole row.
Mixing of sizes within a row is not possible.
TXT:
Three horizontal sizes are available normal (
×
1),
double (
×
2) and quadruple (
×
4). The control characters
‘normal size’ (0CH/BCH) enables normal size, the ‘double
width’ or ‘double size’ (0EH/BEH/0FH/BFH) enables
double width characters.
Any two consecutive combination of ‘double width’ or
‘double size’ (0EH/BEH/0FH/BFH) activates quadruple
width characters, provided quadruple width characters are
enabled by TXT4.QUAD WIDTH ENABLE.
Three vertical sizes are available normal (
×
1), double (
×
2)
and quadruple (
×
4). The control characters ‘normal size’
(0CH/BCH) enable normal size, the ‘double height’ or
‘double size’ (0DH/BDH/0FH/BFH) enable double height
characters. Quadruple height characters are achieved by
using double height characters and setting the global
attributes TXT7.DOUBLE HEIGHT (expand) and
TXT7.BOTTOM/TOP.
If double height characters are used in Teletext mode,
single height characters in the lower row of the double
height character are automatically disabled.
18.3.4
I
TALIC
CC:
This attribute is valid from the time set until the end of
the row or otherwise modified. The attribute causes the
character foreground pixels to be offset horizontally by
1 pixel per 4 scan lines (interlaced mode). The base is the
bottom left character matrix pixel. The pattern of the
character is indented as shown in Fig.17.
TXT:
The Italic attribute is not available.
