T9. hgt mag Height magnifier, 1-7 (times). Use a magnifier of 1 with
proportionally spaced fonts, because characters lose
smoothness at higher magnifications.
T10. wid mag Width magnifier, 1-7 (times). Proportionally spaced fonts do
not have a set width. To estimate the size of your field, use
the letter "W" for the widest field or an "L" for an average
width field. Find your selected font and the desired width in
Appendix B, "Fonts."
T11. color Options for standard printer fonts:
There are two types of field color overlay attributes:
Transparent
Opaque
Field placement in the packet is an important consideration
when using field color attributes, because fields are imaged in
the order they are received. If a line field is defined before
the overlay (text or constant text) field, the line field is
blocked out by the overlay field, depending on the overlay
field's color attribute. If a line field is defined after the overlay
field, the line field is not blocked out by the overlay field,
regardless of the overlay field's color attribute.
B Opaque, Normal, Black, Normal
D Opaque, Normal, White, Normal
O Transparent, Normal, Black, Normal
R Opaque, Normal, White, Normal
W Opaque, Normal, White, Normal
The overlay field (text or constant text) does
not block out (or "erase") existing fields.
The overlay field blocks out (or "erases")
