BLOCK GRAPHICS
The block graphics, ASCII codes 225 to 255, are a series of
squares, triangles, and intersecting
lines. When they are put
together,
they form simple graphic designs and decorative
embellishments.
The 6 x 6 matrices are designed to print continuously
(meaning "next to each other"), so Gemini does not add any extra
spacing
between
these
characters,
as it does
for the
alphanumerics.
The Gemini can now print in a bidirectional mode (ESC U 0),
-
which cancels unidirectional
printing and returns to the faster
(standard)
bidirectional
printing
mode or it can print
in
unidirectional
mode (ESC U 1). In this mode all subsequent lines
are printed in unidirectional
mode. This mode is invoked by the
super/subscript
mode and by the graphic mode.
The Building Blocks
-
In the last chapter, we used block graphics to create oversized
letters in Figure 6-4. Let's consider that example again, this time
with discussion of the program listing.
