Statement
Aspect ratio parameter specifies ratio of height of character
c s i z - Cont
to its width. For example, an aspect ratio of 2 specifies
characters that are twice as high as they are wide. An aspect
ratio of 1 specifies square characters.
Paper ratio parameter specifies ratio of height of scaling
area to its width. Scaling area is defined by scaling points
P1 and P2. For example, 10 in.(25.4cm) high X 15 in. (38.1
cm) wide scaling area has paper ratio of 10:15 or 2:3.
Angle of rotation parameter specifies direction in which char-
acters are printed. Direction is expressed as angle (measured
left) between line of print and X-axis, as shown below.
Parameter is expressed in current angular units (degrees,
radians, or grads).
Default values for four parameters are as follows:
1.5%
Height
2
Aspect ratio
1
Paper ratio
Angle
of
rotation
0
Executing csiz statement without parameters sets default
values.
These values are also set when plotter is initialized
or cleared ( p c l r ) .
T h e f o l l o w i n g e x a m p l e p r o g r a m u s e s c s i z instruction (line 3)
to specify character dimensions and shape and rotate lettering
direction through entire circle in 10-degree intervals. Plot
statement (line 2) centers pen for each printing sequence.
