Aspect ratio parameter specifies ratio of height of character
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. high X 15 in. 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
A s p e c t Ratio
1
P a p e r Ratio
Angle

Rotation
0
E x e c u t i n g 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.
