The following figure illustrates a squared-off, inverted-U pattern (one line up,
one over, and one down). The pattern repeats every one unit, and each unit
is 0.5 high and wide.
This pattern would be defined as follows:
*IUS,Inverted U's
90, 0,0, 0,1, .5,-.5
0, 0,.5, 0,1, .5,-.5
270, .5,.5, 0,1, .5,-.5
The first line (the up bar) is a simple dashed line with 0,0 origin. The second
line (the top bar) should begin at the end of the up bar, so its origin is 0,.5.
The third line (the down bar) must start at the end of the top bar, which is at
.5,.5 for the first instance of the pattern, so its origin is at this point. The third
line of the pattern could be the following:
90, .5,0, 0,1, .5,-.5
or
270, .5,1, 0,1, -.5,.5
The dashed pattern starts at the origin points and continues in the vector
direction given by the angle specification. Therefore, two dashed-line families
that are opposed 180 degrees are not alike. Two solid-line families are alike.
The following pattern creates six-pointed stars.
