Sony CCD-TRV608 - Manual (Page 171)

It is not possible to define a line pattern for shapes other
than circles, squares, and rounded squares. Also,
selecting no pattern (in the upper left hand corner of the
pattern palette) will effectively get rid of any color
settings.
The line pattern can't be defined when a polygon or a
straight line is selected in the shape list.
Line Click to define an outline to the shape.
Line thickness
The line thickness can be changed by defining a
numerical line point size.
A value of '0' is invalid. To prevent the outline from
appearing at all, set the value to 1 and set white as the
color.
