BasicStroke
with the specified
attributes.
width
- the width of this BasicStroke
. The
width must be greater than or equal to 0.0f. If width is
set to 0.0f, the stroke is rendered as the thinnest
possible line for the target device and the antialias
hint setting.cap
- the decoration of the ends of a BasicStroke
join
- the decoration applied where path segments meetmiterlimit
- the limit to trim the miter join. The miterlimit
must be greater than or equal to 1.0f.dash
- the array representing the dashing patterndash_phase
- the offset to start the dashing pattern
