swfshape::drawcurve() draws a quadratic curve
(using the current line style,set by swfshape::setline())
from the current pen position to the relative position
(anchorx
,anchory
)
using relative control point
(controlx
,controly
).
That is, head towards the control point, then smoothly turn to the
anchor point.
With 6 parameters, it draws a cubic bezier to point
(x+targetdx
, x+targetdy
)
with control points (x+controldx
,
y+controldy
) and
(x+anchordx
, y+anchordy
).
