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
).
