# SWFShape::drawCurve

Draws a curve (relative)

### Description

int SWFShape::drawCurve ( float `$controldx` , float `$controldy` , float `$anchordx` , float `$anchordy` [, float `$targetdx` ], float `$targetdy` )
Warning

This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.

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`).
