for those new this all this, "anchor" is where you want to end up and "control" is the point you would go to if you were drawing a square.
for example, this would draw a quarter circle
<?php
$s->movePenTo(100, 100);
$s->drawLineTo(200, 100);
$s->drawCurveTo(200, 200, 100, 200);
$s->drawLineTo(100, 100);
?>
SWFShape::drawCurveTo
(PHP 5 < 5.3.0, PECL ming SVN)
SWFShape::drawCurveTo — Draws a curve
Description
SWFShape::drawCurveTo
( float
$controlx
, float $controly
, float $anchorx
, float $anchory
[, float $targetx
], float $targety
) : intWarning
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::drawcurveto() draws a quadratic curve
(using the current line style, set by swfshape::setline())
from the current pen position to
(anchorx,anchory)
using (controlx,controly)
as a control point. That is, head towards the control point,
then smoothly turn to the anchor point.
With 6 parameters, it draws a cubic bezier to point
(targetx, targety)
with control points (controlx,
controly) and
(anchorx, anchory).
