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).

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);

?>
