SWFShape->drawCurveTo() — Draws a curve

Descrizione

SWFShape
int drawCurveTo ( int $controlx , int $controly , int $anchorx , int $anchory [, int $targetx ], int $targety )
Avviso

Questa funzione è SPERIMENTALE. Ovvero, il comportamento di questa funzione, il nome di questa funzione, in definitiva tutto ciò che è documentato qui può cambiare nei futuri rilasci del PHP senza preavviso. Siete avvisati, l'uso di questa funzione è a vostro rischio.

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);
?>
