Warning
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。 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 ). |
