TK画布画圆弧请教

h97252

my $arc = $canvas->createArc(40, 40, 80, 100);

这个语句画出的圆弧，是有2边半径加一段圆弧组成的图纸，我只想要画出那圆弧段，不要显示2边半径。

参数怎么设定?搞不懂，请教高手，给个范例！谢谢！

-style type
Specifies how to draw the arc. If type is pieslice (the default) then the arc's region is defined by a section of the oval's perimeter plus two line segments, one between the center of the oval and each end of the perimeter section. If type is chord then the arc's region is defined by a section of the oval's perimeter plus a single line segment connecting the two end points of the perimeter section. If type is arc then the arc's region consists of a section of the perimeter alone. In this last case the -fill option is ignored.

这是 tcl/tk 的文档， perl/Tk 的 API 应该类似
