curve (Bezier Curve)

This element is used to draw a cubic bézier curve.

The following properties of the style attribute are ignored:

• top

• margin-top

• center-y

• left

• margin-left

• center-x

• width

• height

[Example: The following specifies a simple curve that opens upward:

<v:curve id="mycurve"  
from="10pt,10pt" to="100pt,10pt"  
control1="40pt,30pt" control2="85pt,30pt">  
</v:curve>  

This shape is created:
