I need to convert some VML to the equivalent of svg, and I need to understand how to calculate the Rx and Ry from arcsize.
As I understand arcsize of VML is the percentage of half size of smaller segment, but what represent the measure, the chord subtended to the arc?
In svg I know rx and ry are the radius, but from what starting point? and why 2 radius?
I need a conversion explanation with a math formula or an example script in any language.
