返答の最終案
Hello, Sergey.
OK, I understand what your problem is.
SIE translates SVG arc command into cubic Bezier curves, because VML arc
command cannot render a transformed arc.In my opinion, you should consider the possibility of
this translation to cubic Bezier, if you desire to emulate SVG arc
command by VML.please see the SIE code. (http://sourceforge.jp/projects/sie/svn/view/trunk/sie.js?view=markup&revision=1598&root=sie)
>STArc.prototype.set = function starcset(x1, y1, rx, ry, psai, fA, fS, x4, y4) {
>...
> this.D = (this.D ? this.D.concat(nea) : nea);
> nea = null;
> return true;
>};Each argument 'x1, y1, rx, ry, psai, fA, fS, x4, y4' is a parameter of SVG arc command.
'this.D' is a set of parameters of cubic Bezier curves.Additionally, I show the example of coordinate transformation performed
in SIE. For example, please think of this simple SVG:SIE analyzes this SVG and creates a current transformation matrix (CTM)
for a rotation of 60 degree. SIE transforms the coordinates of each point
using this matrix, and then generates the following VML.
