Adobe Illustrator Artwork文件格式，版本3

Question

我有一个旧的“Adobe Illustrator艺术品文件”，文件格式版本为3：

253 -433 m
253 -465.0325 227.0325 -491 195 -491 c
162.9675 -491 137 -465.0325 137 -433 c
137 -400.9675 162.9675 -375 195 -375 c
227.0325 -375 253 -400.9675 253 -433 c
b

在文件中添加一个简单的圆圈会添加以下代码：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DropDownList ddList= e.Row.FindControl("ddl_Project_Owner") as DropDownList;
            if (ddList != null)
            {
                string sqlStr = "Select distinct Project_Owner from tblProjectHealth order by Project_Owner";
                DataSet ds = new DataSet();

                conn.Open();
                SqlCommand cmd = new SqlCommand(sqlStr, conn);
                SqlDataAdapter ad = new SqlDataAdapter(cmd);
                ad.Fill(ds);

                ddList.DataSource = ds;
                ddList.DataTextField = "Project_Owner";
                ddList.DataValueField = "Project_Owner";
                ddList.DataBind();


            }
        }
    }

我在哪里可以找到这个规格？特别是画一个圆圈。

我只需找到给定半径的圆，并改变其半径。 怎么做？
