MSDN's example default template for an Expander uses M 0 4 L 4 0 L 8 4 Z

MSDN的示例扩展器的默认模板使用m0 4 l4 0 l8 4z

Most path's start with the letter "M" and an x,y coordinate, followed by line segments which are identified by a Character followed by space-delminited numbers for parameters, and end with the letter "Z". So M 0 4 L 4 0 L 8 4 Z means

大多数路径以字母“M”和x、y坐标开头，然后是行段，这些行段由字符标识，后面是空格分隔的数字作为参数，最后是字母“Z”。所以m0 4 L 4 0 L 8 4 Z。

• start at 0,4
• 从0开始,4
• draw a Line up to 4,0
• 画一条直线到(4,0
• draw a Line down to 8,4
• 画一条线到8 4。
• then end the Path
• 然后结束路径
