矩阵

将变换矩阵应用于多边形:

    <polygon points="0,0 30,0 30,30 0,30" transform="matrix(1,0.6,-1.2,1,40,10)" />
</svg>

每个点(x, y)将通过应用矩阵(a,b,c,d,e,f)进行转换,如下所示:

┌ x_new ┐    ┌ a  c  e ┐ * ┌ x_old ┐   ┌ x_old * a + y_old * c + e ┐
└ y_new ┘ =  └ b  d  f ┘   │ y_old │ = └ x_old * b + y_old * d + f ┘
                           └   1   ┘

结果相当于

    <polygon points="40,10 70,28 34,58 4,40" />
