WebThe transformation matrix must initially be the identity transform. It may then be adjusted using the transformation methods. The transform (m11, m12, m21, m22, dx, dy) method must multiply the current transformation matrix with the matrix described by − m11 m21 dx m12 m22 dy 0 0 1 WebThe transform () method replaces the current transformation matrix. It multiplies the current transformation matrix with the matrix described by: In other words, the transform () method lets you scale, rotate, move, and skew the current context. Note: The transformation will only affect drawings made after the transform () method is called.
