Translation effect in Y direction. See attribute f. concat(m1, m2) Calculate the matrix product m1 * m2 and store the result in the current matrix. Any of m1 or m2 may be the current matrix. Be aware that matrix matrix multiplication is not commutative. So the sequence of m1, m2 is important. Parameters • m1 (Matrix) – First (left) matrix. • m2 (Matrix) – Second (right) matrix. 278 Chapter 22. Classes PyMuPDF (among objects of the same class!) is possible: if r1, r2 are rectangles and m1, m2 are matrices, you can do this (r1 + r2) * m1 * m2. • For all objects of the same class, a + b + c == (a + b) + c == a +
