Identity#

Identity is a Matrix that performs no action – to be used whenever the syntax requires a matrix, but no actual transformation should take place. It has the form fitz.Matrix(1, 0, 0, 1, 0, 0).

Identity is a constant, an “immutable” object. So, all of its matrix properties are read-only and its methods are disabled.

If you need a mutable identity matrix as a starting point, use one of the following statements:

>>> m = fitz.Matrix(1, 0, 0, 1, 0, 0)  # specify the values
>>> m = fitz.Matrix(1, 1)              # use scaling by factor 1
>>> m = fitz.Matrix(0)                 # use rotation by zero degrees
>>> m = fitz.Matrix(fitz.Identity)     # make a copy of Identity
