arrlp.transform_matrix module

arrlp.transform_matrix(shape=None, *, shiftx=0.0, shifty=0.0, shearx=0.0, sheary=0.0, angle=0.0, scalex=1.0, scaley=1.0, stacks=False)

Defines the 3x3 transformation matrix for affine transformation in 2D.

Parameters:

• shape (int or tuple or np.ndarray) – Describes the shape of the coordinates. If int, all dimensions will have this value. If tuple, corresponds to the shape.

• shiftx (float) – Shift value in x

• shifty (float) – Shift value in y

• shearx (float) – Shear value in x

• sheary (float) – Shear value in y

• angle (float) – Rotation angle [°]

• scalex (float) – Scale value in x

• scaley (float) – Scale value in y

Examples

>>> from arrlp import transform_matrix
...
>>> matrix = transform_matrix(shape, shiftx=2, shifty=3.4)
