hom_mat2d_identity — Generate the homogeneous transformation matrix of the identical 2D transformation.
hom_mat2d_identity( : : : HomMat2DIdentity)
hom_mat2d_identity generates the homogeneous transformation matrix HomMat2DIdentity describing the identical 2D transformation:
Note that homogeneous matrices are stored row-by-row as a tuple; the last row is not stored because it is identical for all homogeneous matrices that describe an affine transformation. Thus, HomMat2DIdentity is stored as the tuple [1,0,0,0,1,0].
hom_mat2d_identity always returns 2 (H_MSG_TRUE).
