Matrices are used throughout cairo to convert between different coordinate spaces. A :class:`Matrix` holds an affine transformation, such as a scale, rotation, shear, or a combination of these. The transformation of a point (x,y) is given by:: x_new = xx * x + xy * y + x0 y_new = yx * x + yy * y + y0 The current transformation matrix of a :class:`Context`, represented as a :class:`Matrix`, defines the transformation from user-space coordinates to device-space coordinates. See :meth:`Context.get_matrix` and :meth:`Context.set_matrix`. The default values produce an identity matrix. Matrices can be compared with ``m1 == m2`` and ``m2 != m2`` as well as multiplied with ``m3 = m1 * m2``. c tjd|_tj|j||||||y)Nzcairo_matrix_t *)rnew_pointerrcairo_matrix_init)selfxxyxxyyyx0y0s l/home/developers/rajanand/mypropertyqr-fmb-refixing-v2/venv/lib/python3.12/site-packages/cairocffi/matrix.py__init__zMatrix.__init__'s1 23   r2r2r2FcT|}tj|j||S)aReturn a new :class:`Matrix` for a transformation that rotates by ``radians``. :type radians: float :param radians: Angle of rotation, in radians.

This is similar to :meth:`transform_point` except that the translation components of the transformation are ignored. The calculation of the returned vector is as follows:: dx2 = dx1 * xx + dy1 * xy dy2 = dx1 * yx + dy1 * yy Affine transformations are position invariant, so the same vector always transforms to the same vector. If ``(x1, y1)`` transforms to ``(x2, y2)`` then ``(x1 + dx1, y1 + dy1)`` will transform to ``(x1 + dx2, y1 + dy2)`` for all values of ``x1`` and ``x2``. :param dx: X component of a distance vector. :param dy: Y component of a distance vector. :type dx: float :type dy: float :returns: A ``(new_dx, new_dy)`` tuple of floats. rPrQr)rr rcairo_matrix_transform_distancer rS)r dxdyrs rtransform_distancezMatrix.transform_distances@.WW[2r( + --dmmR!VR!VLRyrc,tfdfddS)Nc0t|jSr)r$)r names rz,Matrix._component_property..s5rc2t|j|Sr))setattrr )r valuer^s rr_z,Matrix._component_property..s tU Crz8Read-write attribute access to a single float component.)doc)property)r^s`r_component_propertyzMatrix._component_propertys 5 CJL Lrr rrrrr)rrQrQrrQrQr))r5 __module__ __qualname____doc__r classmethodrrr"r'r+r0r3r7r;__mul__r@rErHrKrNrVr[rer rrrrrrrrrs.G$@,H%331 G<&80:. @  6L T "B T "B T "B T "B T "B T "BrrN)rhrrrobjectrrkrrrns  ('kVkr
