Detailed Description

cairo_matrix_t: : xx component of the affine transformation : yx component of the affine transformation : xy component of the affine transformation : yy component of the affine transformation : X translation component of the affine transformation : Y translation component of the affine transformation

A cairo_matrix_t holds an affine transformation, such as a scale, rotation, shear, or a combination of those. The transformation of a point (x, y) is given by: <programlisting> x_new = xx * x + xy * y + x0; y_new = yx * x + yy * y + y0; </programlisting>
