cairo_matrix_t

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>

cairo_matrix_t(xx, yx, xy, yy, x0, y0)

Arguments

xx

xx component of the affine transformation
yx

yx component of the affine transformation
xy

xy component of the affine transformation
yy

yy component of the affine transformation
x0

X translation component of the affine transformation
y0

Y translation component of the affine transformation
