Returns new CairoMatrix object. Matrices are used throughout cairo to convert between different coordinate spaces.
Sets matrix to be the affine transformation given by xx, yx, xy, yy, x0, y0. The transformation is given by:
x_new = xx * x + xy * y + x0; and y_new = yx * x + yy * y + y0;
&reftitle.parameters;
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
&reftitle.returnvalues;
Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.
