Matrix.init_
void init_(double xx, double yx, double xy, double yy, double x0, double y0)Sets matrix to be the affine transformation given by xx, yx, xy, yy, x0, y0. The transformation is given by:
<programlisting>x_new = xx x + xy y + x0; y_new = yx x + yy y + y0;
</programlisting>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 |
