* Optional arguments:
*
* * @scale: scale by this factor
* * @angle: rotate by this many degrees anticlockwise
* * @interpolate: interpolate pixels with this
* * @idx: input horizontal offset
* * @idy: input vertical offset
* * @odx: output horizontal offset
* * @ody: output vertical offset
* * @scale: %gdouble, scale by this factor
* * @angle: %gdouble, rotate by this many degrees clockwise

* This operator calls vips_affine() for you, calculating the matrix for the
* affine transform from @scale and @angle. Other parameters are passed on to
