Method Detail

set

public void set(float xOff,
                float yOff,
                boolean updateScale,
                float scale,
                boolean updateScaleXY,
                float scaleX,
                float scaleY,
                boolean updateAngle,
                float angle)

Set position and optionally scale, anisotropic scale, and/or angle. Where if the corresponding "update" flag is set to false, the field's value will not be changed during a pinch operation. If the value is not being updated *and* the value is not used by the client application, then the value can just be zero. However if the value is not being updated but the value *is* being used by the client application, the value should still be specified and the update flag should be false (e.g. angle of the object being dragged should still be specified even if the program is in "resize" mode rather than "rotate" mode).

set

protected void set(float xOff,
                   float yOff,
                   float scale,
                   float scaleX,
                   float scaleY,
                   float angle)

Set position and optionally scale, anisotropic scale, and/or angle, without changing the "update" flags.
