Method Detail

setAngle

public void setAngle(float angle)

Set the angle of twirl in radians. 0 means no distortion.

Parameters:

angle - the angle of twirl. This is the angle by which pixels at the nearest edge of the image will move.

getAngle

public float getAngle()

Get the angle of twist.

Returns:

the angle in radians.

setCentreX

public void setCentreX(float centreX)
