These two functions control the animation state. You can also use the animate
property (see below).
Call update()
after adjusting properties of the wave.
Use this function to set the linestyle used for the curve. The object obj
can have properties thickness
, color
, alpha
, and (instead of color
) wavelength
. If wavelength
is a number between 400 and 700 the color of the curve will be that of the corresponding wavelength of light (in nm).
wavelength
is specified in pixels.
amplitude
is specified in pixels.
width
determines the horizontal extent of the sinusoid component, in pixels.
phase
is given as a number between 0 and 1.
This property reflects and controls the animation state: true
if animating and false
if paused. Note also the pauseAnimation()
and startAnimation()
functions (see above).
