6.13.3 Loop
The same as Once , except playback loops to the first frame after the last frame.
When playing forwards, first = start and last = end. When backwards, first = end and last = start.
6.13.4 Bounce
The same as Loop , except the direction automatically changes each time.
Note that the speed parameter is automatically reversed, so that changes in magnitude do not suddenly reverse the direction if
the sign of the speed does not match the direction. i.e. once the first reverse has taken place, only the magnitude of the speed
parameter has any effect unless the speed crosses zero, where the direction of bounce would also change.
6.13.5 First frame
The current first frame is always shown. Although playback is therefore not “dynamic”, the start frame parameter can be altered
in real time to control playback.
6.13.6 Last frame
The current last frame is always shown. Although playback is therefore not “dynamic”, the end frame parameter can be altered
in real time to control playback.
6.13.7 Pause
Playback is paused at whatever the current frame is. This mode can be used in conjunction with other modes, and cues, to achieve
more complex playback effects. For example it allows playback to be paused without setting the speed to zero, so playback can
be restarted with the previous speed. The “resume” cue does not need to have the playback speed programmed.
6.13.8 Next frame
Advances the frame that is displayed, according to the speed parameter (i.e. direction and frame skipping for high speeds still
apply), then automatically pauses. The mode must be changed away (e.g. to Pause ), then back, before this mode can change the
frame again.
Tip
Pause can be used in conjunction with Next Frame (or other modes) to achieve more complex playback effects such as moving
through a slide show.
6.14 Transition
Not implemented yet.
6.15 Mask Opacity
This parameter controls how opaque the mask is. If the opacity is full, the mask has complete control over the transparency of
the layer. As the opacity is reduced, the mask has less effect: black areas that would have been completely transparent becomes
less so, allowing less of the lower layers to show through. As opacity reduces to zero, the mask is effectively switched off.
