Limitations

StillGif doesn't work on target track

In the unregistrered version of Animator you cannot extract separate frames from the target animation track (assembled animation) using the StillGif method. You can retrieve frames from dynamic tracks (source images) only.

Limited amount of dynamic tracks

The Join method accepts not more than two dynamic animation tracks. Therefore, an instance of ShotGraph.GifAnimator object can have two tracks at the most. The number of frames on dynamic tracks is not limited.

Limited amount of frames on the target track

In the moment of creating new animated gif, the amount of frames on the target track should not exceed 5. You can have any amount of frames on the target track, but the Play method will not work on target track containing too big amount of frames. Therefore, your newly created animations will be limited by this amount of frames.
This code shows how you can control that amount of frames in the target animation does not exceeds limit for unregistered version.

Set ani = CreateObject("shotgraph.gifanimator")
ani.Read file1

... Do something ...

ani.Join
' Add this line to control amount of frames in the trial version
if ani.FramesCount > 5 then ani.DeleteFrame -1,5,ani.FramesCount-5
ani.Play new_file
