Source Editing - Scroll (A->B->A)
When you select Scroll (A->B->A) from the Creation method list of the Source Image tab, you can have the animation scroll from one part to another of an image, then scroll back to the original place.
This scrolling effect is shown in the following figure where you scroll from A to B, then return to A.
Using the above figure as an example, here's how to set the animation to scroll from A to B then back to A.
Procedure
1. Select Scroll (A->B->A) from the Creation method list.
2. Click the Start button.
=>A cutting frame is shown in the image area.( The white rectangular frame in the figure below)
3. Select the start point for scrolling by dragging and resizing the cutting frame as you like.
4. Click the End button.
5. Select the end point of the scrolling by dragging and resizing the cutting frame as you like.(Figure below)
6. Select the number of frames to import. The higher the number of frames, the smoother the animation operates.
The standard number of frames is 30.
By changing the value of Number of Frames to Import in the range from 1 to 90, you can increase or decrease the number of frames.
The maximum number of frames for a series of animation images is 90.
7. Click the Execute button.
With this procedure you create an image that scrolls from position A toward position B and then back to position A.
When another panel animation is already set in the preview section, a dialog box opens, asking for the insertion position of the new panel in relation to the currently displayed frame.=>For details, go here.

The result (current total of frames) imported by the current scrolling operation is displayed In the right-side frame of the preview section.
8. Specify the color tone in the right-side preview section.(Large Arrow)
Set the tone by combining the colors red, green and blue, each of which has four possible tones. The farther the slider moves toward the right, the stronger each color tone becomes.
You can verify the adjusted color tone in the preview panel.
9. Trying out previewing.

Click the Start Play button in the right-side preview section.
Check that the image scrolls properly from position A toward B then back to A.

When repeat play () is specified with A->B->A the animation appears to stop for a moment as the A->B->A cycle is repeated. This happens because the start point image and the first frame to start repeat play are the same frame, so by repeating the same frame at this point, the animation appears to stop. To avoid this illusion, follow this procedure:
1. Select the last frame in the preview section. (Move the frame slider to the right end.)
2. When you are at this position, click the Delete button.
By removing the last frame of the panel animation, you will now get smooth repeat play.
