Page 251 highlights

ADOBE FIREWORKS CS3 246 User Guide No Onion Skinning turns off onion skinning and displays only the contents of the current frame. Show Next Frame displays the contents of the current frame and the next frame. Before and After displays the contents of the current and adjacent frames. Show All Frames displays the contents of all frames. Custom sets a custom number of frames and controls the opacity of onion skinning. Multi-Frame Editing lets you select and edit all visible objects. Deselect this option to select and edit only objects in the current frame. Tweening Tweening is a traditional animation term that describes the process in which a lead animator draws only the keyframes (frames containing major changes) while assistants draw the frames in between. In Fireworks, tweening blends two or more instances of the same symbol, creating interim instances with interpolated attributes. Tweening is a manual process useful for more sophisticated movement of an object across the canvas and for objects whose Live Filters change in each frame of the animation. For example, you can tween an object so that it seems to move along a linear path. To tween instances: 1 Select two or more instances of the same graphic symbol on the canvas. Do not select instances of different symbols. 2 Select Modify > Symbol > Tween Instances. 3 Enter the number of tween steps to be inserted between the original pair in the Tween Instances dialog box. 4 To distribute the tweened objects to separate frames, select Distribute to Frames and click OK. If you choose not to distribute the objects to separate frames, you can do it later by selecting all instances and clicking the Distribute to Frames button in the Frames panel. Note: In most cases, using animation symbols is preferable to tweening. For more information, see "Working with animation symbols" on page 239. Previewing an animation You can preview an animation while you are working on it to check its progress. You can also preview an animation after optimization to see how it will look in a web browser.

Tweening
Tweening
is a traditional animation term that describes the process in which a lead animator draws only the
keyframes (frames containing major changes) while assistants draw the frames in between.
In Fireworks, tweening blends two or more instances of the same symbol, creating interim instances with interpo-
lated attributes. Tweening is a manual process useful for more sophisticated movement of an object across the canvas
and for objects whose Live Filters change in each frame of the animation.
For example, you can tween an object so that it seems to move along a linear path.
To tween instances:
1
Select two or more instances of the same graphic symbol on the canvas. Do not select instances of different
symbols.
2
Select Modify > Symbol > Tween Instances.
3
Enter the number of tween steps to be inserted between the original pair in the Tween Instances dialog box.
4
To distribute the tweened objects to separate frames, select Distribute to Frames and click OK.
If you choose not to distribute the objects to separate frames, you can do it later by selecting all instances and
clicking the Distribute to Frames button in the Frames panel.
Note:
In most cases, using animation symbols is preferable to tweening. For more information, see “Working with
animation symbols” on page 239.
