Onion skinning
Normally, Flash displays one frame of the animation sequence at a time on the Stage. To help you
position and edit a frame-by-frame animation, you can view two or more frames on the Stage at
once. The frame under the playhead appears in full color, while surrounding frames are dimmed,
making it appear as if each frame were drawn on a sheet of translucent onion-skin paper and the
sheets were stacked on top of each other. Dimmed frames cannot be edited.
To simultaneously see several frames of an animation on the Stage:
•
Click the Onion Skin button. All frames between the Start Onion Skin and End Onion Skin
markers (in the Timeline header) are superimposed as one frame in the Document window.
To control onion skinning display, do any of the following:
•
To display onion skinned frames as outlines, click the Onion Skin Outlines button.
•
To change the position of either onion skin marker, drag its pointer to a new location.
(Normally, the onion skin markers move in conjunction with the current frame pointer.)
•
To enable editing of all frames between onion skin markers, click the Edit Multiple Frames
button. Usually onion skinning lets you edit only the current frame. However, you can display
the contents of each frame between the onion skin markers normally, and make each available
for editing, regardless of which is the current frame.
Note: Locked layers (those with a padlock icon) aren't displayed when onion skinning is turned
on. To avoid a multitude of confusing images, you can lock or hide the layers you don't want
onion skinned.
To change the display of onion skin markers:
•
Click the Modify Onion Markers button and select an item from the menu:
Always Show Markers
onion skinning is on.
Anchor Onion
Normally, the Onion Skin range is relative to the current frame pointer and the Onion Skin
markers. By anchoring the Onion Skin markers, you prevent them from moving with the
current frame pointer.
Onion 2
displays two frames on either side of the current frame.
Onion 5
displays five frames on either side of the current frame.
Onion All
displays all frames on either side of the current frame.
