Setting the frame disposal method
The frame disposal method specifies whether to discard the current frame before
displaying the next frame. You select a disposal method when working with animations
that include background transparency in order to specify whether the current frame will
be visible through the transparent areas of the next frame.
Illustration of frame disposal methods:
A.
Frame with background transparency with Restore to Background option
B.
Frame with
background transparency with Do Not Dispose option
The Disposal Method icon indicates whether the frame is set to Do Not Dispose
or
Restore to Background . (No icon appears when disposal method is set to Automatic.)
To choose a disposal method:
1
Select a frame or frames for which you want to choose a disposal method.
2
Right-click (Windows) or Ctrl-click (Mac OS) the frame thumbnail to view the Disposal
Method context menu.
3
Choose a disposal method:
•
Automatic to determine a disposal method for the current frame automatically,
discarding the current frame if the next frame contains layer transparency. For most
animations, the Automatic option yields the desired results and is, therefore, the
default option.
Note:
Choose the Automatic disposal option when using the Redundant Pixel Removal
optimization option, to enable ImageReady to preserve frames that include transparency.
•
Do Not Dispose to preserve the current frame as the next frame is added to the display.
The current frame (and preceding frames) may show through transparent areas of the
next frame. To accurately preview an animation using the Do Not Dispose option,
preview the animation in a browser.
•
Restore to Background to discard the current frame from the display before the next
frame is displayed. Only a single frame is displayed at any time (and the current frame
will not appear through the transparent areas of the next frame).
