Viewing Animations; Optimizing Animations - Adobe PHOTOSHOP 6.0 Manual

To flatten frames into layers:
In the Animation palette, choose Flatten Frames
into Layers from the palette menu.

Viewing animations

Viewing an animation lets you preview the frames
in timed sequence. You can preview an animation
in ImageReady or in a Web browser.
To view an animation in ImageReady:
Click the Play button ( ) in the Animation
1
palette. The animation is displayed in the
document window. The animation repeats
indefinitely unless you specified another repeat
value in the Play Options dialog box.
(See "Specifying looping" on page 306.)
2 To stop the animation, click the Stop
button ( ).
3 To rewind the animation, click the Rewind
button ( ).
To preview an animation in a browser:
1 Click the Preview in Default Browser tool (
( ) in the toolbox, or choose File > Preview In
and select a browser from the submenu.
2 Use the browser's Stop and Reload commands
to stop or replay the animation.

Optimizing animations

You can apply optimization settings to animated
images just as you do to nonanimated images.
(See "Optimizing images" on page 320.)
You should always optimize an animation in
GIF format because GIF is the only format in
ImageReady that supports the display of animated
images on the Web.
Note: While you can optimize an image that
includes animation in JPEG or PNG format,
these formats do not support animation.
The resulting Web page will display only the first
frame of the animation.
In addition to the standard optimization options
for GIF format, you can optimize frames to
include only areas that change from frame to
frame. (This greatly reduces the file size of the
animated GIF.) ImageReady also applies a special
dithering technique to animations to ensure that
dither patterns are consistent across all frames and
to prevent flickering during playback. Due to these
additional optimization functions, ImageReady
may require more time to optimize an animated
GIF than to optimize a standard GIF.
