Select animation settings

  1. Click the Animation tab.

    • To display a single state, select a state from the list on the left side of the dialog box. You can also use the state controls in the lower-right area of the dialog box.

    • To play the animation, click the Play/Stop control in the lower right area of the dialog box.

  2. To specify the state disposal method, select a state from the list, click the trash can icon, and select one of the following options:

    Unspecified
    Determines a disposal method for the current state automatically, discarding the current state if the next state contains layer transparency. For most animations, this default, automatic option yields the best visual results and smallest file sizes.

    None
    Preserves the current state as the next state is added to the display. The current state (and preceding states) may show through transparent areas of the next state. Use a browser to see an accurate preview of an animation using this option.

    Restore to Background
    Discards the current state and temporarily replaces it with the background of the web page. Only one state appears at a time. Choose this option if animated objects move above a transparent background.

    Restore to Previous
    Discards the current state and temporarily replaces it with the previous state. Choose this option if animated objects move above an opaque background.

  3. To set the state delay, select a state from the list and enter the delay time in hundredths of a second in the State Delay box.

  4. To set the animation to play repeatedly, click the Looping button and select the number of repetitions from the pop-up menu.

  5. To crop each state so that only the image area that differs between states is output, select Crop Each State. This option reduces file size.

  6. To output only pixels that change between states, select Save Differences Between States. This option reduces file size.
