When editing Animated GIF files, you can use the Global Settings command to specify several general options that affect how your animation will play. (VisualNEO for Windows Cartoon files do not have global settings.)
The Display Size of the animation can be adjusted using the Width and Height fields. The width and height entered here should not be less than the size of the largest frame in the file. Use the Calculate check box to automatically set the target size to that of the largest frame.
Select the Play Continuously check box to cycle the animation's frames repeatedly during playback. When the animation reaches the last frame it will automatically start again at the beginning.
Some programs that play Animated GIFs may ignore these settings.
