Figure 15.61. The GIF Export dialog

	Warning
The GIF file format does not support some basic image properties such as partial transparency and print resolution. GIMP also only supports exporting with a maximum of 256 colors. For best results, set your image to indexed mode when you intend to export to GIF. If you care for these properties, use a different file format like PNG.

GIF Options

Interlace: Checking interlace allows an image on a web page to be progressively displayed as it is downloaded. Progressive image display is useful with slow connection speeds, because you can stop an image that is of no interest; interlace is of less use today with our faster connection speeds.
Save comment: GIF comments support only 7-bit ASCII characters. If you use a character outside the 7-bit ASCII set, GIMP will export the image without a comment, and then inform you that the comment was not saved.

Animated GIF Options

When working on an animation, the name of the layer can be used to specify certain parameters. For more details see exporting animations.

Note: exporting a GIF animation does not support layer groups.

As animation

When this option is checked, the image will be exported as an animation. Note that this option will be disabled (and the animation options will not be visible) if the image has only one layer.

Number of repeats

You can set how many times the animation will repeat before it stops. This value is ignored if Loop forever is checked.

Loop forever

When this option is checked, the animation will play repeatedly until you stop it.

Delay between frames when unspecified

You can set the delay, in milliseconds, between frames if it has not been set before. In this case, you can modify every delay in the Layers dialog. Note that some operating systems and applications may override with a lower frame rate due to computer speed, performance, or other technical limitations.

Frame disposal when unspecified

If this has not been set before, you can set how frames will be superimposed. You can select among three options:

I don't care: you can use this option if all your layers are opaque. Layers will overwrite what is beneath.
Cumulative layers (combine): previous frames will not be deleted when a new one is displayed.
One frame per layer (replace): previous frames will be deleted before displaying a new frame.

Use delay entered above for all frames

The Delay between frames when unspecified value will be used for all frames.

Use disposal entered above for all frames

The Frame disposal when unspecified value will be used for all frames.
