# Animation NPS Image Editor supports basic frame animation, including animated GIFs. ## Enabling animation Use the Image -> Enable Animation command to turn on animation for your image. This will give you access to animation options and will allow you to save the resulting file as an animated GIF. If you open an existing animated GIF, this will be done automatically. ## Editing frames Use the Layer Properties dialog to edit each frame's delay and disposal method. These define how the animation is performed. ### Frame delay Specifies the amount of time, in milliseconds, that the current frame is displayed. Once the delay runs out, the next frame will be displayed. Note that different browsers might interpret this value differently and very small values (i.e. below 60 ms) might appear as much longer delays. ### Frame disposal method Specifies what happens to the current frame when the next frame is displayed. Note that the exact behavior also depends on the transparent regions within the frame's image data; frame disposal is irrelevant for a fully opaque frame that fully covers the previous one. #### Default Depending on the browser, the entire frame will be replaced by the next frame, or will act the same as Combine. #### Combine The next frame will overlay the current frame. Any opaque pixels will cover the frame beneath it and any transparent pixels will show the previous color. #### Restore Background The background layer replaces the current frame, then the next frame will combine with it. #### Restore Previous Similar to Restore Background, but replaces the current frame with the previous frame. This behavior also depends on the browser implementation. ## Previewing animation As of NPS Image Editor 4.2, there is no way to preview the animation within the editor. You will need to save as an animated GIF and view it in a browser.
