GIMP Plugin Registry

The Lightbox scripts have been created to make animating 'Frame by frame' easier and more intuitive in Gimp.
It does this by trying to emulate animating traditionally.

The scripts helps organise layers into separate sections allowing Frames, Colour and Backgrounds.
These can all be added and organised from the Animate menu which the script adds.

These layers can then be viewed, composited and exported as an moving animation, .gifs or .tif image sequences for editing.  read more »

This plugin (with the help of the external "gifsicle"-program) produces
GIF-animations with more than 256 colors.

this script adds an "anitools" submenu to the "script-fu" menu with entries useful for creating (optimized) animated GIFs:
create scanlines: paint every other horizontal line in each layer with the current foreground layer. this can decrease the size of the resulting GIF and some people like the look :-)
set image framerate: set the frame rate for all layers in the current image.
set layer framerate: set the frame rate for just the current layer.  read more »
