Merge-anim is a script that I have written in August
1998 and updated recently for the current version of the GIMP. It
can be used to merge the background or top layer of an image with all
other layers, while applying some optional effects such as
translation, varying transparency, ... This is useful if you want to
create an animation quickly or if you want to add some new elements
to an existing animation. You will find it in the menu
Script-Fu / Animators / Merge layer with others...
The diagram on the right shows how the
script can be used: an animation with 5 frames is merged with a
background layer. The result is a new animation in which all frames
have the same background. More complex effects (scrolling, fading)
can be obtained by varying the offset or opacity of the layers during
Like all other scripts,
merge-anim does nothing more
than automating some tasks that you could also do by hand, but it is
very useful because you can save a lot of time by using it. For more
complex animations you probably need something like the GAP plug-ins
Video menu), but
simple and fast and it is sufficient most of the time.
The following pages contain some examples of what you can do with
merge-anim script... This is a kind of
mini-tutorial. The first example is very simple. The "burning
arrow" example shows how the script can be used twice on the same
animation to create some interesting effects.
The animation at the top of this page was created by using this
script on an image created with
Xtns / Script-Fu / Logos / Cool
Metal and an animation created with
Script-Fu / Animators
/ Waves. It should not be hard for you to find out how I did
it, after looking at the examples above.
The new version of the script allows you to merge an animation with
a layer from another image. It is also possible to undo your changes
if you did not run this script with the correct options. You can see
some of the options on the screenshot of the parameters dialog.
To install the script, save it in your personal directory
[back to my GIMP page]
~/.gimp-1.2/scripts/ or (as root) in the common directory
