Stack Layers Vertically

Filters are a great way to make high quality animations for your texture packs. They can provide a wide variety of effects, and can make your textures look truly amazing. They have one downside, however: the output of all animation filters is a layered image, with each frame in its own layer. All the frames must be copied over into another image before they can be used in Minecraft. This process can become extremely time-consuming, especially when you have twenty animations to do, with over three dozen frames each. The process is particularly a hassle when you are making water or lava animations, and the frames must each be tiled as well. That is why I wrote this script, to automate an otherwise time-consuming process. This script takes all the layers of an image and stacks them vertically in a Minecraft-useable filmstrip. It essentially takes this:

and turns it into this:

or this:

I hope this makes the lives of some texture artists a little easier!

OPERATION INSTRUCTIONS:
1. Open GIMP, and open your layered image.
2. Make sure that the layers are in the right order. The first frame of the animation must be at the top, and the last frame at the bottom. If you find that your frames are in the wrong order (i.e. last frame on the top, first frame on the bottom), you can click Layer->Stack->Reverse Layer Order, and it will put your layers in the order they need to be in.
3. Click on Image->Create->Minecraft Animation.
4. If you wish to create a flowing liquid animation, check the "Flowing Liquid" box.
5. The script will create a new image with all the frames of your animation set up in the correct positions for a Minecraft animation.
