How to use Imageset exporter script

How-to

Installation

    $HOME/.gimp-2.8/plug-ins

Usage

1. Make sure that every GUI element is on its own layer, and that layer is cropped.
2. Arrange layers around canvas the way you see fit. Crop the canvas to murder the whitespace.
3. Click File->CEGUI->Export TGA Imageset

The progressbar on the bottom of the Gimp should show that TGA exporter did some work. Go into the directory where you saved your .xcf file and doublecheck that .imageset file and .tga files are there.

Voila!

Code

Yeah, about that. Copy this into file with whichever name you'd like, just make sure it has .py extension.

#!/usr/bin/env python
