GIMP Spritesheet Exporter plugin (Python-fu)

Export multiple layers from GIMP to a spritesheet (png+xml).

Howto:

• Only visible layers will be exported
• Layers with name in brackets are used as a background for every sprite
• File > Export Spritesheet
• Select output directory
• Spritesheet .png and .xml metadata will be exported (filename same as GIMP file).
• All sprites need to be the same size
• Sprites will be ordered to form a square, roughly

Example input:

Example output:

<TextureAtlas imagePath='spritesheet.png'>
  <SubTexture name='shifty' x='0' y='0' width='32' height='32'/>
  <SubTexture name='hey' x='32' y='0' width='32' height='32'/>
  <SubTexture name='suspicious' x='64' y='0' width='32' height='32'/>
  <SubTexture name='scared' x='0' y='32' width='32' height='32'/>
  <SubTexture name='excited' x='32' y='32' width='32' height='32'/>
  <SubTexture name='wow' x='64' y='32' width='32' height='32'/>
  <SubTexture name='normal' x='0' y='64' width='32' height='32'/>
</TextureAtlas>
