ofn-erase-background

[Ofnuts]

A quick script to automate the background erasure when the background is uniform.

To use:

• Make a selection on the background using the fuzzy selector with a threshold big enough to include small irregularities
  
• Use Layer>Erase background
  

The script uses the now-classic color-to-alpha-on-grown-selection with a couple of enhancements:

• Most of the background is completely deleted and is guaranteed to be totally transparent (thanks Blighty)
  
• The color used for color-to-alpha is deduced from the erase background color, and so doesn't ned to be specified.
