Here the most trivial code never written for Gmic
Its basic uses :
1)play as a Magician
2) correct crop errors in Renders
This was already possible with gimp without any need of additional filters ( just by deleting or filling with white the alpha channel)...but is far to be know by most users
It was fun and easy to wrote and anyway may be useful to correct badly cropped render..
no options just click Apply or OK for the result..
.Don't trust the preview (that for unknow reasons will show as transparent or as solid black the area that the filter will resurrect)

#@gimp Resurrect from Transparency : gimp_resurrect, gimp_resurrect
#@gimp : note = note ("This filter may resurrect what erased to full transparency")
gimp_resurrect :
-repeat @# -l[$>]
-split_opacity -keep[-2]
-endl -done

again don't trust the preview
