Desde que lançaram o Gimp v3, eu meio que fiquei órfão do plugin "national geographics", que dá um tchans legal nas fotos.
Mas hoje eu resolvi apostar na... AI. Se ela faz algumas tarefas com pés nas costas, porque não arriscar converter o plugin pra Gimp V3?
E foi o que fiz.
Aqui está uma foto normal, sem o plugin.
e agora com o plugin aplicado:
Dá ou não dá aquele talento na foto? Claro que dá.
O script convertido segue abaixo:
#!/usr/bin/env gimp-script-fu-interpreter-3.0
;
; GIMP 3 port of elsamuko National Geographic (2008).
; Reconstructed layer pipeline. Requires testing against the target GIMP 3 build.

Eu copiei esse conteúdo pro arquivo ~/.config/GIMP/3.2/scripts/elsamuko-national-geographic-gimp3.scm e iniciei o Gimp.
O original é daqui: https://github.com/elsamuko/gimp-elsamuko/blob/master/scripts/elsamuko-national-geographic.scm
Como é slop generated, eu não copiei esse plugin pra nenhum lugar, nenhum repositório. O próprio codeberg proíbe uso de slop generated code. Então fica aqui pra quem quiser.
