Créer des bords noirs sur fond blanc (Create black borders on a white background) - Ethan Burke - 05-12-2025
Bonjour,
[Pour commencer je pose ma question en Français, mais peut-être qu'il aurait fallu que j'utilise l'Anglais ?]
Ma question : je voudrais simplement retrouver la fonction "Photocopie" de Photoshop, j'ai essayé avec "Filtres" / "Détection de bord" / "Bord" , mais ça me crée une image à fond noir et lignes blanches, alors que je recherche une image à fond blanc et lignes noires, comme une photocopie noir et blanc...
Merci d'avance !
Yes, you should post in English, there are good web translation sites around. - rich

[To begin with, I'm asking my question in French, but perhaps I should have used English].
My question: I'd just like to get back to Photoshop's “Photocopy” function, I've tried with “Filters” / “Edge detection” / “Edge” , but it creates an image with a black background and white lines, whereas I'm looking for an image with a white background and black lines, like a black and white photocopy...
Thanks in advance!

First: Using GEGL filters for this particular edit: enable the Merge filter option, (bottom of GEGL dialogues) otherwise you get strange results.

Using the Edge filter
Apply the filter
Desaturate the image: Colors -> Desaturate -> Desarurate
Invert the image: Colors -> Invert
