Description

Créer le négatif d’une image. Pour cela, on change chaque couleur par son complémentaire.

Contributor guide

Research direction
Understand the image data structure (e.g., pixel format, color channels). For each pixel, compute the negative by subtracting each color component from its maximum value (e.g., 255 for 8 bit channels). Implement a loop over all pixels and apply the transformation.
