The Gimp 
Logiciel de traitement d'image. Le nom signifie the GNU Image Manipulation Program (GIMPprononcer "Guimp" et non "jimp").
Étape 1 - Ouvrez le logiciel The Gimp, chargez l'image et détourez la forme
Ici, le fond est blanc,le détourage se fait avec l'outil de sélection par couleur.
Je copie le fond blanc.
Étape 2 - J'insère un nouveau calque sur le quel je colle le détourage
Pour insérer un calque je cliques sur "Calque" -> "nouveau calque".
je colle le détourage sur le nouveau calque.
Étape 3 - Remplir le détourage de noir
Et je supprime le premier calque pour finir.
Étape 4 - Changer le mode de l'image pour le mode couleur indexé
Choisir 2 couleurs
Étape 5 - Ajustement de la taille
Cliquer sur "Edition" -> "Echelle et taille de l'image"
Réduisez la résolution, et mettez la taille à la dimension voulue (ici l'écran oled faisant 64 pixel de haut, c'est 64 px qu'on choisis).
Mettez à l'échelle et hop votre réduit. Agrandissez la visualisation en appuyant sur la touche "+".
Étape 6 - retpouchez les pixels un à un
avec l'outil crayon, en réglant le diamètre à 1 pixel (C'est aussi de cette manière que vous pouvez faire des dessins libres).
Étape 7 - Exportez en xbm
Cliquez sur "Fichier" -> "Exporter sous"
Choisir le format d'export voulu : .xbm
Vérifier le fichier exporter en l'ouvrant avec un éditeur de texte.
Avec cette base, vous pouvez réaliser un Badge avec un écran Oled par exemple.
