La méthode CanvasRenderingContext2D.fill() de l'API Canvas 2D remplit le chemin courant ou donné avec la couleur de fond en cours, en utilisant la règle de remplissage extérieur/intérieur non nul ou la règle de remplissage pair/impair.
void ctx.fill([fillRule]); void ctx.fill(path[, fillRule]);
fillRule"nonzero": La règle de remplissage extérieur/intérieur non nul, qui est la règle par défaut."evenodd": La règle de remplissage pair/impair.pathfillCeci est un simple snippet de code qui utilise la méthode fill pour remplir un chemin.
