[Resolvido] Python OOP

Recommended Posts

Boas,

Tou com uma dúvida que não tou a perceber ainda a estrutura de OOP.

A minha dúvida:

class App:
  def __init__(self):
    pass

  def openImage(self, path):
    self.path = path
    img = cv2.imread(self.path)
  
  def convertGray(self):
    result_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

## Devolve o erro que não tem nenhuma var img definida quando  var img está declarada no metodo acima, como passo o valor da var img do metodo openImage para o metodo convertGray ###
