How to fix error - TypeError: unsupported operand type(s) for -: 'tuple' and 'int'

Question

I am opening a png file and then filling colour in that png file. My code is working for some png files but not for all.

from PIL import Image, ImageDraw

image = Image.open("H:/baibhav/MPEG7dataset/apple_1.png")
width, height = image.size
center = (int(0.5 * width), int(0.5 * height))
yellow = (255, 255, 0, 255)
ImageDraw.floodfill(image, xy=center, value=yellow)
image.show()

I am expecting a figure as an output but it gives following error:

TypeError: unsupported operand type(s) for -: 'tuple' and 'int'

Answer 1

simply change

image = Image.open("H:/baibhav/MPEG7dataset/apple_1.png")

to

image = Image.open("H:/baibhav/MPEG7dataset/apple_1.png").convert("RGBA")

To know more, please check this . A in RGBA is the alpha parameter. We use the alpha parameter when we want the color to get transparent. In simple words, it controls the opacity in an image.
