from PIL import Image

image = Image.open('image.png')

image = image.convert('RGBA')

data = image.getdata()

new_data = []
for item in data:
    # 如果像素点为白色，则设置为透明
    if item[:3] == (255, 255, 255):
        new_data.append((255, 255, 255, 0))  # 设置为透明
    else:
        new_data.append(item)  # 保持原样

image.putdata(new_data)

image.save('transparent_image.png', 'PNG')

pip install Pillow
