我就废话不多说了，直接上代码吧！
from PIL import Image
# 通道转换
def change_image_channels(image, image_path):
# 4通道转3通道
if image.mode == 'RGBA':
r, g, b, a = image.split()
image = Image.merge("RGB", (r, g, b))
image.save(image_path)
# 1 通道转3通道
elif image.mode != 'RGB':
image = image.convert("RGB")
os.remove(image_path)
image.save(image_path)
return image
# 图片压缩
def image_compression(image):
w, h = image.size
print(w, h)
image.thumbnail((int(w / 1.1), int(h / 1.1)))
image.save("./car.png")
return image
if __name__ == "__main__":
image = Image.open("./timg.png")
new_image = process_image_channels(image, "./time.png")
print(new_image.mode)
