from PIL import Image, ImageDraw, ImageFont

def add_num(img):
    draw = ImageDraw.Draw(img)
    myfont = ImageFont.truetype('C:/windows/fonts/Arial.ttf', size=40)
    fillcolor = "#ff0000"
    width, height = img.size
    draw.text((width-40, 0), '99', font=myfont, fill=fillcolor)
    img.save('result.jpg','jpeg')

    return 0
if __name__ == '__main__':
    image = Image.open('image.jpg')
    add_num(image)

运行时提示错误：

python 版本:3.4.3，在win10上运行，vs2015
我如果调用PIL.Image 的show()方法时，会提示
