我正在尝试使用python为动画图像添加水印，但是我收到了一条错误消息：
coercing to Unicode: need string or buffer, Image found
def water(img, watermark):
mark = Image.open(watermark)
try:
im = Image.open(img)
if im.mode != 'RGBA':
im = im.convert('RGBA')
layer = Image.new('RGBA', im.size, (0,0,0,0))
position = (im.size[0]-mark.size[0], im.size[1]-mark.size[1])
layer.paste(mark, position)
frames = i2g.readGif(im, False)
frames_out = []
for frame in frames:
frames_out.append(Image.composite(layer, frame, layer))
writeGif('out.gif', frames_out, duration=0.5, dither=0)
except Exception, (msg):
print msg
def test():
water(sys.argv[1], "water.png")
文件：
This is image that i want to put my watermark - neo.gif
My watermark - water.png
error during executing
如何修复该错误？我无法在gif图像上添加水印 以下是my previous post
