我在这个问题上看到了多个问题，但没能找到问题的答案。基本上，我只想在图像上画一条线，从python中的外部文件中获取坐标。我的代码是：import Image, ImageDraw

import sys

import csv

im = Image.open("screen.png")

draw = ImageDraw.Draw(im)

with open("outputfile.txt") as file:

reader = csv.reader(file, delimiter=' ')

for row in reader:

if row[0] == 'H':

print "Horizontal line"

endx = row[2]

endy = int(row[3])+int(row[1])

elif row[0] == 'V':

print "Vertical line"

endx = row[2]+row[1]

endy = row[3]

x = row[2]

y = row[3]

draw.line((x,y, endx,endy), fill = 1)

im.show()

除了台词，一切都正常：

^{pr2}$

我看到以下错误：File "dummy_test.py", line 21, in

draw.line((x,y, endx,endy), fill = 1)

File "/Library/Python/2.7/site-packages/PIL-1.1.7-py2.7-macosx-10.10- intel.egg/ImageDraw.py", line 200, in line

self.draw.draw_lines(xy, ink, width)

SystemError: new style getargs format but argument is not a tuple

如果我硬编码这些值，我看不出问题。问题只发生在上述情况下。有人能指出问题吗？在
