我有程序在这里我在堆栈溢出时遇到了一个问题。它应该调整图像的对比度,但是我得到以下错误:
Traceback (most recent call last):
File "<string>", line 420, in run_nodebug
File "<module1>", line 20, in <module>
File "<module1>", line 16, in change_contrast
File "C:\EduPython\App\lib\site-packages\PIL\Image.py", line 1512, in putpixel
return self.im.putpixel(xy, value)
TypeError: integer argument expected, got float
帖子已经很老了所以我不认为写这篇文章的人会看到我的请求,所以我在这里发帖。 这是代码:
from PIL import Image
def change_contrast(img, level):
def truncate(v):
return 0 if v < 0 else 255 if v > 255 else v
img = Image.open("C:\\Users\\omar\\Desktop\\Site\\Images\\obama.png")
img.load()
factor = (259 * (level+255)) / (255 * (259-level))
for x in range(img.size[0]):
for y in range(img.size[1]):
color = img.getpixel((x, y))
new_color = tuple(truncate(factor * (c-128) + 128) for c in color)
img.putpixel((x, y), new_color)
return img
result = change_contrast('test_image1.jpg', 128)
result.save('test_image1_output.jpg')
print('done')
答案 0 :(得分:1)
嗯,什么&#39; truncate
?
尝试说出您int
所在的truncate
。
