Getting error on resize img using pillow and python3.8-CodePudding

Here is my code.

from PIL import Image
imgwidth = 800
img = Image.open('img/2.jpeg')
concat = (imgwidth/img.size[0])
height = float(img.size[1])*float(concat)
img = img.resize((imgwidth,height), Image.ANTIALIAS)
img.save('output.jpg')

I found this example from a blog. I have run this code and got the bellow error, I am new in python and not understand the actual problem.

File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/PIL/Image.py", line 1929, in resize
    return self._new(self.im.resize(size, resample, box))
TypeError: integer argument expected, got float

CodePudding user response：

as img.resize() function expect integer value for height, so please make sure height should be an integer type. Update your code with the below code, I hope it should be working for you.

from PIL import Image
imgwidth = 800
img = Image.open('img/2.jpeg')
concat = float(imgwidth/float(img.size[0]))
height = int((float(img.size[1])*float(concat)))
img = img.resize((imgwidth,height), Image.ANTIALIAS)
img.save('output.jpg')
