python如何调整图片大小,在python中调整图像大小

I have an image of size (288, 352). I want to resize it to (160, 240).

I tried the following code:

im = imread('abc.png')

img = im.resize((160, 240), Image.ANTIALIAS)

But it gives an error TypeError: an integer is required

Please tell me the best way to do it.

解决方案

matplotlib.pyplot.imread (or scipy.ndimage.imread) returns a NumPy array, not a PIL Image.

Instead try:

In [25]: import Image

In [26]: img = Image.open(FILENAME)

In [32]: img.size

Out[32]: (250, 250)

In [27]: img = img.resize((160, 240), Image.ANTIALIAS)

In [28]: img.size

Out[28]: (160, 240)
