PIL Image / python-resize-image AttributeError

[sallyjc81]

Hi, I am getting an Attribute Error when using the PIL mage module. Not sure what the cause is as the no attribute of 'upper' is not written in the code, and when searching for similar errors, the missing attribute seems to be written in the code.

for file in glob.glob("*.png"):
  img = Image.open(file)
  rec = resizeimage.resize_crop(img, [200, 100])
  filename = "rec_"+ file 
  img.save(output + filename, rec)

Error:
AttributeError                            Traceback (most recent call last)
<ipython-input-23-f08ed3820260> in <module>()
      3   rec = resizeimage.resize_crop(img, [200, 100])
      4   filename = "rec_"+ file
----> 5   img.save(output + filename, rec)

/usr/local/lib/python3.6/dist-packages/PIL/Image.py in save(self, fp, format, **params)
   2084                 raise ValueError("unknown file extension: {}".format(ext))
   2085 
-> 2086         if format.upper() not in SAVE:
   2087             init()
   2088         if save_all:

AttributeError: 'Image' object has no attribute 'upper'

What is the cause and solution to this error? Would be much appreciated.

rec parameter should specify the format of an image, e.g. "png", "jpeg" etc. In your case, you passed an Image-instance (rec is an Image instance). Try, e.g. img.save(output+filename, 'png')
