When using the Draw appearance it seems the orientation of the image is not set

Question

When using the draw appearance my images are not getting a orientation tag it seems.  I have a script that reads the photo orientation and it is stopping on these images from 123.

if hasattr(image, '_getexif'):
      orientation = image._getexif().get(274, 1) # 274 = Orientation
else:
      orientation = 1

in fill_page_with_image
orientation = image._getexif().get(274, 1) # 274 = Orientation
AttributeError: 'NoneType' object has no attribute 'get'

Anyone seen this before?

Thanks

Code looks fine. I would suspect that the file formats between the drawings & pictures is different, and therefore returns NoneType. What format are the drawings in?

edit: looks like the ._getexif() method only supports jpg & tiff

I see that you added some conditional statements to the lines that were throwing the error. Use 'try' instead of if statements. That way, your script can handle errors w/o failing.

It worked on our entire dir which is about 45,000 photos.  The drawings from 123 were the only photos that had an issue.  Regular 123 photos were fine.

Here is the code.  It stops on the line I posted.  Seems like an exif issue?

if hasattr(image, '_getexif'):
      orientation = image._getexif().get(274, 1) # 274 = Orientation
else:
      orientation = 1

in fill_page_with_image
orientation = image._getexif().get(274, 1) # 274 = Orientation
AttributeError: 'NoneType' object has no attribute 'get'

thanks

Does it work with all pictures, or just a few? Can you post the rest of your code?
