You have to call execute_transform with parse_metadata=True.
App Engine will document the feature soon. I understand you are very much
interested in trying it out, so you can just use the docstring from the SDK
api/images/__init__.py to understand what is the return value of
Got it. Now when I execute:
orgImg = images.Image(image_data)
orgImg.rotate(0)
orgImg.execute_transforms(parse_source_metadata=True)
self.response.out.write(orgImg.get_original_metadata())
I do get a larger subset of EXIF data from my app when it's running on GAE
server!
Martin,
I don't know
I have just checked with an image with GPS info and I correctly got back the
EXIF. The lat/long info are in the dictionary with keys GPSLatitude
and GPSLongitude.
If this doesn't work for you, please send a link to the image in question
and I can look into. In general it should work with images
Gyuri,
You are absolutely correct. I made a bad assumption based on Martin's
statement about *still have not successfully lat/long exif data out of JPG's
*and my own initial results. The production photos I was looking at the
results from *get_original_metadata* calls ironically enough
Any updates on this? With App Engine 1.5.3
Pre-releasehttps://groups.google.com/forum/#!topic/google-appengine/gi8F8lWzRJUbeing
announced, I was hoping someone would acknowledge
*get_original_metadata* was broken and was being addressed in the next
release.

Hi Ed,
I've been discussing this with Jose, and have made a little progress but still
have not successfully lat/long exif data out of JPG's.
He told me that in order to get a value other than None, execute_transforms()
must be called on the image object. So, if you have no transformations, you
Thanks for the pointer Martin. By adding the lines of code before calling *
get_original_metadata*:
orgImg.rotate(0)
orgImg.execute_transforms()
orgImg.get_original_metadata()
I am able to get the following data EXIF data now:
{u'ImageLength': 480, u'ImageWidth': 640}
but that really doesn't
Hi Ed,
I looked at the source and it is just an instance method of the images.Image
class, called with no parameters, i.e. image.get_original_metadata()
I'm stilling getting None from the method, I have tried it both by
instantiating an Image from a blob_key and directly with image data, in
Thanks for confirming this. I was calling it the same way (similar to the
*histogram
*method) but since I wasn't seeing any data (it was also returning *None*),
I thought I was not calling *get_original_metadata* properly.
I was using some of the sample photos found over on
