[reportlab-users] Appengine - Reportlab (Get Photo from Model)

[Martinho Arantes]

I could already make it.
Thanks to user Saxon Druce<http://stackoverflow.com/users/148241/saxon-druce>
 from StackOverflow.com

My code was incomplete. Didn´t read the AppEngine function to resize images,
so as Saxon suggested i changed my code to

             if self.request.get('photo'):
                photo = images.resize(self.request.get('photo '), 40,
40,images.JPEG
)
                user.photo = db.Blob(photo )

*instead of:*

            if self.request.get('photo'):
                photo = images.resize(self.request.get('photo '), 40, 40)
                user.photo = db.Blob(photo )

What Google AppEngine was doing, was converting the image to PNG instead of
JPG.

*Note:* You can see this thread

.
Maybe it´ll help others.
