I'm having some trouble knowing if an image has been horizontally or vertically flipped or not. Returning the properties of a flipped photo doesn't seem to contain any information about the applied transformation, other than to mistakenly claim a "rotation" of 180�. However, this is clearly not what has happened to the photo, for it you specifically apply a 180� rotation, the result is visually different.

Is there a property I can check on an picture frame to determine if horizontal or vertical flip has been applied to it's contents? Perhaps I'm just blind to something that's sitting right in front of my face?

Thanks,
Christopher
