Fabian Lange commented on TIKA-762:
-----------------------------------

Hi, I noticed that ImageMetadataExtractor has Classes from the Metadata 
Extractor Lib on its public API.
I think this should be changed, as it does not allow replacing this library 
with one that can parse additional formats.
Or you add a second ImageMetadataExtractor which works with a different lib.
What d you think? In the second case one could implement some metadatareading 
using javax.imageio
                
> EXIF extraction from PNG images

> The PNG parser doesn't currently extract EXIF information. Only core image 
> properties are currently extracted
> This means that for a PNG produced by an iPad (as an example), we miss out on 
> some of the available metadata
