[jira] [Created] (TIKA-762) EXIF extraction from PNG images
EXIF extraction from PNG images
-------------------------------
Key: TIKA-762
URL: https://issues.apache.org/jira/browse/TIKA-762
Project: Tika
Issue Type: New Feature
Components: parser
Affects Versions: 1.0
Reporter: Nick Burch
Assignee: Nick Burch
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

---------------------------------
It's very easy to replace any parser with another one, simply load your new one after the built in one, and the last to register with a given mimetype will be the one that is used.

-----------------------------------
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
