Henry Qin updated IMAGING-336:
------------------------------
Priority: Minor (was: Major)
> Allow editing GIF metadata without re-encoding
> ----------------------------------------------
>
> Key: IMAGING-336
> URL: https://issues.apache.org/jira/browse/IMAGING-336
> Project: Commons Imaging
> Issue Type: Improvement
> Components: Format: GIF
> Reporter: Henry Qin
> Priority: Minor
>
> Today, if we try to remove or change metadata in GIF images and then convert
> the GIF back into a bytes, it causes a re-encoding of the entire GIF, which
> can increase its file size.
> I think it would helpful if there was a way to edit or remove metadata on a
> GIF without reencoding the other blocks. This should guarantee that GIFs
> cannot grow after removing metadata.
> If the maintainers of this project feel like this is a worthwhile improvement
> and are willing to do a new minor release when it's done, I'm interested in
> helping to bring this functionality into the library.
