Bruno P. Kinoshita updated IMAGING-237:
---------------------------------------
Assignee: (was: Bruno P. Kinoshita)
> The PNG parser must inform the user if the compression method is not supported
> ------------------------------------------------------------------------------
>
> Key: IMAGING-237
> URL: https://issues.apache.org/jira/browse/IMAGING-237
> Project: Commons Imaging
> Issue Type: Improvement
> Components: Format: PNG
> Affects Versions: 1.0-alpha1
> Reporter: Bruno P. Kinoshita
> Priority: Minor
>
> Today I was looking at the ICCP chunk type and the PNG image parser, and
> noticed that it was using the deflate compression only, regardless of the
> compression method value passed by the user.
> The documentation does say that deflate (0) is the supported compression, but
> that vendor implementations may use different compression algorithms. So
> instead of trying to use deflate (which would raise a runtime exception), we
> should inform the user that the compression method is not supported.
