----------------------------------------
Assignee: Alfred Nathaniel
> ImageOp with requested height & width both zero should be a no-op, instead it
> throws an exception

> Key: COCOON-2177
> URL: https://issues.apache.org/jira/browse/COCOON-2177
> Project: Cocoon
> Issue Type: Bug
> Components: Blocks: ImageOp
> Affects Versions: 2.1.8, 2.1.9, 2.1.10, 2.1.11, 2.1.12-dev (Current SVN),
> 2.2
> Reporter: Mark Lundquist
> Assignee: Alfred Nathaniel
> Priority: Minor
>
> When the resize height and width are both zero, the resize operation throws:
> java.awt.image.ImagingOpException: Unable to invert transform
> AffineTransform[[0.0, 0.0, 0.0], [0.0, 0.0, 0.0]]
> Note, if COCOON-2169 is fixed, this happens when no height or width parameter
> is passed from the sitemap. In this case, the resize effect should simply
> pass through the unaltered image... it should be a "no-op".
> The patch is too small to bother attaching, here it is:
