Subject [jira] Commented: (COCOON-2133) Addition of "allow-enlarge" parameter to ImageOp resize operation
Date Wed, 02 Jan 2008 12:23:34 GMT


Robin Wyles commented on COCOON-2133:

I'd be happy to provide a test-case but I can't see how to set one up to test a Reader. Looking
at SitemapComponentTestCase I don't see a corresponding "read" method and I can't find any
test-cases for other readers in any other blocks. If you can let me know how I might implement
this test-case then I'll write it.

In the meantime I attach a revised patch that fixes a bug with the previous patch where scaling
with allowEnlarge property would be ignored when only one dimension needs to be reduced in

>          Issue Type: Improvement
>          Components: Blocks: ImageOp
>    Affects Versions: 2.1.11, 2.2-dev (Current SVN)
>            Reporter: Robin Wyles
>            Priority: Minor
>         Attachments: ResizeOperation.patch, RevisedResizeOperationPatch.txt
> The addition of an "allow-enlarge" parameter to the resize operation allows the user
to control whether an image should be enlarged by the operation. 
> This new  parameter is declared in the sitemap like so:
> <map:read type="imageop" src="image.jpg">
> 	<map:parameter name="prefix-preserve-ratio" value="true"/>
> 	<map:parameter name="prefix-allow-enlarge" value="false"/>
> 	<map:parameter name="prefix-width" value="320"/>
> 	<map:parameter name="prefix-height" value="240"/>
> </map:read>
