Subject [jira] Commented: (COCOON-1301) [Patch] Image Operation Reader
Date Wed, 08 Feb 2006 09:09:18 GMT
    [ ] 

Jean-Baptiste Quenot commented on COCOON-1301:

Committed in 2.1, thanks for your contribution!

This issue remains open until the block is added in trunk.  The latter is currently in state
of flux, so there might be some delay.

> ------------------------------
>          Key: COCOON-1301
>          URL:
>      Project: Cocoon
>         Type: Improvement
>   Components: Blocks: (Undefined)
>     Versions: 2.2-dev (Current SVN)
>  Environment: Operating System: other
> Platform: Other
>     Reporter: Niclas Hedhman

>     Priority: Minor
>  Attachments:
> I would like to contribute a fairly flexible and powerful Image Reader that is capable
> performing a stack of Effects, such as Scaling, color manipulation, and coordination

> transforms (rotate, mirror and so forth), in a pluggable manner. 
> The ImageOpReader also reads any of the graphics formats supported by javax.imageio 
> package in JDK 1.4, including Png, Jpg and many more.  
> Any image can be returned to the client browser in any of the supported formats. 
> There is still a problem with the AffineTransform operations, and I am working on sorting
> out, but; 
> 1. The block is already useful to many as it is. 
> 2. I could need some help getting the AffineTransforms to work properly. 
> Stuff that is still left to do; 
> * Image Operation tests. How does one test image tranforms? 
> * JavaDocs. 
> * User Documentation 
> * Get Rotation & Mirror transforms to work. (Problem related to clipping outside
the positive 
> coordinate system.) 
> * More samples - The bulk are in place, but more doesn't hurt. 
> I would *really* appreciate if the ImageOp block becomes part of the standard Cocoon
> distribution. I am willing to help out maintaining it for the long term, if I am allowed
> P.S. I already have a CLA on file with the ASF.
