>         Environment: Operating System: other
> Platform: Other

> I would like to contribute a fairly flexible and powerful Image Reader that is capable
of 
> 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
these 
> 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
2.2 
> distribution. I am willing to help out maintaining it for the long term, if I am allowed
to...

> P.S. I already have a CLA on file with the ASF.
