Image Operation Reader

           Summary: Image Operation Reader
           Product: Cocoon 2
           Version: Current CVS 2.2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: blocks
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: niclas@apache.org


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.
