[ http://issues.apache.org/jira/browse/COCOON-1301?page=all ]
David Crossley updated COCOON-1301:
-----------------------------------
Bugzilla Id: (was: 31718)
Other Info: [Patch available]
Description:
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.
