Re: IMAGEOP Block
Hi David,
Thanks for investigating it.
I am using java 6 on a linux box.
Unfortunately my java is not up to debugging it.
Would it work if I replaced the 2.1 jar with the 2.2 one
Regards

Hi
Cocoon 2.1.12
I can't get scale and resize function in the imageop block to work on
cocoon 2.1.12.
I have the following working
* Display image with original size and colour
* Tint image various colour
Miguel has been kindly helping me, but he uses cocoon 2.2. Miguel has it
working on 2.2, see below.
Is there a difference between your versions of Java?
Please, has anyone got imageop scale and resize working on 2.1.12?
No. I looked yesterday at Cocoon running locally using the SVN branch
2.1.13-dev
The block samples show the same as what you described above.
The cocoon log file does show the errors, but doesn't mean much to me.
This was with Java 8.
The only thing that i can suggest is to look at the changes that
have been made to the code in 2.2 and compare with 2.1 branch.
http://svn.apache.org/viewvc/cocoon/branches/BRANCH_2_1_X/src/blocks/imageop/
http://svn.apache.org/viewvc/cocoon/trunk/blocks/cocoon-imageop/
Perhaps when the last changes were made, then there was a slight
difference, and perhaps no-one tested after that.
Those last changes seem to be
https://issues.apache.org/jira/browse/COCOON-2169
https://issues.apache.org/jira/browse/COCOON-2177

Thanks

This block has only three bugs, and all are fixed, so I think module

As I believe it will be the easiest to implement, I am going to try imgscalr.
However, As I am using cocoon 2.1, Is there a way of using
