Subject [jira] Commented: (COCOON-1301) [Patch] Image Operation Reader
Date Wed, 01 Feb 2006 15:36:05 GMT
    [ http://issues.apache.org/jira/browse/COCOON-1301?page=comments#action_12364816 ] 

Jean-Baptiste Quenot commented on COCOON-1301:
----------------------------------------------

Thanks for your contribution, looks promising!

After a quick test, it seems that all rotate and mirror samples give a black image.  You clearly
stated this in your comment, shall I remove those samples and corresponding source code, or
do you have a fix at hand?

And the "blur" gives the same as "sharpen".  Looking at the sitemap, the convolution parameters
are the same as "sharpen".  Can you give the correct parameters?

I'd be glad to add this block very soon.
