Date Mon, 31 Dec 2007 12:41:43 GMT


Grzegorz Kossakowski commented on COCOON-2048:

Is there anyone going to take care of this issue in upcoming two weeks so this can be closed
before 2.2 final release?

Alexander, are you sure your fix is working fine? I have no time to check it but I could apply
your changes if you assure us it is ok.

> New OverlayOperation that puts another image on top of the image used by the ImageOpReader.
Useful to overcome problems with browsers like IE that cannot put a transparent <img>
on top of a background image.
> Example usage:
>      <map:read type="image-op-overlay" src="background-image.jpg" >
>           <map:parameter name="overlay-offset-x" value="10" />
>           <map:parameter name="overlay-offset-y" value="20" />
>           <map:parameter name="overlay-source" value="overlay-image.png"/>
>      </map:read>
