Subject [jira] Updated: (COCOON-2048) ImageOp: overlay a transparent image on another one
Date Thu, 19 Apr 2007 12:03:15 GMT


Alexander Klimetschek updated COCOON-2048:

    Attachment: delete.png

Transparent image to be placed in cocoon-imageop-sample/src/main/resources/COB-INF. It is
taken from the Tango Desktop project, so it seems that it is not compatible with the ASL...
Can be replaced by another transparent image, but be sure to rename the link in the samples.xml

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>
