Re: Resize images

I've done some test and modulo in cocoon 2.2 project works fine. I 
describe step by step:

a) Include dependency into pom file of my project:

<dependency>
       <groupId>org.apache.cocoon</groupId>
       <artifactId>cocoon-imageop-impl</artifactId>
       <version>1.0.0-SNAPSHOT</version>
</dependency>

b) Include test map:match into sitemap.xmap:

<map:match pattern="prueba/*/scale-*-*">
         <map:read type="image-op-scale" 
src="themer/themes/common/images/{1}">
           <map:parameter name="scale-scale" value="{2}" />
           <map:parameter name="output-format" value="{3}" />
         </map:read>
       </map:match>

       <map:match pattern="prueba/*/resize-*-*">
         <map:read type="image-op-resize" 
src="themer/themes/common/images/{1}">
           <map:parameter name="size-width" value="{2}" />
           <map:parameter name="size-height" value="{3}" />
         </map:read>
       </map:match>

"themer/themes/common/images/" is the route to my images's folder

c) start my project and I test:

* http://localhost:8080/prueba/audio.gif/scale-2.5-jpg
* http://localhost:8080/prueba/audio.gif/resize-100-50

All works fine.
