Hi Andrew,
What am I missing here? It seems that #{$cocoon/parameters/value} is not
working?!?
the code I copied into the previous email was just an example. Did you check
out the cocoon samples?
Are you getting errors in your logs?
Could you check a couple of things:
- What cocoon version are you using?
- Is the svg2jpeg serializer defined in your application?
- Is the Batik block included in your application lib directory?
Regards,
Reijn
regards
Andrew

According to the samples in cocoon 2.1.9 this is correct.

Yes you can find this in the samples when you build cocoon 2.1.9.

Yes it is. I you use an SVG for the captcha image you can modify all
these properties.
You will have to have something like this in your sitemap:
<!--
| Generate the CAPTCHA image. Any type of generator can be
used here,
| as long as it reads the string to display from the session
| attribute named "captcha-{1}".
| Using an SVG file as input requires that the Batik block be
| included in the build.
-->
<map:match pattern="captcha-*.jpg">
<map:generate type="jx" src=" captcha-image.xml">
<map:parameter name="value"
value="{session-attr:captcha-{1}}"/>
</map:generate>
<map:serialize type="svg2jpeg"/>
</map:match>
With the following captcha-image.xml
<svg width="210" height="75">
<defs>
<filter id="blur2">
<feGaussianBlur stdDeviation="2"/>
</filter>
</defs>
<g id="imagegroup">
<text
style="fill:#0086B3;font-size:42;font-family:Courier;filter:url(#blur2);"
x="0"
y="48">#{$cocoon/parameters/value}</text>
</g>
</svg>
I hope this helps you out a bit more. It's best if you take a look
at the samples in Cocoon. It will give you a nice
code overview of how to enable captcha for you website.

Reijn
