right I am now generating an image but the image is just white, there is no text to be read. What I have done is as follows:
sitemap:
<map:match pattern="captcha.svg">
<map:generate type="jx" src=""> <map:parameter name="value" value="{session-attr:captcha}"/>
</map:generate>
<map:serialize type="svg2jpeg"/>
</map:match>
svg_capture.jx:
<svg width="50" height="50">
<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">#{$cocoon/parameters/value}</text>
</g>
</svg>
jx template:
<img src="" width="50" height="50"/>
What am I missing here? It seems that #{$cocoon/parameters/value} is not working?!?
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.
