(x + width) is outside raster (CAPTCHA continued...)

[Andrew Madu]

Hi,
can anyone explain to me why, under cocoon 2.1.9, the following error is being generated?:

org.apache.cocoon.ProcessingException: Failed to process reader at <map:read type="captcha">

The code I am using that causes this problem is as follows:

Sitemap:
      <map:match pattern="simple.jpeg">
        <map:read type="captcha" src=""
      </map:match>

myFile.jx:
       <img src="" />

What is the issue here, is this a bug?

regards

Andrew
