Hi Victor,

Pass a dummy source file that exists and don't use and pass any extra =
info through the <map:parameter>

Asunto: Creating images dinamically

Hello!
        How can I create images dinamically without knowing the source =
file
previously?

        I am using <map:read type=3D"MY_TYPE" src=3D"<FILENAME>"

        MY_TYPE has been defined by me and extends the Cocoon's =
ResourceReader
class.

        My problem is that to use the Reader, the src attribute file =
must exist (In
the processStream method I have an InputStream for that file).

        I need to create Images dinamically, without previously knowing =
the source
file. For instance, the request .../images/xpto (being handled by =
MY_TYPE)
can answer with file xpto.jpg or foo.png or any other thing.

        Does any one have any hint on how can I do this?

        Thanks in advance,
                Victor Batista
