How to configure custom transformer

viralshah

I understand that Alfresco currently doen't have provision to add watermark when converting word document to PDF. Suppose one writes a custom transformer to add watermark to existing PDF.
So it will be like:
Inbound Word->Out of box transformer->PDF->Custom transformer->PDF with watermark

How to configure such a transformer chain in Alfresco as the mime type would be same (i.e. PDF) for source & destination of the custom transformer.

Yes that would be a problem, the mime type is not being changed.

Instead you could drive your conversion through the rendition service or a rule. My first thought is that a watermarked pdf is a rendition.

may be you should use another approach for instance:

 <bean id="transformer.PdfBox.TextToPdf"
         class="org.alfresco.repo.content.transform.TextToPdfContentTransformer"
         parent="baseContentTransformer" >
      <property name="explicitTransformations">
         <list>
            <bean class="org.alfresco.repo.content.transform.ExplictTransformationDetails" >
                <constructor-arg><value>text/plain</value></constructor-arg>
                <constructor-arg><value>application/pdf</value></constructor-arg>
            </bean>
         </list>
      </property>
   </bean>‍‍‍‍‍‍‍‍‍‍‍‍

then you check out the code for TextToPdfContentTransformer http://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/source/java/org/alfresco/repo/content/transform/TextToPdfContentTransformer.java

and see that in the bottom you have code

PDDocument pdf = null;
        InputStream is = null;
        OutputStream os = null;
        try
        {
            is = reader.getContentInputStream();
            pdf = transformer.createPDFFromText(new InputStreamReader(is));
            // dump it all to the writer
            os = writer.getContentOutputStream();
            pdf.save(os);
        }‍‍‍‍‍‍‍‍‍‍‍

and you add code for watermark .
so if you follow this idea maybe it would prove to be good way if I have understand you well.

I am in a similiar situation to convert image pdf to readable pdf. Upon thinking further I was wondering if the following would be possible

create a new mime called fdf
rename the original.pdf file to original.fdf
run the transformer from source fdf to pdf

I might not need help creating a new mime however how do i rename the file to fdf ?

edwardlobo

can i call mv for instance from a transformer to transform orginal.pdf to original.fdf
