You want to annotate the image using AEM workflow?

Can you please give some more details on your use case

Open the form in AcrobatFrom the File MenuChoose the second option(Enable More Tools....) and save the filethis file can then be saved with Reader 

you mean you are not able to save the form when using Adobe Reader? 

The easiest option is to use the same xsd with your xdp and adaptive form so when you submit the adaptive form you can merge the data with xdp to generate the pdffor images you will have to include the base64 encoded string in the xml 

yes, you can always take the data filled in the Adaptive Form and merge the same with xdp template to generate PDF 

The following is working on my cloud ready instance if you are testing it on your author instance make sure you are wcmmode=disabled in the URL as shown adding http://localhost:4502/content/dam/formsanddocuments/thankyoupage/jcr:content.html?wcmmode=disabled&owner=admin&FormSubmissionComplete=true&f...

have not tried on cloud service. will try and let you know

Submit the form using the form data model submit buttonassociate the thank you page with the formthe thank you page will be based on new adaptive form template and in that templates jsp write the logic as I have written in the earlier reply

HiHere is a sample of the requirement and the solution. On submission of the form, a new case is created in ServiceNow using the form data model submit method. The thank you page will display the response returned by the form data model.Let me know if this works for you
