    Hi,   Did a bit more digging into my issue.     I feel what might be occurring is in my use case the master PDF, pages 1&2, have the same PDF fields defined as those in the pages Im trying to merge with.     Ideally I would like to behavior of merge to merge the PDF fields as well as opposed to renaming them.    

    Not sure if this is feasible or not.   Before digging into the source can anyone provide insights to my challenge?   Is what Im desiring even achievable with the Java libraries used? 

    Regards,

    Bob

  • Hi,   I am using the merge PDF smart service node with  PDF pages which have fillable PDF fields where in the resulting PDF document the field names are getting altered in the result fillable PDF.   

    The  screen captures below show the  field names before the merge and after the merge.  After the merge the field names are dummyFieldName1...dummyFieldName##.     

    What would cause the PDF field name changes and is there anything I can do to stop this behavior?

    Before:

    After:

    Hello Manjit,
    I am not sure if this plugin is suitable for a 1:1 conversion from PDF to another format.
    -> can you challenge this requirement?

    Hi Chiara, 

    It tested SVG with the current version. I got the following errormessage from the plugin:

    "Error converting image to PDF"
    so it looks like SVG is not in the scope.

    Kind regards,
    Richard

  • in reply to Richard Michaelis

    If this a possibility I would certainly be interested. But to start with I was just trying to understand if the function could be supported. Thank you .

  • in reply to Chiara Gambone

    Hi Chiara, i will evaluate this, if you are interested :)

  • Hello, I am trying to use the "Convert Image to PDF" Smart Service.

    Trying to convert an .SVG file to PDF, an unspecified error occurs. Is this as intended? Are SVG images not supported?

  • Hi

    Previously working "Convert Image to PDF" smart service fails after plugin upgrade to v2.4.0 on 22.1 cloud environment.

    Using the "Convert Image to PDF" smart service to convert a tif to pdf.

    Delete plugin and re-added. Same error occurs.

    Process model fails with an error of "Convert Image to PDF   An error occurred in executing an Activity Class."

    The logs show the following:-
