  • Hello,

    Is this is compatible with Appian 19.3(cloud), As I tried to upload below error occurred?

  • Hello,

    I have a quick question regarding the Compress PDF smart service. The node input "Quality" takes a number, but I'm not sure what that number refers to. Is that a 1 to 10 scale like you see sometimes when creating/saving PDFs with other applications? Thank you!

  • Hi. Thank you for this plugin. We really enjoy it Slight smile

    We are using the smart service "Convert PDF to Image", and the function "Get PDF Text". Both of these, and probably the same for every smart service+function in this plugin, have the risk of throwing an exception when provided with invalid PDFs. I.e. when you have a PDF that is valid to view in documentviewer, but have corrupt metadata. 

    We are using it on arbitrary PDFs and we have a small percentage of PDFs failing to progress through the process. It is currently not possible to perform exception handling in a process model, so it would be nice to see a version of this plugin where exceptions are caught and returned through output parameters. 

  • Hi Chris,

    I have installed PDF tools plug-in in cloud environment, however I was unable to see the function named "Get PDF Form Fields",

    I have checked the source code file named "PDFToolsFunctions.java" for the function but no luck

    Can you please help me on this.

    Cloud version : 19.4

  • Hi Chris 

    We've just updated the PDF Tools plug in to the current version and I note the Admin Console is showing the version as 

    <version>2.2.5-SNAPSHOT</version>

    Is this the correct version of the Plug In for use ? 

    Many thanks

  • Hello,

    We are trying to install the PDF Tools plugin within our on premise Appian environment, but are encountering an error message along the way. We are using 19.3.81.0 (19.3 with Hotfix C) and are using MySQL8.x for the database on an Amazon Linux 2 server.

    The error is the following:

    Appian Plugin Hot Deploy] ERROR com.appiancorp.plugins.LoggingPluginEventListener - Failed to enable Plug-in 'PDF Tools' (pdftools) version 2.1.0: 'There was a problem loading the module descriptor: Fill PDF.<br/>com.appiancorp.suiteapi.common.exceptions.AppianRuntimeException: com.appiancorp.process.admin.IncompatibleSmartServiceRegistrationException: The Smart Service Module was invalid: Illegal attempt to change the data type for smart service pdftools.FillPDF, input or output named PdfFields (APNX-1-4104-005)

    I'm new to the admin side of Appian and am not overly familiar with a number of details. f this is the wrong place to pose this question, please let me know.

  • Hi Team,

    I have facing some issue in smart service ( "PDF FROM HTML"). I got the error like "java.lang.NullPointerException". I am sure and I gave all details in smart service but still cannot find the issue.

  • Hi, we're running into issue with the Merge PDF feature where embedded fonts are not being deduplicated (greatly increasing the size of the final PDF). Does anyone have a method to optimize the final PDF?
