  • "conversion error" with PDF plugin.

    I'm trying to compare data sheets with the PDF addon. I use to just get a text comparison. After updating to the latest BC3 version and installing the plugin all I get is a conversion error when I try to compare PDF files. Did this break or is it that the PDF format has been updated once again...

    PDF support is built in to BC3. You don't need to install anything to compare PDF files.

    To compare a PDF file in BC3, open it in the Text Compare.

    Check the "Tools > File Formats" dialog. The file format for PDF files is included with BC3 and should be listed in the bottom half of the format list. Check the top of the list for any new file formats you might have added that map to the *.PDF file extension. If there are any new PDF settings at the top of the list, uncheck the box next to the format to disable it.

      PDF documents not converting for Text Comparison

      I am having the same problem - PDF's don't convert.
      Email Support advised that I check the Security of the documents in Adobe Reader.
      "Page Extraction" is set to not permitted, and I can't change it.
      The documents were created in Nuance Power PDF 2.x and when they are opened in that application, there is no Security restriction for page extraction.

      Workarounds I have tried include:

      1. Copy the document and try to compare on that - Support said that would get rid of the 'lock'. Didn't work.
      2. Print to XPS - didn't work and use those documents instead of the originals - didn't work
      3. Print to Microsoft PDF - didn't work either

      1.When I open the documents in Nuance Power PDF v2.x, and I open “Security, Manage Security, the Page Extraction shows as “Allowed”.
      So, why are they showing as “not allowed” in Adobe, and is this really the reason they aren’t converting?
      Given that the copy/paste of the file to create a new copy didn’t work…and given that the copy was made from a “Save As’ copy of the original in Nuance Power PDF, the workaround isn’t happening.
      I thought I could change the Security in Nuance Power PDF, but they are already open…everything is ‘allowed’.

      I can't contact Nuance support because I can't remember my username and their website has no mechanism for recovering it. I will have to call Monday and hope they don't try to charge me.

      Other workarounds I've looked at include use 3rd party s/w such as CuteFTP but I'm reluctant to muck around anymore until I really understand what the problem is. Support suggests Linux, but I don't have it installed on my Windows machine and do not know how to use it.

      Support quotes:

      "Beyond Compare can open any file that has "Extractable text: True" when you check its properties, using Acrobat Reader. Or try our Linux product if that is available."

      "Open the pdf in a reader, such as Adobe Acrobat and check File -> Properties -> Security.
      The crucial property is Page Extraction. For example, in the screenshot below, the text cannot be extracted by Beyond Compare's 3rd party tool"

      "Are the pdf extractable? Many are locked and Beyond Compare for Windows or MacOS cannot touch the text inside. This means the third party module in our pipeline that converts .pdf to .txt failed. This is almost always because the owners of the pdf have locked it with a password. Nothing can be done except to find a copy of the file that is not locked. This problem has not been reported on Linux versions of our software as far as I know.?

        BC4 uses a command line utility called PDF2Text, while Adobe itself is the official PDF application. This sounds like a bug with Nuance Power PDF if Adobe, PDF2Text, and Microsoft Printing all see the Security set to prevent extraction. It looks like Nuance is the only utility reporting that extraction is allowed.

        To clarify, if you open the pdf file in Adobe Acrobat or Reader, and use the File menu -> Save As (or Export) -> as Plain Text (.txt) what error message is shown? If the official Adobe application blocks this, then I would expect most other applications to also fail, including BC4. If this process works, then we should get a copy of the problem PDFs emailed into support along with your (Help menu -> Support; Export) so we can test directly against them. If you can reply to your original email thread, and include a link to this forum thread, it would allow us to join these reports and better track the issue (what we've done and what we can still try to do).

          I should add that when contacting Nuance, they are likely going to be concerned if you can show the behavior issue in an official Adobe product, so you'll still want to run the above Save As Text test in Adobe Reader to see if extraction is allowed and what error is presented.
