As mentioned in FlexiCapture 12 FormDesigner documentation, after exporting an image to the PDF format, you will be able to edit it in other form editing programs, such as Adobe Acrobat Professional.
The trial version of Adobe Acrobat Pro DC (not Reader) allows opening PDF form. It is fully editable and could be saved. Furthermore, it allows saving it as a Reader Extended PDF. After saving the document in this format it can be edited in Adobe Acrobat Reader.
Some important notes:
- From Adobe Acrobat Reader the form cannot be saved after editing. It can be edited and printed, but you can save it only using Adobe Acrobat Pro.
- Like a workaround "Printing as PDF" option can be used. After editing a form in Adobe Reader you can try to print it using Microsoft Print to PDF:
