I recently wrote a similar program using XsPDF library, which allows users to add interactive text in PDF pages. If you are interested in it, you may see details below.

• First, I create a document in InDesign and make it into a PDF file.
• Then, open the program and insert the text box that saved as PDF file.
• Users can open Acrobat Pro and select Advanced > Enable User Rights.

In addition, in this program, users can also insert operations within the image box. For example, when you click on a field, it will open the Explorer on your PC and you can browse the images. The format of image is not limited, and most raster image formats are available. Moreover, i also design a variety of scaling options for scaling images in the image box.
