I have PDF file (structured form) that I fill in, and I use Adobe Acrobat Reader DC (version 2019.xxxxx) drawing tool to draw a signature in the file.
Using the API, I would have expected to find the drawing as an image in the Resources.Images collection of the page. But the collection is empty. The drawing, however, is saved somewhere (re-opening the PDF in Acrobat shows it).
- Where can I find the drawing?
- In addition, is it possible to get its Rectangle properties (left, right , top, bottom) ?
