Capabilities of PDFTron for Interacting with Imported PDFs

All shapes are generally represented as annotations to make changes or use the annotation functionalities.
For text based annotations, we use the quad property, whereas other annotations will use the Rect property:

Rect-and-quads | Apryse Documentation

But please note that this will require you to either save the annotations (externally as XFDF data) or have it embedded within the input PDF.

For WebViewer, we do not have capabilities for extracting shapes from a document without annotations. This can be possible with our Core SDKs, please see this forum post for more information:

How can I extract vector shapes from PDF as '.NET' GraphicsPath objects?

Q: I need to read a PDF file containing relatively simple vector shapes and to convert the vector shapes into a .NET GraphicsPath. The GraphicsPath will later be used to draw the shapes. Even though your SDK may provide the ability to render/rasterize a PDF, I need to manipulate the data in vector format (GraphicsPath). Does PDFNet SDK provide this functionality? ------ A: Using PDFNet SDK (http://www.pdftron.com/net) you can extract vector data and other content from PDF documents. As…

Implementing a PDF semantic engine

Q: I'm working on a semantic engine and I'd like to introduce a PDFdocument manager able to recognize the tables in a pdf document. Is PDFNet library currently able to extract these information? Otherwise, is it possible to extract spatial information about words, images and graphical shapes? ---- A: You can use PDFNet SDK (www.pdftron.com/net) to extract any information from PDF documents (including text, images, positioning information, graphics state attributes, etc). As a starting p…
