Aspose.PDF shape extraction problem

Aspose.PDF Product Family
1

I am using aspose .net pdf (22.5.0.0) in an ongoing project.
I’m trying to extract shapes from a pdf file.

Circles and squares in the attached pdf file are not extracted.
I tried extracting it using the three methods below, but the shape is not recognized.
There is information about adding shapes on the aspose API site, but there is no information about shape extraction.
Please tell me how to extract these shapes.

The content in the document you provided consists of graphical objects (Paths). They can be extracted using GraphicsAbsorber - but this capability was added to the library in 2023.
