How to analyze PDFs for regression testing

Hello Aspose,

for testing the PDFs generated with ASPOSE.pdf before I have to analyze them in regression tests for content and formats. Stepping through the forums and documents I did not find a good idea how to reach this.

So I would like to give an example and hope for good ideas how to open and analyze the PDFs accordingly.

I generated a test PDF with the required content as attached.
My test requirement is: "Image is displayed left aligned and has caption below image"
My test idea was to step to chapter 1. and look at the image and its image text.

But I have no idea how to.
Thanks a lot for your support
Regards
Gerd
