Hello.
When I tried your class library, I found that I couldn't extract the images from this PDF file.
This image does not seem to exist in the form of an image. What is the method to extract this image?
Thank you

This may seem like I want to extract an image, but how do I access it or save it as an image?

I'd have to check the PDF reference to see what type XObject and subtype Image actually means. But I don't have the time.

So please check the PDF reference and see what's in your PDF file.
