About the size of the image displayed on the document

I want to make B's image size on document the same as A's size.

A and B use the same image.

A: Acrobat tool [Edit PDF] -> [Add Image]

B: Read file in plugin -> Extract image data from file -> Create PDEImage in Acrobat SDK -> Add to document

So, please tell me the following.

  1. 1. How is the information of the image(size and resolution) related to the size on the document (the value of a and dof ASFixedMatrix)?
  2. 2. If there are elements that influence the size on the document in addition to the image size and resolution, I would like you to tell me something.

That’s doing it the hard way!

Images are XObjects, which mean that you can simply refer to them from multiple pages – you only need the CosObj (not the actual data).

So use the PDFEdit APIs to get the CosObj and attributes (such as page location, matrix, etc.) from A, then use them to create the PDEImage for the second page.
